Answer:

Option A, Release of chemical signals by keratinocytes that have been damaged by UV light will increase the production of melanin.

Explanation:

Negtaive feedback mechanism of homeostasis maintains the stability of any internal condition or function through lessening of output of a system or through slow down of a functional system.  

Here in this case the keratinocytes function is reduced by damaging them on exposure to UV light which further triggers the release of chemicals that enhance the production of melanin.

Hence, option A is correct

Contact [7]

The ________________ releases hormones directly into the blood and the ________________ receives hormones from the hypothalamus
Radda [10]

The<u> neurohypophysis </u>releases hormones directly into the blood and the <u>adenohypophysis</u> receives hormones from the hypothalamus cells which in turn causes the release of more hormones.

What are neurohypophysis and adenohypophysis?

The hormones produced by the posterior pituitary are released into the bloodstream directly from the axonal terminals of their source neurons, this region of the pituitary is frequently referred to as neurohypophysis. Two peptide hormones, vasopressin, and oxytocin act as the structural base of a neuro-humoral system that coordinates fluid balance and reproductive function.

The anterior pituitary (or adenohypophysis), controls a number of physiological processes (including stress, growth, reproduction, and lactation). Melanocyte stimulating hormone is produced and secreted by the intermediate lobe.

It would be appropriate as you increase the time of an exercise to decrease the _____________ of that exercise.
Scorpion4ik [409]

It would be appropriate as we increase the time of an exercise to decrease the number of sets of that exercise because duration is more important for effective exercise.

<h3>How to make exercise more effective?</h3>

We should increase the difficulty and duration of an exercise to make it more effective because it produces overload. As an individual exercises at a higher level, the body adapts to the increased demand and this higher level leads to new form of your body.

So we can conclude that it would be appropriate as we increase the time of an exercise to decrease the number of sets of that exercise because duration is more important for effective exercise.

Ne4ueva [31]

The type of drug which can be used in volume only and not in any kind of healthcare setting is Amoxicillin 125 mg per teaspoon. It can also be ordered as a drug in the household measurement.

The common household system, the avoirdupois system, the apothecary system, and the metric system are all used in the field of pharmacy. In the majority of the world's regions, the household system is most prevalent among patients.

Gallon, quart, teaspoon, tablespoon, and a pint are the units used in this system. The majority of the time, liquid items are measured using these units of measurement. The majority of us utilise the household measurement system at home, typically in the kitchen.

More examples include the following: cup, tablespoon, teaspoon, piece, slice, a fraction (for instance, 1/4 pizza), ounce, fluid ounce, or other typical home items used to package food products (e.g., jar, tray).
