Answer: Water inside the seed coat creating a pushing force, breaking the seed coat.

Explanation:

Seed germination can be defined as the process by which a new plant emerge out from a seed. The radicle is the first emerging part from a seed and it develops into a root and the plumule is the second emerging part and it develops into a shoot. The light, water, adequate temperature, and soil are the factors that are necessary for seed germination.

According to a given situation, the popcorn kernel will receive the moisture necessary for the germination process, the water will imbibe into the seed coat creating pressure inside the seed and which will cause the seed coat to break and the new plant parts or seedling will emerge out of the seed coat.

Answer: The given statement is false.

Explanation:

Weight :It is defined as the measure of force exerted upon the object by the gravity. It is measured in Newtons.

W=mg, where W= Weight , m = mass of the object , g = acceleration due to gravity = 9.8m/s^2

Here the given statement is False, the correct statement will be:

Match each of the substances with the expected pH of the resulting solution when they are added to neutral water. Determine if a
Tamiku [17]
To determine the expected pH of the resulting solution of the following substances, create a balanced chemical equation of their ionization in water:

HI

HI + H2O ---> H+ + I-

It completely dissociates into H+ and I-. Due to the presence of the Hydronium Ion, the solution is acidic. 

KBr

KBr + H2O ----> HBr + KOH

The salt KBr is formed by a strong base and a weak acid, therefore, the solution it forms with water is basic. 

LiOH

LiOH + H2O ----> Li+ + OH-

It dissociates completely in water, turns into Li+ and OH-. Due to the presence of Hydroxide Ion, the solution becomes basic.
