Need an research paper on heart and circulation. Needs to be 5 pages. Please no plagiarism. The arteries undergo excellent hydrostatic pressure. The hydrostatic pressure is an ideal means of pushing fluids through the cellular wall. The walls of the arteries are so thick that the pressure cannot work alone (Pickering et al. 2005). There needs to be an outer fluid that facilitates diffusion out the arteries. In the opposite case, the walls of the capillaries are thin in order to allow the hydrostatic pressure to act gently in diffusing substances (Agustine 2000).

Permeable membrane plays a role in the fluid passage to the body and out of the body through diffusion. The fluids passed are of different nature and concentration (Agustine 2000). Their passage is dependent on some factors. These factors include pressure, concentration, and temperature of the molecules or solutes covering either side of a permeable membrane. The membrane and the solute are also factors that affect the permeability pressure (Sharon & Emily 2006). Alongside membrane and solute other factors such as solute size, solubility, property, and chemistry may also affect the strength of the permeability layer. In order for a membrane to function well, its permeability is designed to withstand certain levels of pressure (Agustine 2000). The lipid bilayer is a permeable membrane example. The plasma membrane surrounds the biological cells within the lipid bilayer. Phospholipids are also a semi-permeable membrane that is very specific to their tasks (Sharon & Emily 2006). The semipermeable membranes in the human body allow the passage of water and crystalloids from the blood. Even so, it does not allow the passage of plasma proteins. Most of the body cells lie outside the blood capillaries and vessels. Consequently, all the cells will require a balanced utilization of foods and waste disposal. The arteries are created of thick walls that will allow the diffusion of materials (Agustine 2000).

The arteries are involved in the transport of blood to the capillaries. The thin walls of the capillaries allow the permeability of water, food substances, and oxygen through to the individual cells (Pickering et al. 2005). Intercellular substances and tissue fluids vary in order to create accurate pressure for distribution. Some parts maintain the intercellular substances as solutions and in such a case, the tissue fluid acts as a medium for dispersion of colloidal amorphous substances. In some cases, the amorphous substance exists as a rigid gel (Agustine 2000).

Create a 5 pages page paper that discusses opuntia humifusa: the devil’s tongue. The plant is a low-growing and reclining plant that absorbs enough water during the rainy season and stores it in the succulent pads for use in the dry seasons. These fleshy pads are the stems of the plant and are ovoid-shaped with sharp needle-like spines along the surface that are biologically the modified leaves to help the plant reduce the loss of water into the atmosphere. These pads have clusters of thorn-like leaves that are very sharp. This is an adaptation to ride away animals that feed on the fleshy pads. The prickly pads earn the plant the name ‘devil’s tongue’ (Hahm, Park, & Son, 2011). The plant grows on the dry rocky area of limestone glades in open fields. The natural seed distribution method is through the small mammals and birds that eat the Opuntia fruit and excrete the seeds in different locations.

Opuntia humifusa is not native to most of the American States. The plant was brought into the habitat through displaced small mammals from Southern Canada. The succulent pads of the plant and the melon-like fruits are a great attraction to many mammals. They eat the fruits and then disperse the seeds to other areas where favorable conditions of moisture and warmth lead to germination and growth. Further, the pads, once buried in the ground and with favorable climatic condition tends to germinate and propagate themselves (Anderson et al., 2001).

Opuntia humifosa has a cultivation history in South Korea where it was used as a traditional natural coloring agent as well as a remedy to stimulate the immune system. It is one of the largest genera in Cactaceae, with almost 250 species. It exhibits the widest distribution of any genus in family Cactaceae, occurring from Canada to Argentina and in habitats ranging from tropical to subtropical dry forests, moderate deserts, and even temperate forests. Opuntia also has been introduced throughout the world for use as a foodstuff for humans and animals and as ornamentals. While apparently strange in temperate regions, this&nbsp.fascinating cactus still conveys with it some of the habits of its desert-dwelling relatives. The plant still prefers sunny and sandy conditions and flowers from June to July.

Write 5 pages with APA style on The Ingenious Design of Discovery Green in Houston Texas. Discovery Green is a combination of recreational and natural features in an urban space. Its designers, Hargreaves Associates, wanted to include as many natural elements as possible, and this included a lake, native trees as well as plant species that embodied Downtown Houston’s indigenous characteristics. Even the grasses planted on its lawns reflected this objective (ArchDaily 13).

