Option B. DNA polymerase, is the correct answer.

Explanation:

DNA polymerase is a material which is responsible for checking errors in the DNA. Sometimes, errors occurs when the nucleotides is entered into the growing strand. When the error occurs, it can be corrected by DNA polymerase or another DNA containing enzyme. Sometimes, DNA is repaired and sometimes dealth occurs and removed from the body.

B. DNA polymerase

Explanation: DNA polymerase is an enzyme that catalyzes the addition of free nucleotides to the primer during replication. DNA polymerase also has a 3'->5' exonuclease activity which double-checks each nucleotide after it is added. The exonuclease activity of the DNA polymerase permits it to remove a newly added mismatched nucleotide. When the polymerase adds a wrong nucleotide, movement of the enzyme to the point where the next nucleotide will be added is halted, this 3'->5' exonuclease activity removes the mismatched nucleotide so that replication can continue.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
