Answer:
The correct answer is "The "host range" for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach".
Explanation:
The missing option of this question is the one that is correct, which is "The "host range" for a virus is determined by the presence or absence of particular components on the surface of a host cell that are required for the virus to attach". A virus is able to infect by recognizing particular components that are present in the surface of the host cell. If this components are absent in the cell, the virus is not able to infect it. Therefore, the "host range" is determined by the presence or absence of this particular components.
It depends on the cell type. If it's a tissue cell, it will divide into 2 daughter cells through the mitosis process. If it's a gamete cell, it will divide through meiosis into 4 daughter cells.
