Because the more complex an organism become the more surface area to volume ratio.This means that unlike simple organism(like insects) who rely on diffusion for transport of oxygen and nutrients is readily available due to their excellent surface area to volume ratio. However if an organism has a bad surface area to volume ratio(larger organisms) they require a more efficient flow of oxygen and nutrients throughout their body.
The concentration of hydrogen in a solution increases as the pH of the solution becomes more acidic.
Everything that happens in an organism, including its development, depends upon a complex series of biochemical reactions, and those reactions in turn are controlled by proteins which are synthesized by genes.
what will happen to the organism
Initially invisible infra red radiations. Then as temperature increases it becomes red. As still temperature increases it turns into yellow. When further increase happens, it starts giving out almost all colors including blue, violet and so it seems white hot. As an object is heated, it's maximum electromagnetic frequency increases. So you can measure the heat of an object by its emitted spectrum.
That is hot enough to ignite hydrogen fusion, so the nebula becomes a star (possibly with planets).
population increases
If an organism becomes extinct, the food web collapses. Every organism is needed for it to function properly.
It becomes snow!
It becomes smaller as the detail becomes better.
Its entropy increases.
it becomes sillay
Its pH value becomes decreased.
The field of view becomes smaller when magnification increases.
At greater distances, the force of gravity becomes less.
The orbit becomes more eccentric until the orbit becomes almost a strait line.
Probability becomes more accurate the more trials there are.
When the water gets warmer the water becomes less dense.
