nlexa [21]

Answer:

Explanation:

In the Hershey and Chase experiment, they aimed to show where the phage DNA went when it exited the protein coat and entered the bacteria. In this scenario, the two student's approach won't work because amino acids (and therefore all proteins) also have nitrogen atoms which ultimately means that the radioactivity would not distinguish between DNA and proteins and the experiment will not provide the correct results.

Which is allopatric and which is sympatric
Helen [10]

Answer: The correct answer is-

Allopatric-  option 2.

Sympatric - option 1.

Allopatric and sympatric are primarily the two major mechanisms for  speciation ( formation of new species from an ancestral species).

In allopatric speciation, a population splits into two different species when it is isolated by physical or geographical barrier.

On the other hand, sympatric speciation occurs wihtin the same area. A population splits into two species that is becomes reproductively isolated when a change in the chromosome number occurs.

Thus, option first corresponds to sympatric whereas option second shows allopatric speciaton.

Based on the Resource Use and Conservation Virtual Lab, Which tactic can do the most to keep the water debt less than the water
Viefleur [7K]

Answer: D. Replacing thermal power plants.

Explanation:

Thermal Power Stations are some of the biggest users of water in the world because water is integral to producing electricity in them. These stations burn fossil fuels like coal which then vaporizes water so that it becomes steam which then drives turbines that produce electricity.

Water is also used for cooling high temperatures produced.

If these thermal stations are replaced with something that uses less water, it will go a long way in keeping the water debt less than the water supply.
