Humans, like all mammals, are diploid organisms. This means that we have two copies of each chromosome. In diploid organisms, one somatic cell would have two copies of each gene. This means that in one somatic cell, an individual carries two copies of alleles for long eyelashes, and also two copies of alleles for short eyelashes.
The answer to this question is letter C. <span>The organism evolved during identification.
</span>A scientist has correctly gone through all the possible steps in a dichotomous key, but has not identified an insect. He was not able to identify the insect because t<span>he organism evolved during identification.
</span>
Choices to this question are:
A) The scientist must have made a mistake.
B) The insect might be an unknown variation or a new species.
C) The organism evolved during identification.
D) The dichotomous key had to many questions.

Explanation:
Answer:
The "tail" of the molecule is made up of two fatty acids, which are hydrophobic and do not dissolve in water. Following the rule of "like dissolves like", the hydrophilic head of the phospholipid molecule dissolves readily in water.
Nonpolar Fatty Acids
I Hope this answers your question :)
