Answer:
A. These homologous structures indicate that these four organisms all share a common ancestor.
Explanation:
Homologous structures mean the organs will have similar structure, but not necessarily function (human arm vs whale's flipper). While analogous structures are similar in function but not structure (wings of an airplane vs wings of a bird). Since the question states that they are similar in skeletal structure, we know they must be homologous structures, thereby eliminating B and C. D is not a choice because the question does not provide anything about the order of evolution. Therefore the answer is A. These homologous structures indicate that these four organisms all share a common ancestor.
<span>Mitosis is the cell division that happens to replace old cells with new ones.
Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis. This
mechanism of each cell produces another cell that binds together and
produces again, repeatedly, to be a larger system called now the tissue
as explained earlier.How? Through cell division called, mitosis. Excerpt meiosis –cell division specifically in the sex cells.<span>
They are labelled as daughter cells. </span></span>
