Question

q 1.16 a decrease in antidiuretic hormone (adh) would result in:
a increased water reabsorption
b decreased urine production
c increased urine production
d no change in kidney function

q 1.17 the primary function of nephrons is to:
a pump blood
b filter blood and form urine
c absorb oxygen
d digest proteins

q 1.18 touching a hot surface and immediately pulling away is an example of:
a hormonal response
b voluntary action
c reflex arc
d long-term memory

q 1.19 damage to the cerebellum would most likely affect:
a heart rate
b balance and coordination
c hormone production
d breathing rate

Explanation:

Analyze Q1.16: ADH decrease

Antidiuretic hormone (ADH) promotes water reabsorption in the kidneys. A decrease in ADH reduces water reabsorption, leading to increased urine production (diuresis).

Analyze Q1.17: Nephron function

Nephrons are the functional units of the kidney. Their primary role is to filter blood, reabsorb essential substances, and secrete wastes to form urine.

Analyze Q1.18: Reflex arc

Touching a hot surface and immediately pulling away is an involuntary, rapid response mediated by a neural pathway called a reflex arc.

Analyze Q1.19: Cerebellum damage

The cerebellum is responsible for coordinating voluntary movements, balance, posture, and motor control. Damage to it impairs balance and coordination.
