"Human cells that contain one set of 23 chromosomes are called gametes, or sex cells; these eggs and sperm are designated n, or haploid. The matched pairs of chromosomes in a diploid organism are called homologous chromosomes."
The correct answer is that it will not affect the length of the tails of any of the offspring.
The modification in the tail of the mouse was not because of its genes, rather, it was because of the environment. The correct answer is that it will not affect the length of the tails of any of the offspring.
The modification in the tail of the mouse was not because of its genes, rather, it was because of the environment. The passing of the traits from the parents to the offspring is known as heredity, and the offspring attain the genetic information of their parents. Thus, the mouse will pass on only the features present in its genes to its offspring.
Answer:
B is INCORRECT
Explanation:
Action potential in contractile cells can be divided into 3 phases
1. Rapid depolarization; caused by fast influx of sodium ions into the cells. Last a few milliseconds.
2. Plateau phase: This is a sustained positive membrane potential, after rapid depolarization, caused by a balance between calcium ion influx and slow potassium ion efflux.
3. Rapid repolarization: Eventually there's a closure of all other ion channels except the potassium ion channels causing rapid efflux of potassium ions, returning the membrane potential back to negative.
A refractory period usually occurs after undergoing an action potential. During this time no action potential can occur.
This occurs in the first stage of secondary syphilis
