Answer:
True
Explanation:
The plasma membrane does not allow the charged and polar substances to cross through its inner core that is made up of non-polar fatty acid tails of the phospholipids. Therefore, membrane proteins serve as transport proteins. Some of the transport proteins allow the movement of substances down the concentration gradient without any energy input. This passive movement of substances via membrane transport proteins is called facilitated diffusion.
Carriers and channels are the membrane proteins that facilitate the diffusion of substances. Carrier proteins pick the substances from one side of the membrane and undergo a change in shape to deliver the substance on the other side. Channel proteins make a passage for the movement of substances. Examples: aquaporins, ion channels.
A deep current is colder because it normally doesn’t get as much sunlight as a surface current
I believe the correct answer is theory
Stem cells are known to be the type of cell that goes through the determination process. This process involves the cell to undergo a very stable change where it's perfectly accurate to really happen. Stem cells are known to be fully capable of that once it activates.
