Which of the following are the two major parts of the nervous system?
Autonomic nervous system and somatic nervous system.
Peripheral nervous system and somatic nervous system.
Peripheral nervous system and central nervous system.
Autonomic nervous system and central nervous system.
The Correct Answer is C
The two major parts of the nervous system are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS).
The CNS comprises the brain and spinal cord and acts as the integration and command centre of the body.
The PNS represents the conduit between the CNS and the body and is further subdivided into the somatic nervous system (SNS) and the autonomic nervous system (ANS).
Choice A is incorrect because it only mentions two subdivisions of the PNS: the autonomic nervous system (ANS) and the somatic nervous system (SNS).
Choice B is incorrect because it only mentions one major part of the nervous system, the PNS, and one subdivision of it, the SNS.
Choice D is incorrect because it only mentions one major part of the nervous system, the CNS, and one subdivision of the PNS, the ANS.

Correct Answer is B
Explanation
Reverse transcriptase is a virus-specific enzyme that transcribes an RNA template to DNA1.
This allows the AIDS virus, which contains RNA, to insert viral DNA into the DNA of a host cell after the AIDS virus enters the cell.
Choice A, The phospholipids found on the envelope of the virus, is not the correct answer because phospholipids are a major component of cell membranes and do not play a direct role in inserting viral DNA into the DNA of a host cell.
Choice C, Receptor proteins located on the surface of the virus, is not the correct answer because receptor proteins located on the surface of the virus play a role in attachment and fusion of HIV virons to host cells2, but do not play a direct role in inserting viral DNA into the DNA of a host cell.
Choice D, The protein that makes up the capsid of the virus, is not the correct answer because capsid is the outer protein shell of a virus and does not play a direct role in inserting viral DNA into the DNA of a host cell.
Correct Answer is D
Explanation
Genes are segments of DNA that encode the information for making proteins.
The sequence of nucleotides (As, Ts, Cs, and Gs) in a gene determines the amino acid sequence of the protein. DNA sequencing is the process of determining the sequence of nucleotides in a piece of DNA.
Choice A is incorrect because enzymes are proteins that catalyze chemical reactions, not DNA sequences. Choice B is incorrect because blood types are determined by the presence or absence of certain antigens on the surface of red blood cells, not by DNA sequences. Choice C is incorrect because hormones are chemical messengers that regulate various body functions, not DNA sequences.
