<span>In this item, we are given that a certain biologist in the name of Gregor Mendel demonstrated that the traits are passed on from the parent to the offspring independently of one another. Because other scientists have observed this trait as well, this observation now became a law. Thus, the answer to this question is the first choice. </span>
Answer:
50
Explanation:
egg cells and sperm cells contain half of the chromosomes of a regular cell in an organism, so the number of chromosomes in a heart cell must be double of the chromosomes in a egg cell.

Given question is incomplete. Complete question has been attached.
Answer:
C. Excessive potassium has diffused out causing hyperpolarization.
Explanation:
The nerve action potential can be divided into following stages:
- Stimulus is detected by the cell in resting stage.
- Sodium channels in the membrane open from where influx of sodium ions occur which is called depolarization
- After a while, sodium channels close and potassium channels open from where efflux of potassium ions occur which is called repolarization.
- The membrane potential further lowers due to continous efflux of potassium ions which is called hyperpolarization.
- After a while potassium channels close and membrane returns to its resting stage.
In the given figure, stage 4 depicts hyperpolarization because the membrane potential has dropped to the lowest point below -70mV. Hence, option C is correct.
