1. plants in floodplains often get covered by water during floods. some plants survive the floods because they can continue photosynthesis underwater. however, the plants’ rates of photosynthesis are much lower underwater than above water. which of the following to explain why the rates of photosynthesis are lower underwater than above water? a. there is too much oxygen in the water b. there is no carbon dioxide in the water. c. the chloroplasts do not function underwater. d. the available light is less intense underwater

The answer is; D

As the sunlight changes media from the atmosphere into the water, some of it is reflected back while the rest is refracted and diffused by the water. The deeper the water column the higher the diffusion. Therefore, leaves under water receive lower sunlight intensity hence slowing down the rate of photosynthesis.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

answer: - b cells

explanation: -

so, the b cells mediate their action by identifying the antigens present on the surface of the pathogens and then producing antibodies in return to mediate its effect.
