When twins are formed by the fertilization of two different egg cells and two sperm cells, the twins are referd to as dyzigotic twins
Dizygotic twins are characterized by each individual having unique genetical information, the opposite of monozygotic twins which have an identical genetical information.

Answer:
1.)Rigor mortis, the stiffening of a body several hours after death, arises from a combination of two of the oldest definitions of death – cessation of the heartbeat and cessation of breathing. Once either of these essential functions stops, the cells of the body lose their oxygen supply and can no longer perform aerobic respiration.
Immediately after death, the muscles of the body contract in the same manner as they do when the person is alive. Muscle is formed of bundles of long and narrow cells that can span the entire muscle’s length.
In the resting state, these cells build up the electric potential across their membrane by actively pumping out calcium ions. Upon receiving a signal from a neuron, the muscle cells open the calcium channels in their cell membrane, and the calcium ions rush in due to the voltage difference between the inside and outside of the cell.
2.) I think VFib (ventricular fibrillation) is more serious due to the fact that AFib is not normally life threatening and not nearly as much as VFib and the ventricles pour out all to blood to the body making it extremely vital
When an organism's tiny building blocks undergo a process of splitting into two parts, that's cell division. Another name for cell division is "mitosis."
If you study biology, you'll learn about cell division, when a cell divides into two smaller "daughter cells." During cell division, all the tiny elements of the cell also divide — including the cell's chromosomes, nucleus, and mitochondria. The new cells are genetically identical to the original cell. In addition to mitosis, the simple division of one cell into two, there's also meiosis, when a cell splits into four new cells, each with half the original number of chromosomes.
