In 1940, Danielli and Davson proposed that the cell membrane was a bilayer of phospholipids. These phospholipids were sandwiched between two continuous layers of proteins as shown. Later, electron micrographs revealed proteins embedded in the
phospholipid bilayer. Unlike the Danielli-Davson proposal, the proteins were scattered throughout the outer surfaces.

Which of the following best modifies the Danielli-Davson model of the cell membrane?

maritime tropical may be your answer.

endo:

regulates body hormones, aldosterone, vasopressin

neural:

signal, regulates body using electric signals, reflex

endo has to do with hormones; aldosterone and vasopressin are both hormones. i also had this question and got it right : d

the solute can move "downhill," from regions of higher to lower concentration, relying on the specificity of the protein carrier to pass through the membrane. this process is called passive transport or facilitated diffusion, and does not require energy.

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
