Answer:
1. Can bacteria affect any cell? How does it target?
Bacteria are much larger than viruses, and they are too large to be taken up by receptor-mediated endocytosis. Instead, they enter host cells through phagocytosis. Phagocytosis of bacteria is a normal function of macrophages. They patrol the tissues of the body and ingest and destroy unwanted microbes.
2. What causes the damage to your tissues?
When the body sustains damage from trauma, disease or simple wear and tear, it normally results in the formation of a lesion or cartilage gap on your joint surface.

Answer:
The group that receives the treatment in an experiment (here, the watered pot) is called the experimental group, while the group that does not receive the treatment (here, the dry pot) is called the control group. The control group provides a baseline that lets us see if the treatment has an effect.

Explanation:
One of the earlier experiments that confirmed DNA and not proteins as genetic material was conducted by Alfred Hershey and Martha Chase
Hershey and Chase experiment showed the genetic material of virus is DNA not protein. Their experiments demonstrated that Phage are composed of DNA and protein, when phage infect bacteria, their DNA enters the host bacterial cell but not protein before infection
Hershey and Chase experiment prove that DNA is the hereditary material.
From chargaff base pairing rule, the ratio of purine to pyrimidine is a cell is 1:1. Since adenine pair with thymine and cytosine pair with quanine, this means the percentage of adenine will equal the percentage of thymine.
%A = %T and %G = %C.
%A + %T + %G + %C =100
If a DNA contains 8% adenine, therefore the percentage of thymine is 8%
8% + 8% + %G +%C = 100%
16% + %G +%C = 100%
%G +%C = 100%-16%
%G +%C = 84% = 84%/2= 42%
Since %G = %C
Then %G = 42%, %C = 42
I think it would either be c or d...
