What is unique about the cells that are created at the end of meiosis II? O They contain half the genetic material of their mother cells, and they become gametes.
O They contain twice the genetic material as their mother cells, and they become gametes.
O They contain twice the genetic material as their mother cells, and they become skin.
O They contain half the genetic material of their mother cells, and they become skin cells.

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.

explanation:

it provides an alternative energy pathway for the reaction to proceed.

a catalyst is a substance that speeds up the rate of a chemical reaction but is not consumed during the course of the reaction.

catalysts increase the rate of reaction without being used up. they do this by lowering the activation energy needed. with a catalyst, more collisions result in a reaction, so the rate of reaction increases. different reactions need different catalysts.

a catalyst works by providing an alternative reaction pathway to the reaction product. the rate of the reaction is increased as this alternative route has a lower activation energy than the reaction route not mediated by the catalyst.

its b. greenhouse gasses trap uv rays for heat so that the plants stay alive.
