The pleura is a connective tissue sheath that covers which of the following organs?

A. Lung

B. Heart

C. Spleen

D. Liver

Answer Explanation:

The pleura is a thin membrane that surrounds the lungs and lines the chest cavity. It protects the lungs from friction and infection, and helps them expand and contract during breathing. The other organs listed are not covered by the pleura, but by other types of connective tissue sheaths, such as the pericardium for the heart, the peritoneum for the spleen and liver, and the mesentery for the intestines.

Therefore, the Correct Answer is A.

B. Cancerous and normal cells share genetic sequences.

C. Viruses and cancer cells both replicate rapidly.

Answer Explanation

Viruses can cause cancer by inserting their genetic material into the host cell's DNA, disrupting the normal regulation of cell division and growth. This process is called viral oncogenesis. Some viruses, such as human papillomavirus (HPV) and hepatitis B virus (HBV), are known to cause certain types of cancer in humans. Genes that regulate cell division are found in some viruses. This statement implies that some viruses have the ability to alter the host cell's genes and induce cancerous changes.
