Answer:
The correct answer is A. energy was required to produce the concentration gradient.
Explanation:
There are two types of transport through which a molecule moves in and out of the cell and these are active transport and passive transport. In passive transport, the molecule moves without the help of energy because they move down there concentration. So in passive transport, if concentration gradient changes then passive transport will take place.
In active transport, the molecule move against their concentration gradient with the help of energy or ATP. So in passive transport, the concentration of molecule can be high in the cell because its transport occurred against the gradient with the help of energy. So the correct answer is A.

Explanation:
<span>The simplest, yet most effective method of preventing the spread of an infectious disease is to </span>wash your hands in between patient contacts.
Washing hands regularly in the right moment will cause the pathogen harder to spread, thus making it less likely to infect other people.
1. Sedimentary-formed from particles of sand, shells, pebbles, and other fragments. Generally soft and breaks apart easily.
2. Metamorphic-formed under the surface of earth from the change from the heat and pressure. These rocks will have a shinny crystal like shine to them.
3. Igneous-formed when the magma cools down and hardens. Won't have a shinny look to it. Sometimes will have tiny holes in them.
