oxidizer and can be used as a disinfectant to prevent infections. However when used incorrectly‚ hydrogen peroxide can cause oxidative stress on cells. This essentially means that there is an imbalance on molecules containing oxygen and the cell cannot detoxify the products. This creates free radicals such as hydroxyl radical that will damage all components of the cell‚ ultimately killing it (Tucker‚ 2012). However‚ humans actually produce

An experiment was run to determine which enzyme (pectinase‚ and cellulase or combinations of the two enzymes) maximizes juice production and would be most cost effective. The proposed hypothesis was if the enzyme‚ pectinase‚ is added to apple juice‚ then the more juice will be extracted than if cellulase were added because pectinase holds the cell wall together and if it is separated apart from each other‚ then the more juice would be able to flow out. The experimental data show that during the ten

PERSONAL POTRAIT: A BIOLOGICAL NARRATIVE 2 John C. Carter Capella University Dr. Janice J. Caron August 29‚ 2010 Abstract Eric Erickson is best known for his studies with psychosocial development‚ or the development of a person within a social context. Eric Erickson’s theories focused primarily on the correlation of the release of sexual tension and psychosexual development. The purpose of this paper is for the author to develop a personal portrait integrating Erickson’s developmental

Biological weapons include any organism (such as bacteria‚ viruses‚ or fungi) or toxin found in nature that can be used to kill or injure a person. The history of biological weapons starts back way before many people realize. Biological weapons have quite a few advantages and disadvantages. Biological weapons have been used as agents of terror and will continue to be used as such. Biological weapons are extremely dangerous and shouldn’t be used because they have the potential to wipe out entire

DESCRIBE THE STRUCTURAL COMPARTMENTATION OF MAMMALIAN CELLS AND THE DIFFERING FUNCTIONS OF THESE COMPARTMENTS? Mammalian cells are eukaryotic this means that all of their cells have common components‚ membrane bound organelles which prokaryotic cells do not this is shown in figure 1. Organelles are purpose made to carry out a specific function that is necessary within a cell. Due to the specificity of both conditions and concentrations with in these organelles these are compartmentalized. Encasing

Biologists and sociologists view the concept of human behaviours or characteristics quite differently. Biological explanations would suggest that it is genes‚ instincts‚ or evolutionary advantages that determine human behaviour. These types of explanations suggest human traits are predetermined and are difficult to change. Sociologists argue these are misguided explanations for human behaviour because this sort of definition takes away from the obviously observable variations in behaviour throughout

a) Using a human cell of your choice‚ describe how organelles work together to make and secrete a protein (LO1. AC 1.1) An epithelial cell in the thyroid gland‚ called a thyrocyte forms spherical follicles that produce a protein called thyroglobulin. This is a globular protein that has a functional role in metabolism. The protein is used by the thyroid gland to produce thyroid hormones; thyroxine (T4) is an example of one of the hormones created. Thyroxine is formed by iodine binding to tyrosine

Biological Anthropology What is researched within Biological Anthropology? Biological Anthropology studies the behaviours and biological variations of human beings‚ other primates‚ and extinct hominin ancestors. This subfield of anthropology provides us with a biological perspective on the variation of humans as a whole. What are some Biological Anthropology Research Methods? Since it is such a broad sub-discipline‚ the research methods tend to vary. Some biological anthropologists
