-Cell is the basic unit and building block of life. It is bound by a cell membrane, and possesses a nucleus which acts as its brain. Arachnoidiscus ehrenbergi is an example of diatoms which are unicellular, therefore it is a cell.
<span>An incorrect number of
chromosomes is the most common form of genetic disorder that causes the fetus
to spontaneously abort. </span>The
human cells normally contain 23 pairs of chromosomes, for a total of 46
chromosomes in each cell. Error in one or more of the meiosis, mitosis,
maternal age, or environment are the possible cause of the chromosome
abnormalities. These abnormalities in the number chromosomes can cause problems
with development, growth and function of the body's systems. These changes can
occur in early fetal development, or in any cell after birth during the
formation of reproductive cells (sperm and eggs).
<span>This example is used to illustrate the point that there are times when context and purpose are not enough to resolve all issues or questions. Context means that you are considering your audience, where purpose means that you are understanding and contemplating why you are doing or stating something. Here, the author is illustrating how these can be unimportant to a solution.</span>
The method used above involves the determination and comparison of the genes of the three species of finches. So, the answer is
<span>(3) Obtain molecular evidence from all three species and identify similarities.
</span><span>The genetic makeup of the three species will show different similarities that can be used to relate the evolution of the different species.</span>
