Without its atmosphere, Earth would be
bombarded by meteorites, similar to mars, relatively lifeless. Without the atmosphere objects can just enter the atmosphere and cause serious harm to us, but with the atmosphere it basically reduces damage and shrinks it to size. Without the atmosphere earth would be like mars since it doesn't have a atmosphere. Without the atmosphere earth would be relatively lifeless since without air, us humans cant breathe so we will not survive.
Explanation:
Bella is right
Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. In humans, genes vary in size from a few hundred DNA bases to more than 2 million bases.
Answer: Shaun must consume 6 more g of protein to reach the required amount.
Explanation:
Given : Recommended amount of protein = 200 calories
Now 4 calories = 1 gram of protein
Thus 200 calories = 
g of protein.
Calories consumed per day by Shaun = 176 calories
176 calories = 
g of protein.
Thus Shaun need to consume = (50-44) g = 6 of protein to reach the required amount.
Shaun must consume 6 more g of protein to reach the required amount.
The chemical reaction involving Mg(OH)2 and HCl is:
<span>Mg(OH)2 + 2HCl
--> MgCl2 + 2H2O</span>
So we see that for every 2 moles of HCl, 1 mole of Mg is
reacted.
Calculating for moles HCl:
moles HCl = 0.300 M * 0.215 L
moles HCl = 0.0645 mol
The moles Mg then is:
moles Mg = 0.0645 mol * (1 / 2)
<span>moles Mg = 0.03225 mol</span>
