<span>Valence is defined as number of electrons that are present in the outermost orbital. Oxygen is in the 16th column of the periodic table and the total number of valance electrons is determined by units place digit of the column position which is 6 for oxygen. The outermost orbital is the high energy level and there are two in that orbit. So the valance is +2.</span>
Enzymes are made of strings of amino acids chemically bonded to one another. These bonds give each enzyme a unique structure, which determines its function. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids. Amino acids are joined together by peptides, which are broken by proteases.
Answer:
The star could also be said to be 360 Million Million miles from the earth's sun.
Explanation:
A light year equals 9.4607 × 
km.
This is also approximately 6 Million Million Miles.
If we expressed the answer in miles, then we have to multiply 6 by 60.
This is equals to 360.
Therefore, 60 Light years is approximately 360 Million Million miles.

Answer:
We get the materials to make new cells through...
biosynthesis, which puts small organic molecules together to create larger molecules.
Explanation:
Biosynthesis is the process in your body that turns simple structures into more complex structures. It can happen within a single cell (or within a single organelle within a cell), or across multiple cells. In this case, multiple, since it is referring to humans.
Either this option or A.
