PYSC 101 MODULE 2 EXAM
True or false? Endorphin release can result in feelings of euphoria. TRUE
True or false? Dopamine’s role in the brain is clear-cut and straight-forward. FALSE
This portion of a neuron resembles a tree branch: DENDRITES
neurons carry information to the brain, while neurons carry information
away from the brain. Afferent, efferent
What is reuptake, in terms of how a neuron handles an excess of a neurotransmitter?
Neurotransmitters that are smaller are recycled back into the pre-synaptic neuron to be
recycled and reused again and larger neurotransmitters need enzymes to break them
down into smaller units in the synapse.
For the following questions, choose from one of the following answers to indicate the
word that best describes what is being presented: Alleles, Trait, Dominant,
Recessive, Homozygous, Heterozygous. Hint: the correct word should also fit
grammatically within the sentence!
a. Everyone in Max’s family is showing the of dark hair. Trait
b. Someone who is for a trait has two different alleles. heterozygous
c. Someone who is for a trait has two copies of the same allele. homozygous
d. While everyone in Max’s family has dark hair, some family members nonetheless
carry light-haired alleles. Given, however, that dark hair is the only trait being
expressed, it appears that dark hair is a trait. dominant
e. Macy is a 5’9’’ tall woman and her two sisters are 5’4’’ and 5’0’’, respectively.
