Answer:
D. The sympathetic system prepares the body for stress and activity and the parasympathetic system prepares the body for rest.
Explanation:
- Sympathetic and Parasympathetic nervous system are two divisions of autonomic nervous system.
- Acetylcholine is a common neurotransmitter released by preganglionic neurons of both systems.
- The post Ganglionic neurons of these two systems release different neurotransmitter.
- The sympathetic nervous system is concerned with 'fight and flight response'
- The parasympathetic nervous system is concerned with 'rest and digest ' response.
Answer: to gain energy for the cell
explanation:
Cellular respiration is the process through which cells convert sugars into energy. To create ATP and other forms of energy to power cellular reactions, cells require fuel and an electron acceptor which drives the chemical process of turning energy into a useable form.
Answer:
"Viral reverse transcriptase to make a DNA copy that is integrated into the host genome and then host RNA polymerase transcribes it is a true statement.
Explanation:
The virus is an infectious agent which is not considered living either considered non- living. The virus particles contain the genetic material that determines the trait of a virus in the form of either DNA or RNA.
The virus which contains the RNA replicates themselves by fist converting their RNA into DNA by reverse transcriptase enzyme. Once the DNA is made, the DNA is incorporated in the genome of the host and the machinery of the host performs the replication, transcription and translation.
Thus, the selected option is true.
