There is considerable evidence that Coronavirus 19 arose in nonhuman mammals, such as
pandolins or bats. Which of the following is the MOST PLAUSIBLE explanation for why no
birds have been implicated as vectors? Question 24 options: The virus relies on the adaptive
immune system, and birds have only an innate immune system. Birds are ectotherms, and the
virus requires high temperatures to reproduce. The proteins that enable the virus to bind to and
infect cells may be different in mammals and birds. The layer of feathers may prevents this virus
from entering across the skin..
