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.
Answer:
Praying mantis cannibalism explained. When a female praying mantis bites the head off her sexual partner, it is probably not out of anger. ... The scientists tracked the flow of radioactive proteins through the bodies of the cannibalistic females, and through their eggs.
With ideal environmental factors, bacteria are able to reproduce at a very rapid pace.
<h3>Bacterial reproduction</h3>
Bacteria reproduce mainly by a single cell dividing into two, given the right condition. In order words, they reproduced by binary fission.
When environmental conditions are optimum, a typical bacterial cell can divide every 4 to 20 minutes depending on the species.
The time can become longer with sub-optimal environmental conditions.
