Answer:
a. maple leaf and oak leaf
Explanation:
Homologous structures are those that have the same evolutionary origin but fulfill very different functions, a good example could be the wing of a bird and the wing of an insect, the wings of birds, are modified front members and the wings of insects are "BRANCHES" modified
In the case of maple and oak leaves they are homologous structures because they have a common ancestor according to their genetic decoding, that is, even if they can look different or behave differently, they are genetically homologous structures.
Retroviruses also have the enzyme reverse transcriptase, which allows it to copy RNA into DNA and use that DNA "copy" to infect human, or host, cells.
What is DNA?
Humans and nearly all other species carry their genetic information in DNA, also known as deoxyribonucleic acid. The DNA of an individual can be found in almost all of their cells. The majority of DNA is found in the cell nucleus (where it is known as nuclear DNA), but there is also a tiny quantity of DNA in the mitochondria (where it is called mitochondrial DNA or mtDNA). Cellular organelles called mitochondria transform the energy from food into a form that can be utilized by cells.
Adenine (A), guanine (G), cytosine (C), and thymine (C) are the four
chemical bases that make up the code that stores the information in DNA (T). More than 99 percent of the 3 billion bases that make up human DNA are the same in every person.

Answer:
There are several different morphologies that describe particular bacteria and archaea. Archaea can have a round (cocci) shape or a rod (bacilli) shape.Bacteria can also be circular, rod, or a spiral shape (spirochete).
When limiting factors increases, diversity in population decrease.
