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.
A gene that has been associated with a language disorder in humans and is quite different in apes is the FOXP2 gene.

Answer:
A) Between 1750 and 1760 many improvements were made. Improvements such as spinning and waving the coal on machines were examples of this.
B) Improvements such as said above helped dramatically. They helped by using their power to smelt iron and steel. Because of this, economic life improved.
C) Mining coal helped transform social and economic life. It transformed life because it pumps out deepening mines. Because of this, more and more power transfers to keep the machines running.
