The most likely explanation, for this reason, may be that eukaryotic genes often incorporate introns while prokaryotic genes do not possess such a structural arrangement.
<h3>What do you mean by Gene?</h3>
A gene may be defined as a stretch of DNA that contains genetic information that assists in the production of functional protein.
The type of protein may change when there will be a change in the codons. A eukaryotic gene contains introns that are removed during splicing and the codon that codes for specific amino acid may form.
But in prokaryotic genes, no introns are there, and no splicing mechanism will occur, which leads to the formation of different codons, and finally, an alteration in protein may clearly be observed.
Therefore, the most likely explanation, for this reason, may be that eukaryotic genes often incorporate introns while prokaryotic genes do not possess such a structural arrangement.

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>.
Answer:
melanin affects how one looks (1st question)
cause and effect (2nd question)
Explanation:
for the 2nd question, its cause and effect because uv rays hit our skin and our skin is affected which gives us suntan.
