A. minerals --> high mineral salt (salinity) is too much for many organisms
Cell divison occurs at the end of an eaukaryotic cell's cycle.
1. The first step is mitosis,, a multi-phase process in which the nucleus of the cell divides. During mitosis, the nuclear membrane breaks down and later reforms. The chromosomes are also sorted and separated to ensure that each daughter cell receives a diploid number of chromosomes. In humans, that number of chromosomes is 46 (23 pairs). Because the DNA has replicated prior to mitosis that unique where that result from mitosis are genetically identical.
2. The second major step is cytokinesis. As in prokaryotic cells, the cytoplasm must divide. Cytokinesis is the division of the cytoplasm in eukaryotic cells, resulting in two genetically identical daughter cells.
So at the end of the eukaryotic cell cyclke yoou will be left with two daughter cells that are genetically identical to each other and to their parent cell. Hope you found this helpful ;)
B is the correct answer Crossing over does not occur between genes
Answer:
some things you touch may not seem to have the bacteria you wouldn't expect.
Explanation:
Defibrillation is a method of emergency medicine that can stop ventricular fibrillation or pulseless ventricular tachycardia. An electricity is used to reset the electrical state of the heart so that heart beat will have rhythm controlled by its pacemaker. This is not used in asystole and pulseless electrical activity. Defibrillator is used to give an electric shock to the heart. This depolarizes the muscles in the heart which stops the dysrhythmia, the SA node can eventually produce its own electrical impulse which establish the normal sinus rhythm of the heart. Cardioversion can also be done to provide normal rhythm in poorly perfusing cardiac dysrthymias.
Defibrillators can be implanted, external, transvenous depending on the type of devide used or needed in the current situation.
