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 D
Explanation
When viruses cause an infection, they spread their DNA, affecting healthy cells’ genetic makeup and potentially causing them to turn into cancer.
For instance, HPV infections cause the virus’ DNA to combine with the host’s DNA, disrupting the normal function of cells.
Choice A is not correct because cancerous and normal cells sharing genetic sequences do not support the hypothesis that viruses can cause cancer.
Choice B is not correct because cellular DNA having sequences related to viral sequences does not support the hypothesis that viruses can cause cancer.
Choice C is not correct because viruses and cancer cells both replicating rapidly do not support the hypothesis that viruses can cause cancer.

The Golgi apparatus is an organelle found in eukaryotic cells that is involved in modifying, sorting, and packaging proteins and lipids for transport to other parts of the cell or to be secreted outside the cell.
Choice C is incorrect because chloroplasts are not present in prokaryotic cells.
Chloroplasts are organelles found in plant cells and some algae that are responsible for photosynthesis.
Choice D is incorrect because the endoplasmic reticulum is not present in prokaryotic cells.
The endoplasmic reticulum is an organelle found in eukaryotic cells that is involved in protein synthesis and lipid metabolism.
