Answer:
Uses each strand of a DNA molecule as a template for the creation of a new strand. (Option A)
Explanation:
DNA replication: It is defined as the uses of each strand of a DNA double helix act as a template for the creation of a new complementary strand. During the process of DNA replication, one leading strand (new strand) is made as a continuous piece and another lagging strand is made in small pieces.
DNA replication process, in addition to DNA polymerase, requires other enzymes such as DNA ligase, DNA helicase, DNA primase, and topoisomerase. DNA polymerase is the key molecule in the DNA replication, it is responsible for the synthesizing DNA. They help to add one by one nucleotide to the growing DNA chain and incorporating only those which are act as complementary to the template.
Using the theories of nervous system, we got it is true that inhibition of the sympathetic nervous system inhibits urination primarily by inhibiting the detrusor muscle.
Nervous system involves large number of mechanisms at the same time.
The parasympathetic nervous system stimulates the detrusor muscles to contract, causing the person to urinate. This sympathetic nervous system stimulates the contraction of the internal urethral sphincter, causing the person to hold the urine. Somatic efferent neurons stimulate contraction of the external urethral sphincter, which is the skeletal muscle.
Hence, inhibition of the sympathetic nervous system inhibits urination primarily by inhibiting the detrusor muscle is true.

I think the answer is A, I’m not sure tho
The skin has only 2 layers—epidermis and dermis. Hypodermis, if that’s what you have in mind as the third, isn’t considered part of the skin.
The epidermis is a barrier to infection, trauma, and water loss (dehydration); it’s important to our social interactions; and it’s the body’s largest sense organ. The dermis provides toughness and resistance to mechanical stress; provides blood vessels that come close to the epidermis and nourish it (but don’t enter it); contains a variety of sensory receptors for touch, heat, cold, pressure, and vibration; and is an arena of immune defense in which white blood cells can rally at a site of infection and fight off intruders.
