A population of chimpanzees was separated when the forest that they lived in had a section cut down and a town was built. After a long period of time, the chimpanzees came back into contact but were incapable of breeding. Which of the following best describes the process that occurred?a. adaptation
b. speciation
c. convergent selection
d. stabilizing selection

Answers

Answer 1

Answer:

Speciation occurs when a population suffers divergence. Genetic flow is interrupted between the new groups that keep reproducing and going through mutations. Reproductive isolation emerges. Option B. Speciation.

Speciation

Occurs when the original population is divided into two or more groups and each group is exposed to different environments.

Each group reproduces for many generations, going through many changes or mutations.

These changes will depend on each group's environment and its ecological pressures.

Pressures act on individuals and make them adapt to the new environmental conditions.

Generation after generation, the genotype of individuals will increase the fitness to survive and reproduce.

The fixation of mutations will increase the difference among both groups, up to the diverging point into two new species.

Allopatric speciation

There are different types of speciation. One of them is Allopatric speciation.

Allopatric speciation refers to the geographical separation of a continuous genetic population, originating two or more new geographicallyisolated groups.

During these events of speciation, emerging new barriers impede genetic flow between groups. The two new populations that are separated can not get together and mate anymore.

These barriers might be geographical or ecological.

After the emergence of the barrier, the two populations evolved separately in different new species.

Two different species that evolved in allopatry might meet again in secondary contact if the barrier that separated them, disappears. However, they will not be able to mate and reproduce due to prezygotic and postzygotic reproductiveisolation.

The exposed example is a case of speciation, in which the chimpanzees' habitat was fragmented and a town was built.

The town acts as the barrier between the two diverged groups, impeding them to meet.

Genetic flow is interrupted and each group keeps reproducing separately, and mutating, leading to genetic changes and reproductive isolation.

After a long period of time, the chimpanzees came back into contact but were incapable of breeding.

This process is speciation. Option B.

Answer 2

Answer: The definition of a biological species is that they will only breed with members of their own species. If the two populations of chimps will no longer interbreed, then they are considered separate species = speciation.

B. Speciation

In 1831, Charles Darwin visited the Galapagos Islands. While observing the giant land tortoises that lived on these islands, Darwin noted that the shape of the tortoise shell varied depending on which island the tortoise lived. Tortoises on one island had round shells, for example, whereas tortoises on a neighboring island had more flattened, saddle-shaped shells. Which statement BEST summarizes Darwin's explanation for these differences?A) Random mutations caused the shape of the shells to fluctuate periodically. B) The shape of the tortoise shell varied because the predators on the islands were different. C) The particular shape of the shell was best suited for the island on which the tortoise was living. D) Tortoises who used their shells in special ways caused the shells to become larger, rounder, or flatter.

Suppose you use a microscope to look at a cell from the leaf of a tree. What structure will you see that would not be found in a cell from your fingernail? A. mitochondria B. cilia C. cell wall D. ribosomes

Answers

Cell walls made of cellulose are present in plant cells. Human cells (skin, fingernails, muscle, etc.) do not have cell walls. Both plant and human fingernail cells have ribosomes and mitochondria. There are no cilia on either of the cells. Therefore, answer C is correct. Hope this helps! :)
