Introduction:
The viruses are small biological infectious agents that can replicate inside the cells of other living organisms only. They are simple particles that require a host cell to replicate and survive.

Answer to Problem 1TYK
Correct answer:
The host cells provide ATP (adenosine triphosphate),
Explanation of Solution
Explanation/Justification for the correct answer:
Option (d) is given as all of the above. The viruses cannot make their own ATP, nucleotides, amino acids, and ribosomes. The virus cannot synthesize their own proteins. The virus enters the host cell to survive. The host cell provides the energy (ATP) to the viruses inhabiting it. It also provides nucleotides for
Explanation for the incorrect answers:
Option (a) is given as nucleotides and amino acids. Host cell provides amino acids as well as nucleotides for viral growth and development. The entities like ATP and ribosomes are also provided by the host cell to the virus. So, it is an incorrect option.
Option (b) is given as ribosomes. Host cell provides ribosomes to the viruses that serve as the site for protein synthesis. Nucleotides, amino acids, and ATP are also provided by the host cell. So, it is an incorrect option.
Option (c) is given as ATP. The ATP is provided by the host cell to the viruses to carry out various cellular activities. Nucleotides, amino acids, as well as ribosomes are also provided by the host cell. So, it is an incorrect option.
Hence, options (a), (b), and (c) are incorrect.
Therefore, it can be concluded that the host cells provide energy, proteins, nucleotides, ribosomes, and amino acids to the viruses for their development and growth.
