I can answer the third one:
Photosynthesis takes place in two stages<span>: light-dependent reactions and the Calvin cycle (light-independent reactions).</span>
Lets see both procedures:
<span>Mitosis is a process of cell duplication during which one cell gives rise to two genetically identical daughter cells.
Meiosis, on the other hand, is a division of a germ cell involving two fissions of the nucleus and giving rise to four gametes, or sex cells, each possessing half the number of chromosomes of the original cell.
Mitosis is used by single celled organisms to reproduce; it is also used for the organic growth of tissues, fibers, and mibranes. Meiosis is useful for sexual reproduction of organisms. I hope this can help greatly</span>
This injury is fatal because, The phrenic nerve regulates breathing and operates the diaphragm.
<u>Explanation:</u>
The motor ability is provided by the Nerve called Phrenic nerve to the diaphragm. This is a muscle that is very important for the respiration to take place in human. When a damage or injury occurs to the Phrenic nerve, it may result in the paralysis of diaphragm.
When this is damages there may be difficulties in breathing and only small amount of air can be inhaled. Thus the paralysis of this nerve results in the prevention of the victim to find difficulties in respiration. Thus, the example given is fatal because, the phrenic nerve regulates breathing and operates the diaphragm.
