General names for carbohydrates include sugars, starches, saccharide, and polysaccharides. They store energy in the form of starch (photosynthesis in plants) or glycogen (in animals and humans) and provide energy through metabolism pathways and cycles. Metabolism and combustion convert chemical energy into other forms of energy such as heat.

Correct Option: A

The pineal gland is a small endocrine gland in the vertebrate brain. It produces the serotonin derivative melatonin, a hormone that affects the modulation of wake/sleep patterns and seasonal functions. Its shape resembles a tiny pine cone (hence its name), and it is located near the centre of the brain.

Natural rubber is harvested mainly in the form of the latex from the rubber tree. The latex is a sticky, milky colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called “tapping”. The latex then is refined into rubber ready for commercial processing.
