Answer: The two prokaryotic kingdoms are Eubacteria and Archaea.
Explanation:
The kingdoms that contains organisms that are prokaryotes are Bacteria and Archaea. They are unicellular kingdoms and their members appear similar in shape and appearance. But, they are different from each other and that is why they are grouped into separate kingdoms. Bacteria are all known as prokaryotes, which are organisms that lack a cell nucleus and other membrane-bounds organelles, and tend to be less complex. Archaea does not have membrane-bound organelles either but they have a cell wall that does not contain peptidoglycan (which is found in Bacteria) and cell membrane uses ether linked lipids as opposed to ester linked lipids in bacteria.

Answer:
a process of change in a population through genetic variation over time
Explanation:
Answer: Directional Selection.
Explanation:
This process can be defined as the positive selection in which one phenotype is selected over the other phenotype, causing the allele frequency to shift towards the other phenotype.
The allele favored by directional selection is advantageous. There is a increase in the rate of reproduction and chances of survival.
Here, the population of rabbits are decreasing in size over a period of time because they adapted the burrows to live in. Gradually small size of the rabbits were favored.
This is an example of directional selection.
Genetics is the scientific study of genes - the instructions that govern a person's growth, development, and health. These are passed down from from parents to children via sexual production.
