Correct option C) inactivation of the XIST gene on the X chromosome derived from the male parent.
Embryonic development in females and one of the X chromosomes is rand come and permanently inactivated is cells than egg cells. The phenomenon is called X- inactivation or lyonization.
X- inactivation which is called lhyonization , is process by which one of the copies of Chromosome inactivated in therian female mammals. The inactivated X- chromosome is silenced by being packaged into a transcriptionally inactive structure called hetero chromatin.
In case of both X chromosomes and all of their genes were to be activate in women and they would have twice as many copies of the opposite that they have in men.

They are like the animals who fly. They do have built-in mechanisms that enable them to go up and down in the water. The downward pull is the gravity and the upward push of the buoyancy. The force of the buoyancy is equal to the weight of the fluid displaced by that object. So fishes use their swim bladder for them to be able to ascend.

Answer:
The heat from the sun warms the water in the lake which evaporates and turns into water vapours. The water in the tree also rises into the atmosphere through a process, transpiration.
The water vapours rise into the atmosphere and forms clouds.
The water vapours in the clouds than condense into liquid water. Soon they'll get heavy and the water will fall down as rain, sleet, or snow.
Some of the rainwater sinks into the ground and is taken in by the roots of trees and plants.
This process keeps going on and on, and the water keeps shifting between the lake, tree and the sky.
Answer:
False
Explanation:
When a muscle or group of muscles were able to withstand consecutive repeated contractions in opposition to a resistance for a longer period of time it is known as Muscular Endurance.
Muscular endurance relate the ability for the body to work for an enlarged and increased rate of time.
On the other hand, Muscular Strength implies the total amount of force a muscle or group of muscles can generate with a single maximum effort. The muscular strength can be measured and be determined during muscular contractions.
Hence, from this explanation, it clearly depicts that Muscular strength refers to the maximum amount of force a muscle group can generate.
