Ion distribution across the cell membrane and the Nernst equation
Dissertation - 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
Dissertation - 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...
The concept of originality within the traditional English Copyright & the French 'Droit d'auteur' opposition
Dissertation - 3 pages - Biology
Originality is a long-established and fundamental condition for the protection of intellectual work in France and England. However, the Court of Cassation and the House of Lords have quite a different vision of this concept. Indeed, the French courts consider that the originality of a work is...
Mycology
Dissertation - 3 pages - Biology
Mycology- sounds more like Mythology. But, the similarity ends there. The science that deals with the study of fungi including their biochemical and genetic properties is called Mycology. The word mycology has been derived from the Greek word ?????, which means fungus. This field of study is an...
Biological membranes
Dissertation - 8 pages - Biology
The three main components of biological membranes are carbohydrates, proteins and lipids, and each of them has an important role to play in the functioning of membranes. The first part of this document will detail the various compounds of the membranes and study their role in its operation. We...
Biological chemistry of yeast
Dissertation - 8 pages - Biology
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
Dissertation - 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
Dissertation - 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
Dissertation - 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
Dissertation - 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,...
