Your friend comes to you with a problem. It seems his shrimp boats aren't catching nearly as much shrimp as they used to. He can

't understand why because he used to catch all the shrimp he could handle. Each year he added a new boat, and for a long time each boat caught tons of shrimp. As he added more boats, there came a time when each boat caught somewhat fewer shrimp, and now, each boat is catching a lot less shrimp. Which of the following topics might help your friend understand the source of his problem?
A) density-dependent population regulation and intrinsic characteristics of population growth
B) exponential growth curves and unlimited environmental resources
C) density-independent population regulation and chance occurrence
D) pollution effects of a natural environment and learned shrimp behavior
E) a K-selected population switching to an r-selected population

The correct answer is A. Density-dependent population regulation an intrinsic characteristic of population growth.

Explanation

Density-dependent population regulation includes factors such as diseases, predation, or competence that limit the growth of a population depending on the size of it (density). In the case presented, predation is the factor that affects the shrimp population because more boats and more shrimp imply more predation from humans. Additionally, this excessive predation limits the growth of the shrimp population and causes the depletion of shrimp over time. According to the above, the correct answer is A. Density-dependent population regulation an intrinsic characteristic of population growth.

I am Lyosha [343]

Since prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

<h3>What are prokaryotic cells?</h3>

Prokaryotic cells are cells that are characterized by the absence of a nucleus or any other membrane-bound organelles.

On the other hand, eukaryotic cells have the presence of a membrane-bound nucleus that stores their genetic material.

Another important feature of prokaryotic cells is that they are haploid in nature i.e. they do not have chromosomes that occur in homologous pairs and have just one chromosome.

Therefore, it can be said that because prokaryotic cells are haploid, they have the ability to adapt faster to changing environmental conditions than eukaryotic cells.

Ovules produced by an entirely green plant contain a rare mutation in a nuclear gene that is involved in chlorophyll synthesis,
sveticcg [70]

Answer:

The plant will produce less chlorophyll

Explanation:

The plant still has a functional allele provided by the paternal gamete, thereby the leaves have this enzyme required for chlorophyll biosynthesis. In consequence, the plant can produce chlorophyll pigment but in less quantity, since it has only a functional allele coding for a key enzyme involved in the chlorophyll pathway
