An account on Chlamydia
Case study - 1 pages - Biology
Chlamydia is a STD (Sexually Transmitted Disease) and the causative organism for it is known as 'Chlamydia trachomatis'. They attach to the host cell with the help of specialized organelles called 'microvilli' which facilitates its entry into the cytoplasm. It mainly affects the...
Development of executive functioning and neural correlates of the inhibitory response

Analyzing Darwin's theory of evolution
Essay - 4 pages - Biology
As an intellectual Christian of this century, though I have had some training in biology more-so then the average intellectual, it is hard not to notice the work of Mr. Charles Darwin and the well detailed and grounded system of evolution. But he has made some major errors in his concept of man....
Ion distribution across the cell membrane and the Nernst equation
Thesis - 5 pages - Biology
The cell membrane is essentially a bi-lipid layer that contains phosoplipids and proteins. The concentration of ions and certain molecules is vastly different between the intracellular and extra cellular concentrations in cells across the cell membrane. This is because the lipid bi-layer in the...
Key mechanisms that are involved in expressing a eukaryotic gene as a protein
Thesis - 5 pages - Biology
The information contained within the DNA, in the form of a nucleotide sequence, is responsible for the production of the phenotype of an individual. The dna contains specific sequenmces of nucleotides, called genes, that code for specific chasracteristics. The basic concept of how this occurs...
Mycology

Products such as bread, beer, wine and cider depend on microscopic living cells that develop in a fungus. These are called Saccharomyces cerevisiae. A number of varieties of Saccharomyces cerevisiae exist in nature and are adapted to different kinds of fermentation. Yeast is said to have...
Effect of oxytocin on residual milk letdown and composition
Thesis - 4 pages - Biology
The Endogenous release of Oxytocin occurs in response to stimuli and mechanical release. Milk ejection is stimulated by the release of oxytocin from the posterior pituitary gland. The oxytocin then binds to the myoepithelial cells to squeeze milk out of the alveoli and ducts in the mammary gland....
Fruit abscission in physalis species in response to herbivory by heliothis subflexa
Thesis - 6 pages - Biology
Heliothis subflexa is a Lepidopteran caterpillar that feeds exclusively on Physalis spp. fruits. These fruits are encased in the inflated calyces—a characteristic that all plants in the genus Physalis share. Abscission of the fruits on which H. subflexa is feeding is a mechanism employed...
The use and abuse of biology
Essay - 1 pages - Biology
Although biology is useful it is not everything as it does not explain the motive of an individual. The motives of the individual may not be the motives of a society. In the example of war, the biological standpoint says that people go to war because there is an underlying aggression engrained in...
Genetically modified food
Thesis - 3 pages - Biology
Genetically modified food made from genetic material (DNA) of a plant that has been changed in an unnatural way, also known as ‘genetic engineering'. Selected individual genes are transferred from one organism to another. However, traditional breeding cannot achieve the same effects using a...
Role of changes in wavelength and light intensity on the rate of photosynthesis in the chloroplast of spinach leaves
Thesis - 4 pages - Biology
Photosynthesis is the conversion of solar energy into chemical energy in order to synthesize organic compounds necessary for plant life. The light reactions occur in the thylakoids of chloroplasts in spinach leaves. Inside the thylakoids are pigment molecules that capture and absorb light,...
Assessment of evolution in a population of University of Florida's students according to Hardy-Weinberg's equilibrium
Thesis - 3 pages - Biology
TPA-25 is an Alu element which is inserted within an intron of the tissue plasminogen activator (TPA) gene. An individual may be homozygous for the presence or absence of TPA-25, or heterozygous for it. Evolution occurs in a population if the frequency of alleles changes from one generation to...
Potential effects of road salt on the growth of quercus rubra (northern red oak)
Thesis - 2 pages - Biology
The practice of adding salt to roadways during winter months in the northeast is very common. While the exact quantitative effects of this road salt are relatively unknown, it is known that increased soil salinity causes a drastic reduction in growth and biomass of the ecosystem's vegetation...
Lab report of photosynthesis
Thesis - 2 pages - Biology
The majority of my data agrees with my hypothesis. I hypothesized that the color of light which would result in the highest photosynthetic rate for the spinach and red cabbage would be red (650-700 nm) and yellow (400-450 nm), respectively. To fully elaborate on such hypothesis, Table 1 below...
The effects of competition for resources on resulting plant biomass
Thesis - 3 pages - Biology
The purpose of this experiment was to determine the effects of competition for resources on resulting plant biomass and to analyze the differences between intraspecific and interspecific competition. The study quantified the growth of two different plant species, wheat (Tricticum aestivum) and...
DNA transformation of escherichia coli using plasmids
Thesis - 3 pages - Biology
During this lab, we performed a transformation of genes from one organism to another, more specifically, added genes to a bacteria. Our results displayed much growth (100+ colonies of small size that did not glow) on the +pGLO LB/amp plate. The +pGLO LB/amp/ara plate experienced growth (100+...
Finding if competition exists among the same or different species, and measuring it
Thesis - 3 pages - Biology
Plant competition is something that is very important to study. Like any other organism, plants must consume resources to survive. With limited resources, those that are most competitive generally receive the most resources, allowing them to survive. This lab investigates just that. Using 14...
Proteins in the American dietetic association on vegetarianism
Thesis - 11 pages - Biology
Official position of the American Dietetic Association on vegetarianism (1993): "soy protein proved nutritionally equivalent in quality to animal protein; therefore, they can serve as the sole source of intake protein if desired. Proteins are large molecules consisting of smaller units called...
Sufferings of marine animals
Thesis - 10 pages - Biology
Despite appearances that lead us to believe, the world of aquatic animals is extremely complex. Fish, like humans or other terrestrial animals, see, feel, suffer, communicate. Most fish produce sounds (unfortunately only audible through a hydrophone) when touched, when due, when continuing. Their...
How to produce billion eggs? Exploitation of laying hens
Thesis - 13 pages - Biology
A life of frustration, pain and stress. That is what sums up the life of a battery hen and to this suffering and many who are the corollary. This is corroborated by evidence from numerous scientific studies and behavior. Originally the term "battery farming" was used for hens, distributed in...
The glucose and sugar essential for energy
Thesis - 8 pages - Biology
The foods we eat provide us with energy and nutrients we need. Sugar, or glucose, is the main nutrient that feeds the body cells. The way energy is metabolized by the body is subject to variations over time and depending on the individual. The dietary intake was in fact never constant from one...
The power of nutrition in child and adolescent
Thesis - 9 pages - Biology
Childhood and adolescence are critical stages in the life of an individual, and feeding them is important. As for adults, nutrient intakes for children should cover the energy needs, but they must also ensure growth. The quantitative and qualitative aspect of their food is taken into account....
A study on immunology
Thesis - 19 pages - Biology
Immunology is a subject, which deals with immune system and immune reactions in our body. Immune system works by the principle of learning process. When a pathogen attacks for the first time, it leads to infection, but when it attacks for the second then our body's immune system recognizes and...
