Answer:
The movement is caused by the convection currents that roll over in the upper zone of the mantle. This movement in the mantle causes the plates to move slowly across the surface of the Earth.
Explanation:
When an environment is hypotonic, the cell has more solute so solvent move from outside the cell to inside causing the cell to swell.
WHAT IS TONICITY?
- Tonicity is the ability of a solution to induce water loss or water gain in a cell. A solution can either be; hypertonic, hypotonic or isotonic
- A hypertonic solution has more concentration of solute than its surroundings while a hypotonic solution has less concentration of solute compared to it's surroundings.
- If a hypotonic solution has less solute, this means that it will have more solvent (water). Based on the principle of osmosis, water moves from a region of high concentration to region of low concentration.
Hence, water will move into a cell that is located in a hypotonic environment, causing it to swell.

The answer to this question would be true.
Given data:
● Angular velocity of the turntable ω = 33 rev/min
Therefore,
ω = 33 rev/min
ω = 33rev/min × 2π rad/rev × 1 min/60 sec = 3.45 rad/s
● The distance of the watermelon seed from the axis of rotation r = 7.8 cm = 0.078 m
● μs = the coefficient of static friction
Section a:
The seed is undergoes circular motion and it is been effected by centripetal acceleration.
ac = rω^2
ac = 0.078 × 3.45^2
ac = 0.9284 m/s^2
Therefore,
the centripetal acceleration of the seed is 9.274 m/s^2
Section b:
If the seed is observed not to slip at the course of the circular motion, then the supplied frictional force given by the seed and surface of turntable would at least be equivalent to the centripetal force working on the seed.
Centripetal Force = Frictional Force
mrω^2 = μsmg
μs = rω^2 /g
μs = 0.078 × 3.45^2
------------
9.81
μs = 0.09464
Thus,
the coefficient of static friction is 0.09464.
