Answer:
A viral infection is simply caused by a virus. Antibiotics are used to treat infections caused by bacteria. Hence, antibiotics are not capable of killing viruses. Viruses, on the other hand, are structured differently compared to bacteria and survive and replicate in different ways too. A virus is surrounded by a protective protein coat and not a cell wall that can essentially, be attacked by an antibiotic. Furthermore, in contrast to bacteria, viruses move into our body's cells, rather than attack them from the outside. As a result of all these differences, antibiotics may not be used to treat viral infections.

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.
It’s a type of Nucleotide
