How is the nucleus involved in the production of enzymes? A. The nucleus translates the ribosomal RNA for the enzymes to be synthesized in mitochondria. B. The nucleus is involved in the packaging and transportation of enzymes outside of the cell. C. The nucleus receives the messenger RNA and is the site where enzymes are synthesized. D. The nucleus transcribes and releases messenger RNA signaling for the enzymes to be synthesized.

Answers

The correct answer is D. The nucleus transcribes and releases messenger RNA signalling for the enzymes to be synthesized.

The nucleus is the site of transcription, production of messenger RNA (mRNA). Because of that, it contains a lot of proteins that either directly are involved in transcription or are involved in regulation. mRNA is exported from the nucleus, after being post-transcriptional modified.

There are two species of freshwater shrimp that are introduced to a pond. The first species, Caridina cantonensis, is brightly colored with red and white stripes. The second species, Caridina multidentata, is more mottled drab in coloration. Fish have an easier time finding and eating Caridina cantonensis due to their bright colors. When each of these species reproduce they produce about 100 offspring, but only 30% Caridina cantonensis offspring survive to reproductive age, while 75% Caridina multidentata offspring survive to reproductive age. In this situation what is natural selection selecting for? In this situation what is natural selection selecting against? How do you predict this population will evolve? Identify how each of the listed conditions from the above scenario that influence natural selection.

Answers

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

The 30 % offsprings of C. cantonensis 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.

Final answer:

Natural selection is favoring the Caridina multidentata species due to its mottled coloration providing protection against predators, and acting against the Caridina cantonensis species due to its conspicuous coloring. Higher survival rates to reproductive age in Caridina multidentata suggest that, over time, this species will increase in population assuming other environmental factors remain constant.

Explanation:

In the given scenario, natural selection is favoring the Caridina multidentata species. The mottled and drab coloration is providing higher survival rates by offering protection against predation. On the other hand, natural selection is acting against the Caridina cantonensis species which has bright colors that make it easily detectable by predators, leading to its lower survival rates.

The given conditions of coloration and survival rates to reproductive age influence natural selection. The higher survival to reproductive age in Caridina multidentata ensures the transmission of its color characteristics to a larger number of offspring. This leads to the prediction that over time, the population of Caridina multidentata will tend to increase compared to Caridina cantonensis, assuming all other environmental factors remain constant.
