The presence of phospholipids in the lipid bilayer accounts for the relative impermeability of membranes to water-soluble molecules. Phospholipids are types of lipids that are made up of components that include two fatty acids, a polar molecules, glycerol, and phosphate groups.
of the presence of phospholipids in the lipid bilayer.
The interior of a lipid bilayer is normally highly fluid. In the liquid crystal state, hydrocarbon chains of phospholipids are disordered and in constant motion.
At lower temperature, a membrane containing a single phospholipid type undergoes transition to a crystalline state in which fatty acid tails are fully extended, packing is highly ordered, and van der Waals interactions between adjacent chains are maximal.
Kinks in fatty acid chains, due to cis double bonds, interfere with packing of lipids in the crystalline state, and lower the phase transition temperature.
256.52 g mol-1since sulfur molecules are S8.
Cell membranes act very much like a fluid on a molecular level. The phospholipids move around each other with relative ease, making the membrane flexible. With an increase in temperature, the molecular movement will increase throughout the membrane thus leading to looser fits among molecules and a more permeable membrane.
Part of the cell that functions to maintain homeostasis relative to the cell's passage of large molecules and particles to an area outside the cell.
No. Though all cell membranes have the same general characteristics outlined in any Biology textbook, they are all unique in type of proteins. Cell membranes between members of the same species will differ, and membranes within the same individual with differ also. The location of proteins will differ too, since they are subject to drifting and relocation. Some integral proteins will move slowly or not at all due to their connection to the cytoplasm, but others take advantage of the fluidity of the phospholipid bilayer.
Warmer air is less dense because the molecules have greater relative motion. Warm air rises over cooler, denser air.
The relative formula is like a career of someones jobs they do
if we talk about the relative movement of molecules in solids the movement of molecules is slower than liquids and gases because in solids molecules are bound together with relatively stronger forces
The concentration of water molecules in the air expressed as a fraction of the concentration at which a fog forms.
Rarefractions and compressions both are waves that carry energy with them
Cholesterol helps the membrane keep its shape and relative size. Cholesterol also helps with cell signaling which is how cells communicate with each other.
it can move around more freely(relative to solid). takes shape of whatever it contains.

If you mean 24/30 and 4/5 then they are both equivalent fractions
He published a paper called (translation) "Essay on determination the relative masses of the elementary molecules of bodies and the proportions by which they enter these combinations". It is from his work that we get 'Avogadro's Number' the number of molecules/atoms in a mole.
