Answer:
The options are:
a) Crutchfield tongs
b) Buck's
c) Balanced suspension
d) Thomas splint
The correct answer is b) Buck's
Explanation:
Buck's is a type of skin traction that is used when there is a fracture, mostly in the femur, or hip. This type of traction reduces pain and keeps the length of the bone but does not reduce the fracture. The other options mentioned are skeletal tractions.
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.
