MicroBiology HW help I am new to it

Postby MicroBradster » Fri Sep 16, 2011 1:08 am

Hi got a few questions in my assignment that I can't figure out.

Question 1
-There is evidence to suggest that individuals with Crohn experience an improvement in their condition due to a reduction in the inflammation in the bowels. This is an example of a __________ relationship.

A. Mutalistic

B. Commensal

C. Parasitic

D. Opportunistic

E. Pathogenic

What I answered on my paper is B, but I still am not sure about my answer. Can someone correct if I'm wrong. Symbiotes really confuses me.

Question 2 Which of viruses

1. They are unicellular
2. They are acellular
3. They always contain DNA and RNA
4. They can replicate independently of host cells
5. They are considered to be prokaryotic organisms

Answer choices
A. 1,2,3 and 5
B. 1,4 and 5
C. 2,3 and 5
D. 2 and 3
E. 2 only

I answered D, because I know that viruses acellular, they contain DNA and RNA. But I do think they can replicate independently of host cells. However, I am not sure. Please correct me if I'm wrong.

1) I would say E, but I¨m not sure

2) no. 1) they do not contain DNA AND RNA.2) where did you get, that they can replicate independently?
