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.

it is also called short-stroke engine. Usually the bore diameter is<span> greater than its stroke length. This gives a bore/stroke ratio greater than 1:1.</span>

Answer: On the Northern horizon
Explanation:
If the star is directly overhead when you stand at the North Pole, it will sink further and further the more you move south towards the equator due to the earth's curve. When you get to the equator, the star will ideally sit right on the northern horizon.
After one crosses the equator however, the star will disappear from view. It is therefore not possible to see this star from anywhere south of the Equator to the South Pole.
