The host range of a virus is determined by A. whether the glycoproteins or capsid proteins on its surface recognize those of the
Marina CMI [18]

Answer:

A. whether the glycoproteins or capsid proteins on its surface recognize those of the host cells.

Explanation:

Virus has different surface proteins that are recognized by the receptors present on its host cell. The range of a virus is determined by the recognition of these proteins by the host cell.

The interaction between the receptor on the host cell and surface proteins on the viral capsid is important for viral genome entry in the host cell and to determine the range of the host cells.

If the surface protein of the virus is not able to bind to the receptor on any cell then the virus can not infect the cell. For example, the HIV virus infects only those cell which have CD4 receptors. So the right answer is A.

In landscapes dominated by low-infiltration capacity, what is the first step in erosion?
Oksana_A [137]
Low infiltration capacity means that the soil cannot absorb much water per volume. The first step in erosion in a landscape dominated by low-infiltration capacity is the raindrop splash. This is where raindrops displace the soil from their original place because the soil cannot absorb adequate amounts of water.
