Question

question 1 (1 point)
homeostasis:
a) refers to maintaining a stable external environment.
b) refers to maintaining a stable internal environment.
c) refers to thermoregulation
d) use of an interneuron
question 2 (1 point)
the release of hormones by endocrine cells alters the:
a) the rate at which chemical neurotransmitters are released
b) metabolic activities of many tissues and organs simultaneously
c) action potentials across neurons
d) skeletal muscle contraction

Explanation:

• Question 1: Homeostasis is the process by which the body maintains a stable internal environment. It involves regulating various physiological processes such as temperature, pH, and nutrient levels. Thermoregulation is just one aspect of homeostasis, and an interneuron is a type of nerve cell. The focus is on the internal environment, not external.
• Question 2: Hormones released by endocrine cells are transported through the bloodstream and can affect the metabolic activities of many tissues and organs simultaneously. Neurotransmitters are related to nerve cells (not endocrine - cell - hormone release), action potentials are neuronal events, and skeletal muscle contraction is mainly regulated by the nervous system (somatic nervous system for voluntary and some reflex - related contractions).

Answer:

• Question 1: B. refers to maintaining a stable internal environment.
• Question 2: B. metabolic activities of many tissues and organs simultaneously.
