Ecological, temporal, geographical
A) Positive feedback loop
B) Positive feedback loop
C) Negative feeback loop
I believe it'd be A because the virus infects cells whereas the Giardia Lambia only releases toxins.
Answer:
Proten W
Explanation:
SDS-PAGE gel is a method used for the separation of proteins in which proteins are separated based on their length (smaller proteins move faster through the gel, due to less resistance).
When treated with proteolytic enzymes, proteins are cut and become short fragment. This means that the fragments formed after the use of proteolytic enzymes, will move faster and thus, migrate a longer distance. Proteolytic enzymes in Set 2 cells will act only on plasma membrane proteins (because they cannot penetrate), while in Set 2 they will act on both, plasma membrane and interior proteins. Control group will have only the large fragments (not treated with enzyme).
Protein W travels the same distance on a gel of proteins from Set 1 and Set 2, but different than control group. It means that the proteolytic enzyme worked the same on Set 1 and Set 2.
In cell division, the cell that is dividing is called the parent cell. the parent cell divides into two daughter cells. the process than repeats in what is called the cell cycle. cells regulkate their division by communicating with each other hope it helps,if you need help just ask and i will be more than happy to help. :)
