Answer:
The correct answer is option D. "generally is of higher velocity, although it is masked by reduced turbulence".
Explanation:
In most rivers, the downstream portion is both wider and deeper than the upstream portion. This means that there is more water in the downstream portion, which in consequence results in the river having a higher velocity. However, this is masked by a reduced turbulence since a higher amount of water tend to overcome more easily all the obstacles that can generate friction.

Explanation:
Answer:
- Oxygen
- The body cells
- Producing energy
Explanation:
We breathe in oxygen from the external environment. Oxygen passes into our lungs and is passed into the blood capilaries. Here it is carried to all the cells throughout the body.
It diffuses into the cells and is necessary for the final stages of energy production by aerobic respiration. Therefore, it is necessary for powering all cellular processes.
Answer:
<em>It acts as a catalyst, lowing the activation energy and speeding up a reaction.</em>
Explanation:
The acetaldehyde alcohol dehydrogenase is used to turn acetaldehyde to ethanol.
In the end it releases 2ATP. Yet it has not given energy in the reaction under any conditions to carry it to fruition.
This merely decreases the reaction's activation energy and favors its operation within physiological circumstances.
Answer:
This is known as Phenotypic plasticity, the artic fox has the advantage of being able able to hunt rodents, birds and fish
Explanation:
Phenotypic plasticity can be explained as the changes in the behavior, morphology, physiology of an organism such as the artic fox in response to their unique habitat. It tells us how the artic fox is able to cope with the variations in it's environment.
Their natural hues helps them to blend into snow and ice since it is white. When there's a change in season, their fur or coat also changes as well to a brown or grey color that gives it cover when it is among rocks and plants.
These colorings gives them an advantage and help them to hunt rodents, birds and fishes.
