Answer:
Cro and lambda
Explanation:
In the lysogenic cycle, the viral DNA is within the host DNA, while in the lytic cycle the viral DNA is separated from the bacterial cell, replicating independently from the bacterial DNA. The cro and lambda are DNA-binding repressor proteins of the bacteriophage lambda which bind to different operator sites, i.e., different genetic sequences found between the promoter and the structural gene. These proteins are known to have complementary functions in lytic and lysogenic cycles. The cro protein repressor binds non-co-operatively to operator DNA regions, while the lambda protein contains a domain (carboxy-terminal) that binds co-operatively to operator regions.
The answer to your question is A. Higher latitudes receive less radiation due to the curvature of the Earth.

Hey mate....
Explanation:
This is ur answer.....
<em>In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration.</em>

Answer:
C. The pond experienced an algae bloom.
Explanation:
From the graph we see that the fish population continue to decrease with time. As time passed on, the fish population keeps suffering a decline. In retrospect, the population of the algae continued to increase.
- We can ascribe this to the pond experiencing an algae bloom.
- It could be due to condition called eutrophication.
- When nutrients become very much in water and more algae is produced.
- This leads to dissolve oxygen amount reducing in the water body.
- Therefore, fishes will die off.
