Answer:
The stages of most stars life in order are: A Protostar, Main Sequence, Red Giant B Protostar, Main Sequence, Red Dwarf C Main Sequence, Red Dwarf, Protostar D Red Giant, Main Sequence, Protostar E Nebula, Protostar, Red Dwarf. 2 What does a protostar have to do to become a star? A Nuclear fusion in its core. B Nuclear fission in its core.
The fertilized cell that results is referred to as a zygote. A zygote is diploid cell, which means that it has twice the number of chromosomes as a gamete

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:
