Question

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

Answer 1

B.) a virus

Step-by-step 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.
