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.

before, trains worked using the steam engine. thus, it uses heat so it is crucial to apply heat balance. the steam engine absorbs energy during the stage of boiling water. so, this is the endothermic reaction. when the steam is used to work the piston, it has to release this energy through running the train. the excess energy is released as an exhaust to the chimney. this is the exothermic process because it releases energy to the surroundings.
