Explain why facilitated diffusion may need to occur and in what direction the particles diffuse in. Identify the molecules that help in this process.

Why does facilitated diffusion happen:

~ It regulates what goes in and what goes out of the cell

~The cell membrane is permeable to only a select few types of molecules and the molecules that are allowed to move across the cell membrane must be non-polar molecules which are small in size

What direction the particles diffuse in:

~From one side of the membrane where the substrate concentration is high to the other side of the membrane where the concentration is lower

~Diffuses across membranes down the concentration gradient

The molecules that help in this process:

~carbohydrates, amino acids, nucleosides, and ions

Hope this helped you- have a good day bro cya)

succession returns a disturbed

ecosystem to a more stable state. this is also classified into two (2) types:

primary succession and secondary succession. the primary succession arises when

a new land is transformed and a bare rock has been exposed providing an environment

that can be occupied for the first time. while, secondary succession occurs

when a previously occupied environment was disturbed that kills much of all its

community

explanation:

her next move would be to use agarose gel electrophoresis to separate the dna molecules of varying length and create a dna fingerprint.
