MgCl2 dissolves in water because the individual ions in the solid (Mg2+ and Cl-) coordinate with the partial charges in the water molecules. The magnesium cations coordinate with the partially negatively charged oxygen atoms and the chlorine anions coordinate with the partially positively charged hydrogen atoms.
The interphase prepares the cell to divide by enlarging the cell so that when it does divide, there will be space for the nucleus (if it applies to the cell) and the organelles. It will allow the cell to be able to function and later divide on its own. It replicates DNA so that the two future daughter cells will have an even number of chromosomes to remain the cell type that it's parent was.
Hope this helped!

Explanation:
when an organism decays, burning fossil fuels, respiration/breathing.
These are the top three that come to my head, hope this works :)
Answer: Armored fish
Explanation:
The earliest known fossil vertebrates were heavily armored fish discovered fish in rocks from the Ordovician period.
The fossils shows the path from the early aquatic life to the vertebrates, vertebrates to mammals.
The fossils shows that it is vertebrate and are the oldest known fossil ever known. The fossils of the animals and plants helps to known the behavior of the past time and based on that research and study is done.
Answer: Option B) NADH and FADH2
Explanation:
The purpose of the Krebs cycle is to convert potential chemical energy into metabolic energy in the form of ATP that can be used by the body.
Hence, the products of the Krebs cycle include:
- 3 molecules of NADH,
- 1 molecule of FADH2,
- 1 molecule of GTP,
- 2 molecules of CO2
Thus, NADH and FADH2 are two of the products of Krebs cycle.
