Study the population growth curves in the given below and answer the questions which follow: Which one of them is considered a more realistic one and why?

These questions consist of two statement each, printed as Assertion and Reason. While answering these questions, you are required to choose any one of the following four responses. A. If both Assertion and Reason are true and Reason is a correct explanation of the Assertion. B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion. C. If Assertion is true but Reason is false. D. If both Assertion and Reason are false. Assertion: In angiosperms the conduction of water is more efficient because their xylem has vessels. Reason: Conduction of water by vessel elements is an active process with energy supplied by xylem parenchyma rich in mitochondira.

Sanya has a piece of land which is in the shape of a rhombus (See Fig. ). She wants her one daughter and one son to work on the land and produce different crops to suffice the needs of their family. She divided the land in two parts by joining its opposite comers. If the perimeter of the land is 400 m and one of the diagonals is 160 m, how much area each of them will get to work on.
