Answer:
The evolutionary process at work is best described by option <em>B. gene flow</em>
Explanation:
<em>Gene flow </em>also known as migration is any movement of individuals, and/or the genetic material they carry, from one population to another. If gene versions are carried to a population where those gene versions previously did not exist, gene flow can be a very important source of genetic variation. In this case, the nearby population <em>migrates </em>to the mole population. The diagram is a good description of the <em>Gene flow </em>process.
Answer: Option (A) is the correct answer.
Explanation:
The name of 
ion is hydroxide.
Name of 
ion is phosphite.
Name of 
ion is phosphate.
Name of 
ion is ammonia.
Name of 
ion is acetate.
Name of 
ion is oxalate.
Thus, we can conclude that the symbols and names for the ions given correctly is OH-:hydroxide
The volume of chlorine required is 7.71 L.
The reaction between phosphorus and chlorine is:
2P + 5Cl₂→ 5PCl₅
Therefore, 2 moles of P requires 5 moles of chlorine to react with it.
Given mass of P =3.39 g
Molar mass of P=30.97 g/mol
No. of moles of P = given mass/ molar mass = 3.39 / 30.97 = 0.109 moles
2 moles of P requires 5 moles of chlorine
0.109 moles of P will require 0.109 x 5/2 = 0.2725 moles of chlorine
According to ideal gas equation
PV=nRT
2.04 x V = 0.2725 x 0.0821 x 703
V = 0.2725 x 0.0821 x 703 / 2.04
V = 7.71L

Answer: Yes, if there are more shells the nuclear charge decreases.
If temperature were to double the pressure would likewise double. Increased temperature would increase the energy of the molecules and the number of collisions would also increase causing the increase in pressure.
