Answers

Answer:

negative, salt

Explanation:

ADH functions via a negative feedback mechanism that responds to blood salt concentration to maintain homeostasis.

What is homeostasis?

In order to maintain a constant state between internal conditions and the external environment, a cell's response to its environment is known as homeostasis.

Because of their complexity and uniqueness to living things, the coordinated physiological responses that keep the majority of the body's dynamic equilibrium in place have been given the name "homeostasis."

Ex: When it's cold outside, we start to shiver and use energy to stabilize our body temperature. This is where the cell regulates cell temperature, fluid balance, sugar balance, etc. through it.

Therefore, there is negative feedback that responds to blood salt concentration.

Blood capillaries are where the nutrients in interstitial fluid are obtained. Additionally, metabolic waste products can be stored in interstitial fluid.

A continuous glucose monitor will use a formula to offer a near estimate of what our blood glucose level is likely to be at that particular moment because the glucose level in interstitial fluid is not exactly the same as that in our blood.

What is chromosome ?

A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.

It is composed of three components, DNA, proteins and RNA,  amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.

Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).

The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome  is present in two forms such as Euchromatin and Heterochromatin.
