Biology MCQs

Notes:
Vernalization is the induction of a plant’s flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually flower.

Notes:
A camel’s hump does not hold water at all – it actually stores fat. The camel uses it as nourishment when food is scarce. If a camel uses the fat inside the hump, the hump will become limp and droop down. The hump is not used for water storage, but camels can go for long periods of time without water.

Notes:
Hypothalamus acts as the thermostat of human body as it regulates the body temperature as the same way a thermostat controls the room temperature. It is located in the skull of the human body.

Notes:
Carbohydrate is a biomolecule that is found in the most abundance on earth. Carbohydrates are mostly produced by green plant cells, algae and some bacteria.

Notes:
Herpes, Influenza and Measles viruses are most susceptible to chloroform.

Notes:
In plants, water acts as the channel through which gamete transfer takes place.

Notes:
Monotrichous bacteria have a single flagellum. Lophotrichous bacteria have multiple flagella located at the same location on bacterial surfaces that work together to steer the bacteria in the same direction.
