The Basic Mechanisms of Homeostasis Overview of homeostasis The term homeostasis was first coined by Walter Cannon in 1929 to literally mean ‘steady state’. It describes the dynamic equilibrium by which internal constancy is maintained within set limits by regulation and control. There are many examples of homeostatic control throughout the human body and in other living organisms‚ such as pH‚ pressure‚ and temperature. A concept important to homeostasis is the process of feedback circuits;

Briefly outline evolutionary mechanisms. Drawing on the psychological literature from more than one topic area of research‚ evaluate how well evolutionary theory provides a satisfactory explanation for human behaviour. The aim of this essay is to assess whether Evolutionary theory presents an adequate explanation for human behaviour. I will be drawing from different psychological literature‚ especially focusing on the research areas of sexual selection and parental care and investment. Evolutionary

Amino Acids Glycine is the smallest of the amino acids. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH‚ glycine will exist predominantly as the zwitterion. Alanine is a hydrophobic molecule. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. The α carbon of alanine is optically active; in proteins‚ only the L-isomer is found. Serine differs from alanine in that one of the methylenic