On the other hand, its designers also wanted to provide patrons with unique recreational spaces. For this reason, they utilized different architectural structures. They created a performance stage in which reverends could enjoy various concerts on occasion. Stone seats are available right near the edge of the lake and a café building is also present. The café was meant to serve economic as well as functional purposes as it would be a source of income for maintenance of the park while at the same time host visitors interested in a few refreshments or a filling meal.

It is particularly interesting to note that the architects of the park had several hurdles to overcome while making the structure. The park was to be built on a sloppy area which had previously been used as a parking lot. This would have been a huge barrier and irritant if Hargreaves Associates did not think of creative ways of using the space. The group worked around the problem by creating an amphitheater that would meet both functional and aesthetic needs. The public could use it for entertainment purposes or performances and at the same time, the structure would camouflage the sloppiness of the terrain.

The architects also found resourceful ways of adding fun&nbsp.and delight to the area by working with modern equipment. For instance, they interwove a series of water jets at the interactive fountain.&nbsp.

Prokaryotes are considered of high significance in agriculture. They play a major role in the utility of biochemical cycles through maintenances of soil fertility and soil structures.4 This is done by either interacting directly or indirectly with plants. At plough, the bacteria in the soil are not evenly distributed, so they aid the components by forming extracellular polymeric substances.5

For a number of years before modernization, food preservation was done through microbial fermentation.6 Such methods were used to preserve food substances like cheese, flavour enhancement and alcoholic beverage production. Fermentation process goes through five basic stages. Despite the absences of biological knowledge during that era, the biology behind this concept is that living organisms are the agents of fermentation. This forms the basis of an industrial production process of chemicals like acetone and butane. The technique paved way for the development of organic solvents. The further development of this has led to exploitation of other possibilities of metabolites production.7

Nitrogen is considered a vital element to plants. however, it is available and abundant in the atmosphere as a non-compatible form to the plants because it is gas in nature. For it to be transformed into the required state, the facilitation has to be done with the aid of bacteria. This involves the work of the prokaryotes.8 Prokaryotes at this state live around the aquatic environment of the plant, in the soil and around the roots. In essence, plants become the terrestrial producers of nitrogen. When plants are eaten by herbivores, the nitrogen is consummated into their body, which is further synthesized into the constituent of nucleic acids. The acids are then broken down during digestion. This overall cycle, which is propounded by prokaryotes, is teemed as the nitrogen cycle.&nbsp.

You will prepare and submit a term paper on Comparing the Theories of Darwin and Spencer. Your paper should be a minimum of 1250 words in length. Terms such as “survival of the fittest” and “Darwinism socialism” are often misquoted or referred for each other. (Bowler. Dennet)

Charles Darwin was a British naturalist. He studied geology and biology of the area around the Pacific Coast extensively before producing his monumental work “Origin of Species” in 1859 to the world. Herbert Spencer was a British philosopher who showed early interests in physics, chemistry and natural science. By the beginning of the nineteenth century, the study of natural history had already proliferated into diverse fields such as religion, psychology, and other social sciences. Lamarck was widely credited by many to be the first scientist to put forward a consistent general theory of gradual evolution. Herbert Spencer was privileged to go through his work, right when he was 20, and this had a lasting impact on his subsequent intellectual thoughts and work. Thus, when we seek to study the difference between the Darwinian approach of evolution and that of Herbert Spencer’s, this connection plays an important role. (Caroll)

Darwin’s vision of the world was one of the ceaseless interactions leading to evolution and adaptation. The drivers to these were the quest for survival and reproduction. But for Spencer, the drivers were the realization of some good ideals. Spencer could never free his work without attaching some form of hidden divine stigma to it. His theories were progressive and teleological. The change is occurring because of the realization of a just goal. That is, it has in it the concept of “archetype” put forward by Aristotle. an ideal form with unchanging virtues or qualities or essence. Spencer has tried to justify the same ideal, but that it occurs over through a time period and evolves over generations. (Caroll)

When Darwin speaks of general evolution, he has a much longer time span in mind than Spencer.

