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.

The feature of endocrine system that makes it distinctly different from the nervous system is that it uses hormones distributed through the bloodstream, option(A).

<h3>Why is endocrine system distinctly different from nervous system?</h3>

The biggest difference between these two is that the endocrine system uses hormones produced by glands into the bloodstream, whereas the nervous system uses electrical impulses to send signals through neurons.
The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are short-lived when compared to endocrine system.

Therefore, option(A) is the correct answer.

To know about differences between the two systems, refer:

Answer:

amino acids

Explanation:

A protease is an enzyme capable of catalyzing the breakdown of proteins into polypeptide fragments and single amino acids, which are the building block of proteins. Proteases act by breaking peptide bonds by a process called hydrolysis, a reaction where water molecules break down peptide bonds (hydro means water and lysis means split). Proteases can be classified depending on the catalytic residue into cysteine, serine, threonine, aspartic, glutamic and metalloproteases.

What is the purpose of the replication

stepan [7]

The purpose of the replication bubble is that it forms where replication is taking place (option A).

<h3>What is replication?</h3>

Replication is the process of producing replicas or duplicate of DNA or RNA molecules.

DNA replication is a very important process that occurs prior to cell division. During replication, the double stranded DNA is separated into two single strands.

Each copy called the leading and lagging strand becomes the template for the synthesis of new DNA strands.

However, a structure called replication bubble is a formed during the separation of two DNA strands by the helicase enzymes.

Therefore, the purpose of the replication bubble is that it forms where replication is taking place.
