A doctor is performing a study under a very powerful microscope and records the following observations: Type of diet
None observed
Measure of growth
No change in size or mass
Amount of waste produced
0 micrograms
Type of reproduction
None observed
Which of the following is the doctor most likely observing?
A a fungus
B a virus
С a protist
Da bacterium

B.) a virus

Explanation:

I believe it's a virus because they typically cannot reproduce without a host, unlike bacterium, fungi, and protists, which can all reproduce asexually.

Biology is not my strong point, but after doing a bit of research, a virus should be the correct answer.

answers are:

lysogenic     viral dna merges with host cell dna

lysogenic     no symptoms

lytic               viral dna takes over

lysogenic     virus does not destroy host cell

lytic               virus destroys host cell

lytic               induces symptoms of viral infection

lysogenic       cell reproduces and spreads provirus
