Somatic sensory division of the pns is responsible.
<h3>
Somatic sensory division</h3>
A component of the peripheral nervous system known as the somatic nervous system (SNS) or somatic sensory division, sometimes known as the voluntary nervous system, is responsible for the voluntary control of skeletal muscle-based motions of the body.
The somatic sensory division is made up of motor nerves with efferent nerve fibers that relay motor commands from the central nervous system (CNS) to cause muscle contraction and sensory nerves carrying afferent nerve fibers that relay feeling from the body to the CNS.
Each voluntary muscle system in the body as well as the process of voluntary reflex arcs are under the direction of the somatic sensory division.
The top cell bodies of motor neurons are the starting point of the basic sequence by which nerve signals travel within the efferent somatic sensory division.

The question is incomplete as the options are not provided which are:
RNA replicase is present in the viral capsid.
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
The new bacteriophage is a retrovirus.
The RNA genome is of the plus sense.
Answer:
The RNA genome is of the plus sense and RNA replicase is present in the viral capsid.
Explanation:
The bacteriophage is the virus particles which are composed of the genetic material enclosed in the Capsid protein. The Bacteriophage virus infects the bacteria and uses their replication machinery to replicate themselves.
In the given question, all the proteins along with RNA for translation or ribosomes is provided. The single-stranded RNA is first their genome copied by the RNA replicase and the positive strand, therefore, acts as the mRNA. This mRNA is then translated into the protein sequence and a new virion is produced.
Thus, the selected option is correct.
The advantage of a phototropism is that the plants grows in the direction of the sunlight and not into a shadowed direction where it would get less light
Answer:
Explanation:
Enzymes are biological catalysts; catalysts are substances that increase the rate of chemical reactions without being used up (BBC, 2010), without these catalysts it would take an extremely long time for these reactions to take place. The enzyme used in this particular experiment was pepsin; pepsin is a zymogen of pepsinogen. Pepsinogen is activated by hydrochloric acid, which is released from parietal cells in the stomach lining. The hormone gastrin and the vagus nerve trigger the release of both pepsinogen and hydrochloric acid from the stomach lining when food is ingested. Hydrochloric acid creates an acidic environment, which allows pepsinogen to unfold and cleave itself in an autocatalytic fashion, generating pepsin. (Life Science Network, 2010)
A lot can be learnt about enzymes by studying the rate of enzyme catalyzed reactions, these rates of reaction can be studied in various ways. In this experiment, using a range of different temperatures, the enzyme pepsin will be mixed with egg albumen. This is high in protein and bound to the dye Coomassie blue to gain a light absorbance reading using a spectrophotometer and in effect see how much protein has been digested by the pepsin.
