Carbon dioxide concentrations are expected to increase, because fossil fuel burning is expected to increase, because of an increase in agriculture and because more land will have to be cleared for increasing populations and agricultural use.
The correct answer is rapids and waterfalls.
Rapids refers to the segments of streams with extensively vigorous currents, various obstacles, and steps in their streambeds. A waterfall refers to a vertical drop in a stream bed. Both are the locations of vigorous erosion.
The rapids are generally produced where the resilient bedrock limits a stream to a narrow channel and forces an enhancement in the velocity of water.
On the other hand, waterfalls are produced where the fast-flowing water negotiates a geologic contact amid the more resilient and less resistant layers of rock, or through a fault, which has analogized distinct kinds of rocks. Or it can be said that waterfalls usually produce at the end of a series of rapids.
Answer:chain-link fence
Explanation:a cell membrane is partial permeable which means that it lets some substances through but not other.
You see, passive transport needs no energy. So that being said, it moves from areas with high concentration to areas with low concentration.
Hope that helps!
