Answer:  A) Germination

Explanation:

Germination corresponds to the transformation of the seed embryo into a new plant at the cost of the food reserves normally contained in the cotyledon. Some Factors Affecting Seed Germination: 1) humidity; 2) temperature; 3) Aeration; 4) light; 5) Chemical Factors 6) Biotic Factors.

When the seed germinates, it appears that it begins to consume oxygen and release carbon dioxide. This fact reveals that respiration processes began to occur cellular reactions, ie chemical reactions that allow the mobilization of energy contained in the seed reserve substances, with embryo growth and development.

black coffee has a pH of 5, therefore its H+ concentration is ______ times greater than a solution with a pH of 10.
Tju [1.3M]

Answer:

100,000

Explanation:

pH of coffee = 5

pH of solution = 10

Concentration of H+ ions between successive pH values are in multiples of 10

Hence, the pH difference :

pH of solution - pH of coffee

(10 - 5) = 5

Hence, difference in H+ ions will be :

10^5 = 10*10*10*10*10 = 100,000 times
