Answer:

False

Explanation:

It is the stratosphere layer of earth that protect us from harmful UV radiation. Basically ozone gas protects earth from UV radiation and nearly 90% of the ozone in atmosphere is found in the stratosphere at an altitude of 16 and 48 kilometers above the Earth's surface.

Ozone is found in a concentrated form in stratosphere only. This ozone has a tendency to absorb ultraviolet light from the Sun and protect the earth from the harmful effects of UV radiation.

Thus, it can be said that it is the stratosphere and not the troposphere that protects the Earth from UV radiation coming from the Sun

Answer:

b. diffusion and osmosis across semi-permeable membranes

Explanation:

ATP (adenosine triphosphate) is a high energy carrying molecule in the system of living organisms. It posseses the ability to store and release energy for use by organisms during biochemical activities. However, some processes do not require ATP to occur and are called PASSIVE TRANSPORT while those that require energy (ATP) are called ACTIVE TRANSPORT.

In the above options, the processes listed as follows require ATP to occur:

- The active transport of glucose from the small intestine to the blood

- The movement of the flagella of sperm for motility

- Exocytosis of waste substances across a semi-permeable membrane

However, the diffusion and osmosis across semi-permeable membranes, which is a passive transport does not require ATP.
