Answer:

Light colored peppered moths decreases in number and dark colored peppered moths increases.

Explanation:

The population of light colored peppered moths decreases whereas the dark colored peppered moths increases in number because the light colored peppered moths are visible to the predator birds whereas the dark colored peppered moths are not visible due to dark coating of the trees so they are saved from the birds and therefore, increase in population of dark colored peppered moths occurs and decrease occur in light colored peppered moths population.

Mendel used over 28,000 pea plants in his experiment. How does this large sample size make his results more reliable?

Hitman42 [59]

That would be B.

When u have a larger population at hand the chances of your predictions being right are higher. So for example if he predicted a 3:1 ratio(yellow to green peas) he’d have a higher chance of seeing this ratio in a larger population than he would in a smaller one.

hershey and chase confirmed that dna, not protein, was the genetic material. how do the results of their two experiments support

Gwar [14]

Hi,

Harshey and Chase did a great experimentation which was basically a two step experiment to prove that DNA and not proteins are the actual carriers of genetic information from parents to offspring.

In the first part of their experiment, they used bacteriophages (virus that eat bacteria). They used radioactively labeled sulphur(35S) medium to grow bacteriophages and observed that all the bacteriophages had proteins with radioactive sulphur(35S).

In the next step they allowed these phages to infect bacteria and to their surprise, they found that the bacteria did not had radioactively labeled sulphur in them because the coat of bacteriophage stays outside the body of bacteria when it attacks it. This proved that DNA not proteins were the hereditary material.

To make their results more reliable, they did a second experimentation in which, they marked the DNA of the phage with radioactive phosphorus 32P. After labeling DNA, they repeated the same experiment and this time, they found radioactive phosphorus inside the bacteria.

<em>This meant that the bacteria had DNA of phage entered inside them and this again proved that DNA not proteins are the hereditary material. You can see attached image for better understanding. </em>

Hope it help!
