Viruses depend on the host cells that they infect to reproduce. When found outside of host cells, viruses exist as a protein coat or capsid, sometimes enclosed within a membrane. An infected cell produces more viral protein and genetic material instead of its usual products.

Explanation:
Temporal isolation is a prezygotic barrier that is caused by the inability of two closely related species to interbreed as a result of differences in breeding season.
