The host cells that viruses can infect are determined
by the ____________
a. receptors on the host cells
b. concentration of host cells in vicinity
c. DNA in host cells
d. proximity of host cells
viruses infect the cells by injecting their genetic material into the cell or the virus is endocytosed ino the cell, for these proces to occur virus has to bind to the cell surface, viruses use receptors or proteins on the cell surface to bind to the cell so the answer is a) receptors on the host cells

What best describes whether a virus is likely to infect a particular cell? Group of answer choices (A) Viruses infect the first cells they encounter. (B) A virus will only infect host cells with the correct surface receptors. (C) If a host cell is weakened, viruses are likely to infect it. (D) The initial choice is random but once a cell type is chosen it becomes the preferred host.
