Explanation:
.-. all late
Answer:
Vitamin C is a very good antioxidant, as it interferes with redox reactions, reducing or inhibiting oxidation.
Oxidation is a reaction that occurs with the presence of oxygen. For oxidation to occur, there must also be an oxidizing agent and an electron-releasing agent.
Vitamin C delays this donation of electrons from the apple to the oxidizing agent that is oxygen
Explanation:
In addition, vitamin C has other very good properties, but both in apple and in the human body the antioxidant function is present, that is why it is often used in fruit salads so that the apple does not turn dark
Answer:
(i) Available in the plant:
Chlorophyll
(ii) Available in the soil:
Water
(iii) Available in the air:
Carbon dioxide
(iv) Available during day:
Light / Light energy
Explanation:
For photosynthesis, your raw materials are chlorophyll (to absorb light energy from the sun), light, carbon dioxide, and water. The products are glucose and oxygen.
Chlorophyll can be found in the leaves of a plant.
Light is from the sun.
Carbon dioxide is taken in from surrounding air.
Water is taken in by the roots, along with mineral salts, before being distributed to other parts of the plant.
During the night, respiration takes place. You can think of it as opposite of photosynthesis. Materials are glucose and oxygen, and products are carbon dioxide and water.
