Expert Solution & Answer

Summary Introduction

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), nucleotides, amino acids, and ribosomes to the viruses for their growth and development.

Explanation of Solution

Explanation/Justification for the correct answer:

Option (d) is given as all of the above. They 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 in it. It also provides nucleotides for nucleic acid synthesis, and amino acids and ribosomes for the protein synthesis in the viruses. Hence, Option (d) is correct.

Explanation for the incorrect answer:

Host cell provides all the three entities ATP, nucleotides, and amino acids for viral growth and development. It does not provide solely ATP, nucleotides and amino acids, and ribosomes. Hence, all the three options (a), (b), and (c) are incorrect.

Conclusion

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.
