Answer:
<h2>
Hershey and Chase conducted a series of experiments in order to prove that DNA is the genetic material.</h2>
Explanation:
In this experiment, sulphur-35 and phosphorous-32 were used to radioactively label protein and DNA respectively. The bacteriophage (viruses that infects the bacteria) were allowed to infect the <em>E. coli </em>and it was found that bacterial pellets contains P-32 in their DNA and not S-35. This indicates suphur is not found in DNA, it is present in protein. This experiments proves that DNA is the genetic material and not protein.
So, the correct option is A.
The answer is; D. The movement of water molecules from an area of high concentration to an area of low concentration
A is not correct because Osmosis does not create DNA.
B is incorrect because the movement of molecules through the cell membrane is called Passive Transport.
C is incorrect because the division process of the cell's cytoplasm is called Mitosis.
<u>Thus brings us to </u><u>D </u><u>which is the correct answer because Osmosis is the spontaneous net movement of water across a semipermeable membrane from a region of low solute concentration to a more concentrated solution, up a concentration gradient.</u>
When acid precipitation occurs, it effects Earth in a few ways. One way is that when the acid rain soaks into the soil, it removes the nutrients that plants rely on. This, in turn, damages a lot of vegetation. Another way is that it raises acidity levels in water. The higher the acid levels, the more it harms the organisms living in water.
I think this sounds alright
