Materials can move across capillary walls by .a. reabsorption. b. diffusion. c. filtration. d. All of the answers are correct. e. None of the answers is correct.

The correct option is D) All of the answers are correct.

Explanation:

The walls of the capillaries are thin due to which the processes of diffusion and filtration becomes lot easier in them. Gases such as oxygen and carbon dioxide cross the capillary walls through diffusion processes. As the walls of the capillaries are much thinner than that of veins and arteries hence. the processes of filtration and re absorption occur easily through them.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

that is wrong, its not thymus.
