Question 1
Your body uses dietary proteins as sources of:
amino acids
lipids
glucose
vitamins

Question 2
Which of the following is an example of epigenetics?
DNA damage due to sun exposure creates a change to one's genotype; this is passed on to the next generation
chemical modifications to proteins called histones make it more or less likely a gene will be expressed
chromosomes exchange genetic material during sexual reproduction; this creates new combinations of genetic material in the offspring
an abnormality of embryological development causes a section of a chromosome to be deleted

False

Question 10
Selye's experiments were considered important because:
They demonstrated that there is a different stress response for different types of stressors (e.g. temperature, needle pokes, etc.)
They emphasized the importance of allostasis rather than homeostasis in physiological functioning
They demonstrated that there is a general response to stress that is similar for a wide array of stressors
They suggested the HPA axis is the primary physiological system that mediates the stress response

Question 11
How does the immune system respond to a stressor that continues for a prolonged period of time?
Initially the immune response is suppressed but as the stressor continues the immune response becomes heightened
Initially the immune response is heightened but as the stressor continues the immune response becomes suppressed
Initially the immune response doesn't change but as the stressor continues the immune response becomes heightened
The immune response does not generally change when someone experiences a stressor
