Answer:
B. monitoring the transverse diffusion of human proteins within a mouse cell membrane
Explanation:
fluid mosaic model of membrane is considered to be as that structure of membrane in which protein layer is embedded between the two layers of lipids.
monitoring the transverse diffusion of human proteins within a mouse cell membrane did not verify the fluid mosaic model of membranes.
When something needs to be transported against its concentration gradient, or a molecule is too big to simply diffuse through a membrane, active transport has to be used. So active transport requires energy (ATP).
Examples:
1. Antiport pumps: transport one substance in one direction while transporting another substance the other way. An example of this is the sodium-potassium pump.
2. Symport pumps - uses a substance that wants to move from an area of high concentration to low concentration and carries another substance against its concentration gradient. An example of this is the sodium-glucose transport protein
3. Endocytosis - large amounts of extra cellular fluid can be taken into a cell - needs ATP to bind proteins in the cell membrane and causes them to change their shape...which eventually causes the surrounding of the fluid to be brought in (a vesicle).
4.exocytosis - opposite of above
Mostly through bites, I think.
<span>Single covalent bonding
Covalent bonding is the type of bonding that takes place when two atoms share a pair of electrons with each other. In order to form a molecule, these two electrons are glued to one or more atoms. One important contribution of non-covalent bonding is the oxygen we breathe. On the other hand, polar covalent bonding happens when a pair of electrons are being shared unequally because one of the atoms spends way too much time with another electrons rather than with the atoms. </span>
