There are two species of freshwater shrimp that are introduced to a pond. The first species, Caridina cantonensis, is brightly c
Marina86 [1]

Explanation:

Natural selection is the mechanism that is responsible for the evolution of organisms.  

In the given case, the Freshwater shrimp has been introduced to a pond in which the two species with variations are introduced.  

The <em>C. cantonensis </em>is brighter in color whereas the <em>C. multidentata</em> is mottled drab in color. The predator fish can feed easily on the species which is brighter therefore <em>C. cantonensis</em> is more susceptible. The mottled drab species is not easily predated by the species.  

The 30 % offsprings of <em>C. cantonensis</em> can survive till the reproductive age  whereas 75% of C. multidentata. This shows that natural selection has acted on the color of the shrimp species selected against the predator fish species.

The species with mottled drab color is the result of the differential reproductive rate.

Which cell that was viewed is most likely a prokaryote?
spin [16.1K]

Answer:

Option C, Cell Y

Explanation:

Prokaryotic cells are the most primitive type of organism that do not possess a true nucleus in them. They do not even have true membrane-bound organelles.

The prokaryotes have a plasma membrane as their protective covering which helps them to survive in extreme conditions.

They also possess a rigid cell wall which also provides them protection and rigidity. Example: Archaea and bacteria.
