Explanation:

Small and nonpolar (hydrophobic) molecules can freely pass through the membrane, but charged ions and large molecules such as proteins and sugars are barred passage.

Nonpolar and small polar molecules can pass through the cell membrane, so they diffuse across it in response to concentration gradients.

Over 95% of incoming UV-B radiation is absorbed in the stratosphere. Please select the best answer from the choices provided
kramer

Answer:

True

Explanation:

The stratosphere is the layer of the earth’s atmosphere which is above the troposphere and below the mesosphere.

The stratosphere contains about 90 percent of the ozone layer. The stratosphere is made up of ozone layers which helps in the absorption of about 95 percent of the ultraviolet rays from the sun and converting to heat.

This is the reason why depletion of the ozone layer found in the stratosphere gives rise to global warming.
