Answer:
D) The fungicide will reduce the stability of the ecosystem because nutrients in the soil will be less likely to be recycled, directly impacting plant nutrition and growth.
Explanation:
Fungicide are primarily applied to an area to kill off fungi species in that place.
Fungi are very important groups of organisms. They are natural "recyclers".
In a food chain or web they can be classified as decomposers.
Decomposers are organisms that takes feeds on dead and decaying organic matter.
The produce useful materials and releases nutrients from life back into nature.
Killing them off by applying fungicides is a damaging act to their sustenance.
Without decomposers such as fungi, the ecosystem becomes less stable and soil nutrients will not be properly recycled.
A. an explanation based on prior scientific knowledge or observations

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.

Hope it help!
This is extremely vague, but assuming this is regarding concentration gradient in the nervous system, the Sodium-Potassium pump is responsible for transporting sodium and potassium.
