Ariver changes course, so a population of mice is subdivided into two populations. the forest on the eastern side of the stream contains a land predator that is absent on the western side of the stream. which outcome will most likely occur in the mice populations over many generations? a. mice on the western side of the stream will have better camouflage. b. mice on the eastern side of the stream will have a different number of chromosomes. c. the two groups of mice will become different species. d. the two groups of mice will continue to eat the same food.

Over many generations, the two groups of mice will become different species.

When a population of organisms of the same species becomes isolated geographically, each population will take different paths towards adapting to their respective environmental changes.

Thus, over a period of time, each population would have developed different mechanisms to cope with their changing environmental factors leading to them becoming different species.

In other words, geographical isolation leads to speciation.

C. The two groups of mice will become different species.

Explanation:

In the question above, we see that a population of mice was geographically separated by a river. From a river side, the population of mice will have to face a predator, however the population that stayed on the other side will not have this problem, since the predator does not exist in its reaction.

Due to the presence of this predator, the two populations of mice will have to promote a different evolution and adaptation to each other, which may give rise to different species, since the survival strategies may modify this species of mice.

me i can you if you would like.

you are certainly talking about this picture:

a: is the label of the white square, it is showing the  replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication 

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes  the dna with the dna template and increases  the processivity of the enzyme. ==>   stops polymerase from falling off the  template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built  in the opposite sense of the helicase, so dna will be built in fragments ==> built  fragments from 5' to 3 joins

and finally f: is the enzyme that builds  the new dna strand (dna polymerase) ==>   adds nucleotides to make a new dna helix.
