Answer:
An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These alterations can (but do not always) cause cancer or other diseases.
Explanation:
when a skin stem cell harbors a cancer-driving mutation, it becomes more likely to generate two specialized skin cells when it divides. Over time, the mutated skin stem cell fails to renew itself and turns into cells that eventually slough off, allowing the skin to expel mutated cells as needed.
Errors in DNA copying during cell division and development can cause new mutations — called de novo mutations — at any time from the moment of conception. Mutations that occur in the germ line — the cells that develop into sperm or eggs — can be passed on to the next generation and, perhaps, cause disease in children.
B the organ that turns into the shell of the animals
Answer:
C) phenotypic plasticity
Explanation:
- The ability of an organism to change phenotypically according to environmental conditions is known as <u>Phenotypic plasticity</u>.
Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.
Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.
- Sulfur-reduction bacteria are obligated anaerobic microorganisms, that are <u><em>metabolically versatile</em></u><u><em>. </em></u>They might grow either as heterotrophs using organic molecules or as autotrophs using hydrogen and carbon dioxide.
These bacteria are <u>notoriously adaptable</u> and <u>might be found in many different environments</u> (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.
<em>They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine</em>.
Water could not covert from a gas to a liquid.
