Sodium is less dense than water
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:
Bacteria
Explanation:
Biotic factors are living things
The eye-hand coordination or hand-eye coordination refers to the tendency to perform activities, which need the corresponding application of eyes and hands, like an activity that utilizes the information the eye gets to mediate the hands to carry out a motion.
In the given case, as Mark wants to build his upper body strength and hand-eye coordination then he should show some interest in sports, like baseball or softball as the mentioned sport ranks highest in the requirement of most of the hand-eye coordination and upper body strength.
