Question 1

genes

individual inherit genes from previous generations

Question 2

types of genes

Answer 2

single or polygenic (multiple genes)

absolute (100% chance of being inherited) or pre-dispositional (requires a trigger)

Question 3

Answer 3

genetic code written in DNA

Question 4

phenotype

Answer 4

physical appearance that results from gene

Question 5

the cerebrum

Answer 5

2 hemispheres
4 lobes: frontal, temporal, parietal, occupital

Question 6

excitatory neurotransmitters

Answer 6

chemical messenger making it more likely to fire
increases activity in central nervous system

Question 7

inhibitory neurotransmitters

Answer 7

chemical messenger that reduces likelihood to fire
decreases activity in central nervous system

Question 8

evolution

Answer 8

organisms become adapted to environment

Question 9

natural selection

Answer 9

individuals compete for resources and those who survive pass on traits that lead to better survival and reproductive success

practical applications
high scientific validity

Question 11

limitations

Answer 11

oversimplified
biologically deterministic
