Answer:

Mutation, fertilization, meiosis are different mechanisms by which changes can occur in the genome.

Explanation:

There are several process which is responsible for causing change in the genome of the species which results in the evolution of that species. Some of these processes are:

1. Mutation: In mutation, some nucleotide sequences get change and this change can occur due to frameshift, addition, deletion or any other process. This change in nucleotide can be seen in phenotype and helps in the evolution of the species.

2. Fertilization: During fertilization mixing of the genome of two individual takes place which results in producing a genetically distinct offspring which contains variation. So as the offspring is genetically different it can contain new alleles that can help the individual to survive in the changing environment.

Lana71 [14]

The correct answer is B. S-curve

Explanation

There are two models of population growth. One of them is the J-curve in which the population grows constantly without stabilizing, forming a J-shaped graph. Second, the S-curve is a model in which the population grows to a point, and from there it stabilizes, forming an S-shaped graph. According to the above, bacteria that divide rapidly until they run out of space and their growth slows down stabilizing the size of their population has an S curve model because the population does not grow unlimitedly but stabilized under specific circumstances. So, the correct answer is B. S-curve

Answer:

It's possible.

Explanation:

It said if they were nearly as smart as humans. They never said if they were as capable as Humans. Naturally, some would be smarter than others so some might be able to live here but others might have to have their own country. So, it is likely that some Neanderthals will be able to live in modern society, though not all.
