<span>This is an example of facilitated diffusion using a channel. Diffusion is the process of an object moving across a concentration gradient, usually from areas of higher to lower concentration in membranes. In this case, the diffusion is "facilitated" by the aquaporin molecules and water is allowed to enter or exit the membrane based on concentration level.</span>
Lipids differ from other large biological molecules in that they are not truly polymers ; Lipids are not all made of the same type of monomer. Their association as a group is related to their behavior rather than their structure.

Answer:
UV radiation basically damages skin by transferring energy to molecules in your skin, such as DNA, fat, proteins, etc. These molecules, which are already in their proper arrangement, absorb this energy. If the molecules absorb enough energy, the bonds holding them together can break, forming a new shape completely. For a cell that already has been chugging along smoothly thanks to specific molecules with specific shapes doing specific jobs, this is a big deal and causes serious problems.
Explanation:
UV radiation damage to DNA is a particular problem. DNA is a huge molecule and actually quite fragile. When a molecule of DNA is present in a cell, it resembles a zipper: it has two strands, with each strand tightly bound to corresponding molecules on the opposite side, called bases.
