20 is the Number of Neutrons of potassium.
The correct answer is B. Protection and dispersal of seeds
Explanation:
In plants, fruits are structures that form as a result of fertilization, which makes ovules become seeds and flowers maturate to become fruits. This is necessary for the reproduction of plants, as fruits contain seeds or genetical material that is protected by different layers and leads to new plants if seeds are dispersed. The process of dispersal commonly occurs as the fruit falls from the plant or is eaten by other organisms and then disperse in other areas, which allow plants to reproduce. According to this, the main function of fruits is protection and dispersal of seeds.

my answer is A..
These three (3) chemical reactions include Hydrolysis, Carbonation, and Oxidation.
• Hydrolysis is a chemical reaction caused by the water in which water responds with the rock and changes the size and chemical arrangement of the minerals that reduces opposition to weathering.
• Carbonation is an involvement of water with carbon dioxide to create carbonic acid. It appears when the rock minerals respond with fragile carbonic acid made when water associates with carbon dioxide in the air that deeds on the rock by breaching and disbanding the mineral substances.
• Oxidation is recognized as rusting, a procedure whereby the rock minerals misplace one or more ions or atoms in the occurrence of oxygen. Once minerals in the rock rust it will develop less opposition to weathering. The oxygen associates with other constituents via oxidation method given that rise to ion or atom lose.
