Which of the following statement is correct?

a.pollination can take place without
fertilization

b. fertilization can take place without pollination

c. pollination and fertilization are the same thing

d.pollination and fertilization must occur at the same time

A is the correct answer. Pollination is what keep the plants alive, without it there would be nothing to fertilize. Fertilizing can help keep plants healthy and can help them grow but is not necessary for their survival.

Explanation:

There are three ways heat is transferred into and through the atmosphere.

radiation. conduction. convection.

Radiation

Radiation is the transfer of heat energy through space by electromagnetic radiation.If you have stood in front of a fireplace or near a campfire, you have felt the heat transfer known as radiation. The side of your body nearest the fire warms, while your other side remains unaffected by the heat. Although you are surrounded by air, the air has nothing to do with this transfer of heat. Heat lamps, that keep food warm, work in the same way.

Conduction

Welding iron is transferring heat by conduction

Conduction is the transfer of heat energy from one substance to another or within a substance. Have you ever left a metal spoon in a pot of soup being heated on a stove? After a short time, the handle of the spoon will become hot.This is due to transfer of heat energy from molecule to molecule or from atom to atom. Also, when objects are welded together, the metal becomes hot (the orange-red glow) by the transfer of heat from an arc.

Convection

convection is the transfer of heat energy in a fluid. This type of heating is most commonly seen in the kitchen with a boiling liquid.

Air in the atmosphere acts as a fluid. The sun's radiation strikes the ground, thus warming the rocks. As the rock's temperature rises due to conduction, heat energy is released into the atmosphere, forming a bubble of air which is warmer than the surrounding air. This bubble of air rises into the atmosphere. As it rises, the bubble cools with the heat contained in the bubble moving into the atmosphere
