Nondisjunction is defined as the failure of the chromosomes to seperate during cell division. An animal with a haploid number of 6 (diploid number of 12) undergoes meiosis, and at the meiosis II (cells are already haploid from the meiosis I), nondisjunction occurs. The mature ovum will contain 6+1 chromosomes (n+1) because there is an extra chromosome from the nondisjunction. The second polar body will contain 5 chromosomes (normal would be 6) because the second polar body did not receive that extra chromosome due to nondisjunction. In the event of fertilization of the abnormal ovum with a normal sperm, the zygote will be a diploid (12 chromosomes) normally but since the ovum as an extra chromosome from the nondisjunction then the zygote will have an extra chromosome (13 chromosomes). One pair of chromosomes has an extra single chromosome and this is called a trisomy.

Answer:
Insulin helps control blood glucose levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.

If you are a smoker quit smoking. Eat three meals a day, doesn't mean you have to eat a lot. Eat alot of vegetables and fruits - at least 1/4 cup worth a day. Avoid processed/canned fruits as they most likely added sugar to it. Exercise daily at least half an hour a day. Stay hygienic. Eat more proteins than junk food. Lessen the amount of snacks a day to 1-2 each should be 100 cals or below. Avoid eating a lot of carbs as it can raise insulin and make you feel hungry often.
