With reference to the virus ,consider the following statements: It is ...
Explanation:
Viruses are a type of microbe that are quite different from bacteria, fungi or protists. They are much smaller than bacteria and are not considered living organisms as they cannot replicate without a host cell. Let us examine the given statements:
Statement 1: It is a microbe consisting of a Deoxyribonucleic acid or Ribonucleic acid surrounded by a protein coat.
Yes, this statement is correct. Viruses are composed of genetic material (DNA or RNA) surrounded by a protein coat called a capsid. Some viruses also have an outer envelope made of lipids.
Statement 2: It cannot replicate alone and require a host cell to make copies of itself.
This statement is also correct. Viruses do not have the machinery to replicate on their own. They must infect a host cell and hijack its cellular machinery to produce new copies of the virus. This process can cause harm to the host cell and can lead to disease.
Therefore, both statements are correct and the correct answer is option C (Both 1 and 2).

With reference to the virus ,consider the following statements: It is ...
Recently, European regulators have approved the region's first vaccine for respiratory syncytial virus (RSV).
- Respiratory syncytial virus is a common respiratory virus that usually causes mild, cold-like symptoms.
- It is serious infects infants and older adults.
- It is the most common cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia in children younger than 1 year of age in the United States.
- The complex molecular structure of the virus and safety concerns with previous vaccine attempts had stymied efforts to successfully develop a shot.
What is virus?
- A virus is an infectious microbe consisting of a segment of nucleic acid (either DNA or RNA) surrounded by a protein coat.
- It cannot replicate alone; instead, it must infect cells and use components of the host cell to make copies of itself.
Hence both statements are correct.
