the phenomenon of the unequal separation in the meiosis is called as nondisjunction. If the nondisjunction causes the missing chromosome in a haploid gamete, the diploid zygote it forms with the another gamete will then contain only one of the copy of that chromosome from the other parent, this condition is known as monosomy.
The term "monosomy" is used to describe the absence of one of the member of the pair of chromosomes. Therefore, there are about 45 chromosomes in each cell of the body instead of that usual of 46.
Turner syndrome is the only and full monosomy that is seen in the humans — all other cases of the full monosomy are the lethal and the individual will not about survive development.

Answer:
tall
Explanation:
The genotype Tt is heterozygous, which means it has both the dominant and recessive trait in the genotype. The reason it is tall is because that is the dominant trait, and the dominant trait basically covers up the recessive trait (unless you are talking about incomplete dominance or codominance).

The two events that occur when gravity causes a nebula to collapse into itself are:
A. Nuclear fusion start.
B. A new star forms.
Explanation:
- Nebula are giant clouds of dust and gases.
- These clouds are considered as progenitors of stars and planets.
- The gravitational pull within these giant clouds result these large masses to collapse towards their centre.
- The gravitational collapse results in tremendous rise in temperature till a point where nuclear fusion begin .
- The stars are born out of such mechanism and act as a source of heat and light in universe.
Answer: It will slow down.
Explanation: This is because the same amount of blood that usually goes through will have to fit through a blocked vessel. Only a little will be able to go through at one time, causing the blood flow on the other side to slow.
(That is really dangerous. The build-up will eventually burst the vessel) Just an FYI
