Answer: Limited Surface area - Volume ratio
Explanation:
Cells in various organisms usually have the same size be it a blue whale or an earthworm, a Human or a mouse or an Elephant and a squirrel. This is down to the way the cell is structure.
The Cell needs to absorb nutrients to survive while getting rid of waste material. For that to happen it needs an adequate surface area. The problem is that as the cell absorbs more nutrients thereby increasing in volume, this rise in volume occurs at a faster rate than the cell can increase its surface area so the surface area will keep shrinking.
Therefore, in order to have enough surface area to keep up the process of absorption and excrement, the cell will stop growing at the certain point and this process is similar in most if not all organisms.
You can start with:

Answer:
C) Gravitational force
Explanation:
Steve is whirling a rubber cork, tied with a string to his finger, over his head as shown in the figure.
The motion of the cork is similar to the motion of a planet in the Solar System around the Sun.
Therefore Gravitational force is similar to the tension in the string. The reason is because the planets revolve around the sun due to the Gravitational force due to which they are pulled towards the sun and do not stray away.
