Answer: Every enzyme has a specific name that can give us insight into the specific reaction that that enzyme can catalyze. We divide them into six different categories.
1) Oxidoreductase - includes two different types of reactions by transferring electrons from either molecule A to B or vice versa. It is involved in oxidizing electrons away from a molecule.
2) Hydrolase - uses water to divide a molecule into two other molecules.
3) Transferase - you move some functional group X from molecule B to molecule A
4) Ligase - catalyzes reactions between two molecules, A and B, that are combining to form a complex between the two. (example: DNA replication)
5) Lyase - divides a molecule into two other molecules without using water and without reducing or oxidation
Sabendo que A Densidade do Metal De Chumbo e 11,3/cm3 means Knowing that the density of lead Metal and 11,3/cm3.
Answer:
leave little space between the molecules.
Explanation:
Matter is made up of small particles called molecules. These molecules present in matter are arranged inside its bulk.
In liquids and solids, the molecules are arranged very close together in such a way that there is only a little space between them. This is why liquids and solids are referred to as "condensed phases".
They are quite unlike gases where there is a lot of space between gas molecules.
No mutations that neither benefit nor harm the organism has no effect on the organism's survival.
Explanation:
The neutral mutations do not cause any effect on the organism they occur. They are called silent point mutations because they do not code for the amino acid change in the proteins.
They have no effect on the organism's survival neither beneficial nor harmful effect.
The neutral mutations do not affect the process of Natural selection.
Answer:
a) 113g Sr3(PO4)2
b) 1.5g H2
Explanation:
The number of moles of Sr used in the equation
= mass/ molar mass
=65.30/87
= 0.751mol
Since the mole ratio of Sr: Sr3(PO4)2 is 3:1
moles of Sr3(PO4)3 = 1/3*0.751
= 0.25mol
grams of Sr3(PO4)3 is = moles * molar mass
= 0.25 * 452
= 113g
b). Since mole ratio of Sr:H2 is 3:3
moles of H2 = 0.751 * 3/3 ---> 0.751 mol
grams of H2 is = moles * molar mass
= 0.751 * 2
= 1.502g
