Answer:
The human cell cycle has two main phases: the interphase and the M phase
Explanation:
Just like every cell, the human cell cycle has two main phases which are;
- The interphase
- The M phase
The interphase phase is further divided into 4 respective sub-phases namely;
phase which is essentially a resting/quiescence phase. It reserved for cells that have no need to divide unless they are called upon.
phase, a phase where cell growth and development takes place.- S phase, a phase where DNA is synthesized.
phase, a phase where protein is synthesized.
The M phase is known as the active division phase. M can be mitosis or meiosis depending on the type of cells. Reproductive/sex cells will undergo meiosis while somatic/vegetative cells will undergo mitosis.
Mitosis is further divided into prophase, metaphase, anaphase and telophase while meiosis is divided into prophase I, metaphase I, anaphase I, telophase I and prophase II, metaphase II, anaphase II, telophase II respectively.

The answer is B.
Veins are blood vessels that carry the blood towards the heart. The Vessels that carry the blood way from the heart is called artery
Here we would be using Hardy Weinberg equation for the calculation of allele and genotypic frequencies.
Dwarf genotype frequency = 
= 25% = 0.25
Frequency of allele t = q = 
= 
= 0.5
According to the equation,
p + q = 1
p = 1 - 0.5 = 0.5
Now, the frequency of heterozygous tall plants would be-
2pq = 2 * 0.5 * 0.5 = 0.5 or <u>50% heterozygous tall plants</u>.
I did research but I couldn't find the exact answer but those are some websites maybe they could help you. I am sorry I did my best to help.
