They have chemical receptors that combine with specific molecules that allow the membrane to receive signals and respond in a specific way, for example, inhibiting or stimulating internal activities such as the initiation of cell division, Haiti B2B List the production of more glycogen, cell movement, release of calcium from internal reserves. 6- what is diffusion? Diffusion is an irreversible physical process, in which material particles are introduced into a medium that was initially absent, increasing the entropy of the joint system formed by the diffused particles or solute and the medium where they are diffused or solvent. Suppose I throw a drop of ink into a glass of water. The drop remains floating and as time passes it begins to spread throughout the glass. The ink begins to spread throughout the glass.
Both plant and animal cells have cell membranes
This phenomenon is precisely called DIFFUSION. . That is the approximate age of the fossils, although Hall believes that their predecessor must have lived much earlier, “possibly at the same time as the dinosaurs, 65 million years ago. 4- difference between passive transport and active transport The difference is that PASSIVE TRANSPORT does not imply an energy expenditure for the cell. It is always carried out in favor of a gradient, that is, from higher to lower concentration of solutes. Instead, ACTIVE TRANSPORTATION requires energy that comes from the ATP molecule. 5- What is the function of the cell membrane? The cell membrane fulfills several functions: a) it delimits and protects cells;
Animal cells can perform a type of reproduction called sexual reproduction
b) it is a selectively permeable barrier, since it prevents the free exchange of materials from one side to another, but at the same time provides the means to communicate one space with another; c) it allows the passage or transport of solutes from one side of the cell to the other, Phone Lead since it regulates the exchange of substances between the interior and the exterior of the cell following a concentration gradient; d) they have chemical receptors that combine with specific molecules that allow the membrane to receive signals and respond in a specific way, for example, inhibiting or stimulating internal activities such as the initiation of cell division, the production of more glycogen, cell movement, release of calcium from internal reserves.
