Viruses do not have a nucleus, they cannot be recycled because they release their genetic code and that cannot be recovered unless they replicate and the problem with letting them replicate is that they have a likelihood of mutating and becoming something malicious. So by the power of deduction the correct answer is 3
Answer:
parasitism
mutualism
commensalism
Explanation:
Commensalism is defined as a relationship between two living organism in which one organism get benefits and the other organism neither benefit nor harm.

Hence, the correct answer is:
parasitism
mutualism
commensalism

Small pox vaccines can only be tested on humans, however Bc the flu can replicate in pigs, scientists can tests vaccines on pigs. Since there are two means in which it can spread, scientists must be aware of the genetic difference between humans and pigs and act accordingly. Influenza vaccines might have greater success rates Bc of their ability to test the efficiency of their vaccines on pigs in comparison to small pox vaccines which can only be tested on humans.
Hope this helps!
The answer is a haemoccult test. This test involves laboratory testing of three consecutive stool samples for the presence of blood which is invisible to the eye (occult blood). Presence of blood in the stool, however, does not necessarily mean that a person has colorectal cancer.