I need some assistance with these assignment. defence of globalization Thank you in advance for the help! Rural households are simultaneously producers and consumers of agricultural commodities. In conjunction, with data indicators of households the ability to respond to the various shocks, improved targeting both research and intervention is possible (Kierzkowski, 1992).

Good data are the principle of a strong fruitful analysis in development and invention, for broad swaths in the developing countries. Basic data typify poor house poor households as net producers, sub-subsistence of the laborers. According to food shock in 2008, several studies have analyzed household data surveys. In the rural areas income-generating activities, the database distinguishes poverty impacts in the urban and rural areas. The disparate sources do provide useful information, which improves the estimate of the household wellbeing and the prevalence of the production system. The combination of the multiple analytical methods at the household provides a be a better description of decision and constraints faced.

In the calculation of the net production and consumption of each food and crop level, a household survey must be included. The requirement limits the number of household data sets. In order to solve the food problem at the household level, we use caloric indicators and expenditure. Moreover, food value produced at home for daily consumption we share the total expenditure is higher for the poor in African countries.

Diversity in income from crops are vital indicators of household, the ability to adjust production and its vulnerability to production shocks. Poor countries indicate a less specialization than in the rich countries which are more constituent which their literature, producers do not have who do not specialize in agriculture represents the bulk share in net produce. The net producers indicate of staples are also net producers of the multiple crops. It indicates that households may have the ability to adjust production among crops grown per year. Households do not grow more than one crop may still be venerable to the production of other crops (Klein, 2001).

I need help creating a thesis and an outline on Long-Term Health Impacts of GM Foods. Prepare this assignment according to the guidelines found in the APA Style Guide. An abstract is required. The harm from GM foods is enormous, and people should not risk their lives. Long-term health challenges make GM foods dangerous for human consumption.

The consumption of GM food has the potential of causing sterility and stunted growth in human beings. Compelling evidence from the animal feeding studies indicates that long-term use of genetically modified foods causes fertility problems and increases infant mortality rates. The laboratory animals fed on GM food had unnatural slow growth and developed hairy mouths (American Academy of Environmental Medicine). Consequently, the inability to reproduce can have far-reaching implications for the family and society. The couples who cannot have children tend to be unhappy in the marriage life. Although the sole purpose of marriage may not be to have children, the kids are important components of the family. The inability to reproduce presents tremendous emotional, physical, and financial burdens for couples, friends, and immediate, as well as, extended family. Many people might undergo a series of immense feelings of sadness and boredom. The feelings may turn into grief, which affects the relationships, and the infertile partner may fear that the other person might quit the relationship. Abbie argues that infertility compels the family to spend a lot of many seeking medical interventions (22). The financial burden may affect the immediate family and friends as well. Thus, the consumption of genetically modified food is harmful, and the health implications are costly.

In the United States, farmers claim that the pigs and cows feeding on the GM feed have developed infertility problems. The pigs and cows cannot reproduce after consuming the GM feeds (Smith 39). The intention of having domestic animals is to get yield. Arguably, the farmers spend enormous sums of money to acquire, feed, and manage the health of the livestock. The livestock&nbsp.management practices are not cheap, and the farmers invest both money and time to ensure that the cows and pigs grow healthy and reproduce. In essence, the joy of the farmers is to have fertile animals.

Compose a 1250 words assignment on determination of calcium. Needs to be plagiarism free! The expressions below are quoted directly from the Biophysical Journal. Pluronic-127 for 30–60 min at room temperature, followed by a 30-min recovery in EBSS at 37°C. Images were acquired using a high-speed Photometrics CCD camera (frame transfer EEV37 chip) on an inverted Zeiss microscope, controlled by Innovision software on a Silicon Graphics workstation. Coverslips were mounted on an open-welled chamber. The cells were bathed in pH-controlled EBSS and maintained at 37°C. Ratio pairs of 340- and 380-nm excitation were collected for some experiments, with emission passed through a rhodamine filter. Using this acquisition protocol, ratio pairs could be collected approximately once a second. Because the BK-induced calcium waves are typically very fast, faster imaging was necessary to resolve the geometry of the calcium wave propagation. Faster imaging was possible using only the 380-nm excitation wavelength, in which images could be obtained every 65 ms. Cell exposure

during excitation was kept to a minimum by using 4 3 4 binning (resulting in 128 3 128 images) and increased gain settings, but always maintaining at least a 5-to-1 cell-to-background intensity ratio. BK was added in 20-ml aliquots to the cell chamber so that the exposure was nearly instantaneous but with as little cellular disturbance as possible.” (Charles et al, 2000).

