Answer:
The correct answer is "The frequency of the B allele increased due to the selective pressures of the environment".
Explanation:
The missing part of the question is "Which of the following could best explain the increase in the frequency of the B allele in the population after five years?" at which the answer is "The frequency of the B allele increased due to the selective pressures of the environment".
In this study, the allelic frequency for black fur (B) in eastern gray squirrels Sciurus carolinensis changed from B=0.4 to B=0.6 within a lapse of five years. This increase is explained by the effect of selective pressures of the environment. For instance, is likely that new predators were more likely to detect squirrels with gray fur over black fur, or changes in the landscape benefited the black fur squirrels camouflage.
The correct answer is: A. Species A had more massive jaw muscles than species.
Massive jaw muscles are correlated to more primitive diet. It is believed that shrinking jaw muscles is part of the evolution. It is the way for making the space for a bigger brain.

<h3><u>Explanation</u>:</h3>
Sir,
I am very sad to inform you that the town of Hariharanpur is suffering from continuous erosion for the last 3 years. Even after having proper knowledge about this fact, you being the mayor, are not taking any charge of this situation.
The town is situated just by the side of River Ganges which makes it's soil full of moisture. Along with the repeated deforestation and tree cutting for urbanisation, the smallest of the rain falls are also eroding a lot of soils. This can lead to severe landslides in river Ganges with severe loss of properties as well as loss of lives too.
So i request you to start embanking the river as well as to start planting new trees to save the town from getting lost under Ganges.
Thanking you,
XYZ.

The correct answer is - It has to act together with the nervous system mainly with other systems that assist in rock climbing.
Explanation:
Rock climbing is a physical activity or sport that could practice indoor or outdoor with mountains. It is a sport that requires physical and mental strength as it requires muscle strength, coordination, or balance, agility, endurance, and mental control over body and mind.
Muscular systems involve pulling the weight of an individual towards and leg muscles to hold whereas the nervous system controls or maintain the actions of muscles and also helps in balance the body of the climber. This neuromuscular set helps in maintains the muscle's tonicity in order to execute the action of climbing.
Other than these two main body systems there are cardiovascular system, circulatory system and respiratory system also helps in providing the conditions like increase oxygen input, high heartbeat, and more.
