Explanation:
Isotopes:
₁₅³¹P and ₁₅³²P
Given parameters:
₁₅³¹P ₁₅³²P
Mass number = 31 32
Atomic number = 15 15
The two atoms are isotopes. Now let us derive numbers of their subatomic particles
₁₅³¹P ₁₅³²P
Protons 15 15
Electrons 15 15
Neutrons (31-15) = 16 (32-15) = 17
Because they are isotopes, they differ in the number of neutrons alone.
Isotopy is the existence of two or more atoms of the same element having the same atomic number but different mass numbers due to the differences in the number of their neutrons.
We clearly see that the mass number and number of neutrons pertaining to the atom differs. This makes them isotopes.

Answer;
1000:1
The ratio of the volume of typical eukaryotic :prokaryotic cells is 1000:1
Explanation;
-Eukaryotic cells are generally much larger than prokaryotic ones and this difference in volume has several implications. One advantage is that bigger cells can afford to have more things stored in the cytoplasm such as organelles. This means it is not as costly to a eukaryotic cell to have structures taking up space. In a prokaryote, space is at a premium and anything not being used is pretty rapidly degraded.
-If the diameter of a typical eukaryotic cell is approximately ten times the diameter of a typical prokaryote, then it means the linear scale factor or the ratio of the lengths (diameter) is 10:1.
-The volume scale factor or the ratio of the volumes is got by getting the cube of the ratio of the length (diameter). Thus;
The volume ratio is (10:1)³ = 1000:1
<span>Answer:During expiration, the volume of the thorax decreases as the diaphragm rises/relaxes.
In expiration the air gets out of the lungs and it's not occupying as much space in the lungs, so the volume of the thorax will decrease. Meanwhile, the diaphragm can go to his relaxed stage and move </span><span><span>superiorly</span>
