Mini - assignments for biological rhythms 1. Outline what we mean by an endogenous pacemaker (3) Endogenous rhythms are rhythms that aren’t imposed by the environment but generated from within the organism. Since many of our biological cycles follow an approximation 24-hour rhythm‚ even in the absence of external stimuli‚ it follows that there must be some kind of internal biological clock. 2. What is the name given to external events that play a role in rhythmic activities? Give

The psychologist taking the biological approach would respond with an explanation of how the brain may be deficient in a certain area. He/she may suggest that there is a chemical imbalance in the brain causing the irrational actions displayed by the criminal.

Question #1 For many years biological anthropologists have been trying to identify race through genetics but race is not determined biologically. The closest aspect to a biological feature in grouping people is cline; geography making people of the same area in the world similar. Human variation‚ however‚ is classification of skin color‚ eye color; characteristics that are genetic and unchanging genes. Genetic traits have nothing to do with race; it influences the idea of it.

Biological Currency The objective of this lab is to figure out whether or not this money is counterfeit. We will attempt to find the information needed to prove that the money is counterfeit or not by looking at it under a microscope and by using iodine drops to compare the money’s result with the results of different items. Counterfeiting money is not a new to any country. It started when paper money was first made. Some countries attempt to counterfeit rivals money to drive their economy downward

cognitive and biological factors interact in emotion. ( /22m) James and Lange proposed that the state our bodies’ are in effects the emotion we experience‚ however there is little difference in autonomic arousal between emotions so opposite as fear and joy.

Schater and Singer theorize that this factor is cognition and that it works in conjunction with biological factors to
