Coin flipping simulates the events of mitosis and the production of sperm or eggs
a_sh-v [17]
Coin flipping simulates the events of mitosis and the production of sperm. This is because females carry XX chromosomes so all eggs will have a singular X chromosome. It is the sperm that determines the sex of the foetus: males have XY chromosomes and therefore sperm will carry either X or Y chromosomes (a 50/50 chance, just like flipping a coin)

Plasma is about ________ percent of the composition of blood and carries cellular elements and other substance
svetoff [14.1K]

Answer is 55%.

Blood is fluid connective tissue that consists of two main components, plasma and formed element. Blood plasma is a clear extracellular fluid, which is a mixture of proteins, enzymes, nutrients, wastes, hormones and gases. Formed elements are made up of the blood cells (red blood cells and white blood cells) and platelets. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells.

The formed elements can be separated from plasma by centrifuge. On separation of blood components, it is evident that formed elements make up 45% of total blood volume while the plasma makes up 55% of the total volume.
