Yes, it's important to prevent damage to the nerve cells because if they were to get damaged you could get paralyzed. When your nerve cells are damaged the signals to move different parts of your body don't make it through to the muscles which leads to paralysis.
<span>Factors that can increase mutation rates are high and low temperatures, food additives, and UV rays. All of these answers are correct. Mutation rates in genes vary depending on many environmental effects. UV rays, along with varying temperatures, can cause mutations during cell division due to the damage they impart on the cells that are dividing. Dangerous food additives are believed to cause mutations, as seen in animal studies (ie. aspartame causing cancer in rats).</span>
Answer:
Biological: 2) not applicable for extinct species.
Morphological: 3) relies on similarities of structures. The morphology studies the structures.
Phylogenetic: based in the history of the specie
Morphological and phylogenetic : 1) acommodates asexual reproduction and 5) species acceptance criteria can be subjetive
all three: 4) used by scientists in classification
