Answer:
Solutes dissolved in water on either side of the cell membrane will tend to diffuse down their concentration gradients, but because most substances cannot pass freely through the lipid bilayer of the cell membrane, their movement is restricted to protein channels and specialized transport mechanisms in the membrane. Although ions and most polar molecules cannot diffuse across a lipid bilayer, many such molecules (such as glucose) are able to cross cell membranes. ... Channel proteins form open pores through the membrane, allowing the free passage of any molecule of the appropriate size.t is the proteins, therefore, that give each type of membrane in the cell its ... Many extend through the lipid bilayer, with part of their mass on either side ..... Many hydrophobic membrane proteins can be solubilized and then purified in an active, if not entirely ..... Many Membrane Proteins Diffuse in the Plane of the Membrane.
hope this helps :)
Warning Dont copy all of this i just answered this question to give you idea of what it is
Answer:
The first bullet is theory
The second bullet is Law
Explanation:
A scientific law is an explanation of a tested hypothesis and a mathematical method.
I am not totally sure but I believe this is correct
Cellular respiration is the process that cells use to break down food to use as an energy. Aerobic cellular respiration uses oxygen and yields many more ATP molecules than anaerobic cellular respiration, which does not use oxygen and yields only two ATP molecules.
The answer is A, bacteria can move around, use energy, and reproduce just like humans can, the only difference is they're single cell and we're not.
All of the above is the answer
