The pattern of most hormone secretion is described as _______________.
zimovet [89]

Answer: cyclic

Explanation:

This pattern often fits in with daily body rhythms or with the sleep and wake cycle.

For example, Cortisol hormone accumulates early in the day, reduces towards the afternoon, and rises towards the end of sleep and maximizes during the morning hours.

Thyroid stimulating hormone (TSH) rises to the maximum point during sleep and reaches its low point three hours after the individual wakes up.

Growth hormone (GH) levels rise 90 minutes after sleep begins.

Which of the following is an acid?<br><br> NaOH<br> NaCl<br> HCI<br> CH4
riadik2000 [5.3K]

Answer:

HCl

Explanation:

Some easy ways to identify if a compound is an acid is to locate an H+ proton, while basic compounds will have an OH- ion.

Examine all the choices:

A) NaOH

Already, we see that OH is here, so it's a base, not an acid. Eliminate.

B) NaCl

This doesn't have an H+ or an OH-, so it's not an acid. It's actually a salt. Eliminate.

C) HCl

This does have an H+, so it's an acid.

D) CH_4

Although this does have an H, it's a hydrocarbon - an organic compound. So, it's not an acid.

The answer is thus C.
