Two different cells good day
Answer:
1. Casting
2. Open reduction and internal fixation
3. Open reduction and external fixation
Explanation:
Casting is the process of making use of plaster-of- Paris to cure a fracture.
Open reduction, and internal fixation can be described as a situation whereby surgery is used to repair the fracture-frequently, and involves the use of metal rods, screws or plates to repair the bone. These things remain in place, under the skin, after the surgery. This procedure is adopted when the complicated fractures are not able to be realigned (reduced) by casting.
Open reduction, and external fixation is known to involve surgery to repair the fracture, and placement of a external fixation device on the limb with the fracture. This device is an external frame which supports the bone and hold it in the correct position while it is healing.
Statement D. Is not true.
Trisomy=3 chromosomes; 1 more than the required pair (2)
21=the type of chromosome
So, here we can eliminate A and B.
Now we have C and D.
I know that when sperm cell(s) simultaneously fertilize [an] egg, a class of identical twins will form. Therefore, we can eliminate D, leaving us with merely C. Henceforth, C is your final answer.
