Somatic mutations are important to the evolutionary process; most cancers result from somatic mutations : True
What is somatic mutations?
Any mutation that happens in a cell other than a gamete, germ cell, or gametocyte is referred to as a somatic mutation because it involves a change in the DNA sequence of a somatic cell of a multicellular organism with dedicated reproductive cells. Somatic mutations are typically not passed on to descendants, in contrast to germline mutations, which can be transmitted to an organism's offspring. Plants, which lack a separate germline, and animals that can reproduce asexually by processes like budding, as in the case of members of the cnidarian genus Hydra, obfuscate this distinction.
The descendants of a cell inside the same organism will all carry somatic mutations, even if somatic mutations are not passed on to an organism's progeny.

Explanation:
Answer: Blood loss regulation
Explanation:
Positive feed back is response of body in which there is an increase in the effect of small disturbance and the effect is intensified on a system. The magnitude of the effect increases.
In case of blood loss the body releases clotting factors that helps in preventing the body from severe blood loss.
The body releases clotting factors and these clotting factors tend to release more and more clotting factors that begins the process of blood clotting in vessels.
This is an example of positive feedback which acts as a life saving cascade.
Noisy breathing is produced by enlarged adenoids.
The lymphoid adenoids are located in the upper airway between the back of the throat and the nose. They resemble tonsils in appearance. Adenoids that are enlarged indicate swelling tissue. The tonsils, esophagus, trachea, and epiglottis are among the components of the throat.
Snoring, mouth breathing, chronic congestion, nasal discharge, ear issues, sinusitis, and "nasal" voice quality can all be signs of an enlarged adenoid.
The rear of the mouth and on either side of the throat are home to the tiny, rounded tonsils. The adenoid is a mass of tissue that is situated above the roof of the mouth, behind the nasal cavity. Adenoids and tonsils combat infections and can expand if they do so.
A bacterial infection, such as one with the bacteria Streptococcus, may be the cause of adenoiditis. Adenovirus, rhinovirus, and Epstein-Barr virus are just a few of the viruses that might cause it.
Enlarged adenoid symptoms are:
- breathing through the nose is challenging.
- Poor breath and chapped lips as a result of mouth breathing.
- having a compressed or stuffed-nose sound.
- recurring nasal issues.
- Snoring.
- Obstructive sleep apnea or restless sleep.
- middle ear infections that recur or fluid buildup in children at school
