Mention the river drainage through the river valley???

Answer 1

Throughout history humans have found it desirable to construct cities along streams. Streams are sources of water for consumption, agriculture, and industry. Streams provide transportation routes, energy, and a means of disposal of wastes. Stream valleys offer a relatively flat area for construction. But, human populations that live along streams also have the disadvantage that the flow of water in streams is never constant. High amounts of water flowing in streams often leads to flooding, and flooding is one of the more common and costly types of natural disasters.

A flood results when a stream runs out of its confines and submerges

Answer 2

Phloem is involved in the distribution of food to different parts of the plant. The transportation of food in phloem is an active process achieved by utilizing energy from ATP which helps in creating osmotic pressure that transports food against the gradient from the area of high concentration to low concentration.

So, the correct answer is option A.
