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

Answer:

Homeostasis is the tendency of any system to maintain the internal environment constant. Homeostasis is very much important and each organ system help in maintaining homeostatic condition in the body. Without homeostasis, we cannot survive.

If a homeostasis condition gets failed they it may cause diseases or disorders in the body, for example, parathyroid hormone is released when blood calcium level gets low. It increase blood calcium level by releasing calcium from bone.

If this homeostatic condition gets failed and parathyroid hormone is released in the blood abnormally it can cause a disease called hypercalcemia. Therefore homeostasis is important for the body.

A newborn’s vital signs are documented by the nurse and are as follows: hr 144, rr- 36, bp- 128/78, and t- 98.6℉ (37℃). The Blood pressure finding would be concerning to the nurse.

<h3>What is the average blood pressure of a newborn? </h3>

The baby’s blood pressure rises as the baby gets bigger. Normal blood pressure for a newborn is 64/41. Between the ages of one month and two years, the average blood pressure of a child is 95/58. It is common for these numbers to vary.

<h3>Infants with hypertension</h3>

High blood pressure is characterized by increased blood pressure against the body's arteries (hypertension). This article is about infants with high blood pressure.

<h3>Causes of Hypertension</h3>

Blood pressure is a gauge for the health of the arteries and the workload of the heart. Two figures are used each time blood pressure is assessed:

The first (top) number is the systolic blood pressure, which measures the pressure of blood released as the heart beats.

The second (bottom) number, or diastolic pressure, measures the pressure in the arteries while the heart is at rest.

Readings of blood pressure are given as 120/80. These two numbers can be excessive.
