<span>Explanation: Oxygen is the more electro-negative of the atoms in the water molecule, so it tends to pull the 'shared' electron more to itself. Thus, the oxygen atom has a greater time-share of all electrons, and therefore the hydrogen atoms are more positive for a partial lack of electrons</span>

Answer:
3. An Apple Turning Brown
Explanation:
When an apple is cut (or bruised), oxygen is introduced into the injured plant tissue. When oxygen is present in cells, polyphenol oxidase (PPO) enzymes in the chloroplasts rapidly oxidize phenolic compounds naturally present in the apple tissues to o-quinones, colorless precursors to brown-colored secondary products.
The given statement is False
The agriculture has impact on the the level of the organic content in soil because it is taken up by the plants. For example if a particular plants needs carbon in abundant amount for their growth. Then maximum part of the carbon is taken by the plants and there is a difference in the quality of soil which means there will be a deficiency of carbon in the soil for the next round of same plant. Just because of this reason there is a need of crop rotation. Crop rotation enables the soil to maintain the proper amount of organic matter in the soil.
