<span>Base on the data in the graph, the event that would most likely happen if the paramecium were placed in distilled water is that "The contractions would increase." This is the result of a hypertonic solution. </span>The net movement of water in an aqueous solution is form the higher
water concentration to a lower water concentration. A
hypertonic solution has higher solute in the cell than the outside. The
movement is from the cell to the outside and so the cell will shrink.
Answer:
The correct statement concerning the cell membrane lipid molecules is that "energy is not expended during diffusion" (Option d)
Explanation:
Biological membranes are formed by two lipidic layers arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, and their hydrophobic tails against each other. Membranes are fluid, which means that molecules that form it have the capability to move through it.
Lipids can easily change places with other neighbor lipids by <u>lateral diffusion</u> in the same layer. This is passive diffusion, which means that it does not need energy to happen.
Lipids can also diffuse transversally to the other layer, but this kind of movement is not as easy as lateral diffusion.
There are also other lipidic movements as rotational diffusion that imply the rotation of the molecule.
Through this lipidic bilayer, there is also a passive transport of some particles from one side of the cell to the other which happens because of concentration differences.