Physical properties: Calcium is a silvery solid, metal and has a melting point of about 64 and a boiling point of 773. It can act as a reducing agent. And it reacts slowly with water. Calcium is a divalent element with each of its atom having two valence electrons.

1. Flame Test: This is a procedure used in Chemistry to detect if some impurities are present in a particular substance. The test itself is simple and requires a few materials. Some of the materials needed are a chrome or Platinum wire, concentrated hydrochloric acid and a Bunsen burner that produces a flame.

Write a 5 pages paper on on the production function for agriculture.

Write a 5 pages paper on on the production function for agriculture. The origin of the Cobb-Douglas production function can be traced to the 1928 seminal work of Paul Douglas and Charles Cobb in studying the United States manufacturing sector using the data set of 1899-1922 (Felipe and Adams 2005, p. 428). However, Felipe and Adams (2005, p. 428) also pointed out that several authors like Paul Samuelson have argued that Knut Wicksell should have taken the credit as well for its discovery. Nevertheless, Cobb and Douglas’s econometric or empirical estimation of an aggregate production function was the first in the profession of economics (Felipe and Adams 2005, p. 428). The production function is discussed in Gujarati (2004, p. 224). In its Cobb-Douglas form, it is possible to know or estimate whether we have an increasing, constant, or decreasing returns to scale (Gujarat 2004, p. 244). In a way, the production function reflects the technological constraints or the production feasibility set (Varian 2006, pp. 322-327).

Meanwhile, we can see in the literature that the production function estimation has been supplemented by several techniques to improve precision or correct perceived weaknesses. Mittlehammer et al. (1980) employed mixed estimation and principal component regression to mitigate the effects of severe multicollinearity that was preventing accurate through ordinary least squares. The methods improved precision as well as the theoretical reasonableness of estimated parameters. Just et al. (1983, p. 770) developed a technique for the estimation of multi-crop production functions. Their method employed all available information and they claim that their empirical results show that their approach is practical and inexpensive. Mittlehammer and Conway (1988, p. 859) developed a mixed estimation procedure of the production frontier that departs from the Theil-Goldberger model that had been questioned in the literature. Mittlehammer and Conway (1988, p. 865) introduced instead a prior integrated mixed estimator or the PIME that are based on generally accepted principles.&nbsp.&nbsp.

Create a 5 pages page paper that discusses the biography of nikki giovanni. Giovanni’s truthfulness has been a huge contributing factor to her fame. Not only does it assure her admirers of her credibility but also allows her to make a definite mark on the Black community.

Giovanni’s life has undergone a number of different phases. From an all-black high school, she moved out of her parents’ house to live with her grandparents. Responsible for her sister’s child, Giovanni attained maturity at a very young age. She suffered the ordeal of changing schools, making sacrifices and compromising her life for those she loved. In 1967, Giovanni’s grandmother died, this was considered a painful and life-turning moment in the writer’s life. Her closeness to her grandmother is considered to be the most important loss in her life. It was, in fact, this death that drove her to write. The feelings of grief and loss motivated Giovanni to turn to her writings for comfort. Most of the poems written by her would later be used for the publishing of her first volume Black Feeling Black talks.

The Black Feeling Black Talks is a book that reflects the revolutionary stance that is so strong in Giovanni. This volume includes poems written about Black figures that have impressed and won over Giovanni over. There are like personal attributes to people who have affected and shaped the writer’s life and ideology. These include the deaths of John F Kennedy and Martin Luther King Jr. Many feel these works to have a militancy stance, showing the strong spirit of revolution present in Giovanni’s work (Lee 1971). In this volume, Giovanni also comments on the atrocities committed in areas like Vietnam and Germany and compares them to the 1960s’ in America (Fabio 1970). This volume is full of works by Giovanni that includes ideas of loss and loneliness which were a part of the writer’s life&nbsp.during the creation of most of these works. This is the first volume printed by the writer from borrowed money.&nbsp.
