Yes like the other person said leeches are most likely
Answer:
c.Both the mass of the objects and the distance between them
Explanation:
The Law of Universal Gravitation states that the force of gravitational pull between objects is directly proportional to the product of the mass of both objects and indirectly proportional to the square of the distance between them.
This means that as the product of the masses increases, the force increases. On the other hand, as the distance between the objects increases, the force decreases.
It can be computed with the formula:

Where:
F = Gravitational force
M₁ = Mass of object 1
M₂ = Mass of object 2
r = distance between the center of the masses
G = gravitational constant (this is a fixed number so the pull is not dependent on this)
1. 0 because they are nonpolar, more concentration of molecules because of a proceess called simple diffusion,
2. o because it is a form of passive energy, low concentration,
3. molecules moving, equilibrium, higher, lower
These processes are all Passive and therefore none require energy although some are different the first is the molecules that can just pass through and yea, then thefacilitated diffusion is through moleules moving because of concentration differences, then Osmosis is when molecules because of water differences.
