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:
Explanation:
The respiratory system which includes the organs used for breathing and the skeletal system which is responsible for body support and aids it proper movement interact and can be interwoven functionally in the following ways:
1. The bones in the nose called nasal conchae form swirl like shapes in the nose region that aids the passage of warm air from the nose to the lungs.
2. The centre of the human bones consist of the bone marrow which is responsible for the production and formation of red blood cells, white blood cells and platelets. These red blood cells carry oxygen from the lungs to other parts of the body like a transport system.
3. The thoracic or rib cage protects the lungs from damage and ensures stability.
