Convection transfers heat within the atmosphere and ocean. Therefore, the correct option is A.
The process of convection involves the transport of heat through the movement of liquids such as air or water. Convection is an important mechanism for heat transfer in the atmosphere and ocean. Because of its low density, warm air or water rises, creating vertical currents that carry heat upward.
The convection cycle is complete when the cooler air or water is replaced by the rising warm air or water. This process affects weather patterns, ocean currents, and climate dynamics by controlling temperature trends in the atmosphere and water.
Therefore, the correct option is A.

d. the centrosomes of plants do not replicate prior to cell division.
Only a living organism exhibits all of the characteristics of life.
Answer:
True
Explanation:
All living things such as plant, animal, human being and micro-organisms on this planet are able to exhibit all characteristics of life such as breathing, movement , reproduction, sensation, growth, excretion, nutrition etc. on their own. They are made of living cells that specializes themselves to perform specific task.
Non living things are not able to exhibit all the above characteristics of living things as they are made up of dead molecules/atoms.
Thus, the given statement is true.
