The answer is d because of heat and pressure
The answer is B because the humoral immune response is mediated by antibody
Answer:
Epinephrine binds to receptors on some smooth muscles (ex: around arterioles) → Ca++ released from ER → intracellular Ca++ up → stimulates contraction. c. Epinephrine binds to receptors on some smooth muscles (ex: around bronchioles) → phosphorylates protein needed for response to Ca++, preventing response.
Answer: The answer is A: The Inferior Colliculus
Explanation:
The inferior Colliculi play a major role in hearing. Since the loud noise was what prompted the response it is safe to say the inferior Colliculi is responsible.
Neurons in the inferior Colliculi respond to cues such as intensity, the difference red in arrival of sound to both ears.
However, the head snaps up because the information from the inferior Colliculi is transmitted to the superior Colliculi which is involved with movement such as the head.
