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.
Answer:
They are the same
Explanation:
A membrane pump is a protein embedded within the cellular membrane which helps the cell transport molecules into and out of the cell. The proteins help the cellular membrane's job of being semi-permeable (allowing certain things in and out). Some molecules cannot travel directly through the cellular membrane (ions, large polar molecules) and have to rely on these proteins to get through the membrane. There are two types, channel and carrier protein pumps. Channel proteins allow for simple passive diffusion where as carrier proteins can allow for active transport as they shape/conform in regards to the molecule they are transporting. Both pumps are specific in what they transport.
Answer:
Other problems of pesticide use include most pesticides kill beneficial species as well as the target pest species, pesticides do not stay put, pesticides harm wildlife, and pesticides can threaten human health. Farmers pay more and more for a pest control program that often becomes less and less effective.
