Correct Answer: B. to provide essential service for the people at a low cost

Correct Answer: D) endosperm

Explanation

In maize grain, there is a structure that stores food. The question is asking which structure performs this function. The options are radicle, embryo, cytoplasm, and endosperm. Radicle is the embryonic root of the plant, while embryo is the young developing plant enclosed in the seed. Cytoplasm is the fluid inside the cell membrane that contains organelles and other components. The correct answer to this question is option D, endosperm. The endosperm is a tissue that is formed inside the seed after fertilization. Its main function is to provide nutrition to the developing embryo. In maize, the endosperm is the largest structure in the seed and is the primary storage tissue for food reserves such as starch and proteins. Understanding the different structures and their functions in the seed is important in the study of plant growth and development. For more information, please see the recommended textbooks.

Correct Answer: B. 37.9

Explanation

Another word for mean is average. To find the average of this set of numbers, add them up, then divide by the amount of numbers in the set. In this case there are 7 numbers in the set, meaning we will divide our answer by 7. (41+38+27+42+35+38+44)/7=265/7=37.9

Explanation

(a) Whenever there is a change in the magnetic flux linked with a circuit, an e.m.f. is induced, the strength of which is proportional to the rate of the change of the flux linked with the circuit. The direction of the induced current is always such as to oppose the change producing it.

As coil is rotating in the magnetic field, an e.m.f which is due to the changing flux induces between its terminals. The e.m.f. varies from maximum when the coil is horizontal to minimum when the coil is vertical at which position connections between brushes and terminals of coil are changed by commutator. This ensures that current continues to flow in the same direction.

(c) – By increasing the number of turns – Winding the coil on the soft iron core – Increasing the strength of the magnet – turning the coil faster.
