C. aid in the transfer of minerals to fungi.
D. are found only on aquatic fungi.

A virulent virus is one that
A. has only DNA.
B. has only RNA.
C. reproduces only with a lysogenic cycle.
D. reproduces only with a lytic cycle

please help ten points mb

Question 1 - A

A. I'm positive it's that. B is just wrong. C is just wrong. LOL D makes me laugh.



Question 2 - A

I believe it's A - not as sure as number one though. I can tell you it's not B, or D. I'm debating between A and C, but I'm like 90% sure it's A.



Question 3 - D

virulent viruses are those that...let me see if i remember..hmm right. it's D, I believe. lysogenic cycle is where the virus waits around a bit in the cell's DNA. Lytic cycle is oddly enough, where the virus lyses the host cell pretty rapidly after entering it.

A A? D?

Where are these questions from? They are a bit ambigouse:

Mycorrhizae form a mutalistic relationship between plant and fungus. they are part of the fungus but the plant exchanges nutirents to the fungi an vice verse.. So im goin for A

Virulence reffers to how deadly a virus is. lysogenic viruses can become virulent. like HIV. this virus is lysogenic and stays in a latent phase the becomes virulent and cause AIDS. Im goin for D becuse the lytic cycle cause cells to die and release toxins whcih is very bad for the organism and so i would say that they are more virulent.

A Lichen = A
Mycorrhizae = A
A virulent virus is one that = D
