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.

Hyaline membrane disease is now commonly called respiratory distress syndrome (RDS). It is caused by a deficiency of a molecule called surfactant. RDS almost always occurs in newborns born before 37 weeks of gestation. The more premature the baby is, the greater is the chance of developing RDS
Answer:
fasciae or, the outer connective tissue just under the skin is part of the structural integrity of the muscle, it also allows the muscle to be able to contract and relax. it can also be used to reduce friction of muscular force.In doing so, fasciae provide a supportive and movable wrapping for nerves and blood vessels as they pass through and between muscles.
