Answer:
Which is faster, visual or auditory reaction times?
Answer:
Diffusion is the process in which molecules and ions move from a region of high concentration to low concentration. Its also how cells transport waste out of the cell and nutrients into it hence being very crucial. Diffusion also occurs without the expenditure of extra energy using a procedure known as passive transport. (Osmosis is a form of diffusion but deals with water exclusively).
Examples of where diffusion is important;
In the intestines - Digested food molecules such as amino acids and glucose move down the concentration gradient from the intestine into the bloodstream. Wastes such as carbon dioxide or urea travel via diffusion from the body's cells to the bloodstream.
Osmosis plays a major role in living organisms. It aids in the transportation of nutrients from cells to cells and also helps to remove the waste's metabolic products from the cell. The purification of blood in the kidneys is also dependent on the process of osmosis.
Answer:
White fur is only an evolutionary advantage if the creature can hide in snow.
If you live in a temperate forest biome and want to hide from enemies, you wouldn't want fur that sticks out brightly against the dark forest.
Just like, if you lived in a snowy biome, you wouldn't want black fur that would stick out against all the snow.
So no, white fur is not an evolutionary advantage in a temperate forest biome
Hope this helps!

A planarian can regrow any missing body part. Truth be told, in the event that you take a planarian and excise it into a few little pieces, every last one of those body sections can recover into an entirely different worm.
