A) They all have similar chemical properties.
B: during the early stages of meiosis, chromosomes in a homologous pair exchange segments, the process is called Crossing over.
Each cell that are divided will have complete genetic information itself. So both of them will survive.
Option A.
<h3><u>Explanation:</u></h3>
The sperm and the ovum fuse to form a zygote. This zygote then undergoes cleavage divisions to divide into many cells called morula. Now in the two celled stage, if the cells divide away from each other, it gives rise to monozygotic twins or identical twins.
Both the cell contains nucleus and chromosomes or DNA inside the nucleus. So both of them contains genetic information. Thus both of them survives and develops into two identical twins. This may develop into same amniotic sac or different amniotic sac.
Answer:
answer is D the answer is D the answer is D
The correct order is -
Vessel spasm; plug formation; coagulation
A vascular spasm or vessel spasm is a sudden tightening of a blood vessel. The platelet plug or also called hemostatic plug formation is an accumulation of platelets formed in response to blood vessel wall injury. And coagulation or clotting is the process in which blood changes from a liquid to a gel thus forming a blood clot.
