Question

question 18
which of the following is not a direct stimulus type for the release of hormones?
nervous system
a change in a level of a substance in the blood
another hormone
muscular contraction

question 19
angiotensin converting enzyme (ace)
converts angiotensinogen to aldosterone
converts angiotensin ii to aldosterone
converts angiotensin ii to renin
converts angiotensin i to angiotensin ii
signals for the release of aldosterone

Explanation:

For Question 18, the nervous system, changes in blood - substance levels, and other hormones can directly stimulate hormone release. Muscular contraction is not a direct stimulus for hormone release. For Question 19, angiotensin - converting enzyme (ACE) converts angiotensin I to angiotensin II in the renin - angiotensin - aldosterone system.

Answer:

Question 18: D. muscular contraction
Question 19: D. converts angiotensin I to angiotensin II
