Wow that's a good one :). Think about it like this. When you put antibiotics in place where bacterias live, probably most of them will die, however there might be "some" who are resistent to the antibiotic by their nature, (mutations etc.) so among the bacterias which were exposed the antibiotics those resistent ones will survive. And bacterias have a system for exchanging DNA to make each other more resistant, its called "conjugation" look it up. By conjugation they give each other genes which will help them survive. So if we summarize, those who are already resistant survive (which is a cause of natural selection in an environment of antibiotics) and help others resistant too.

Answer:
Semi-permeable membrane
Explanation:
In semi-permeable membranes, only some substances can pass through. Sometimes, some can also pass through the channel protein molecules or transport proteins on the cell membrane.
Answer:
Cellular respiration
Explanation:
Cellular respiration is the process through which organic compounds are broken down enzymatically to release energy in form of ATP in the cell. Cellular respiration occurs in the mitochondria and cytoplasm.
Mitochondria contain enzymes that catalyze and control reactions of respiration. The inner membrane is folded into cristae to create large surface area for attachment of enzymes. The end products of cellular respiration are carbon dioxide, water and energy.
<em>Denaturation involves the breaking of many of the weak linkages, or bonds (e.g., hydrogen bonds), within a protein molecule that are responsible for the highly ordered structure of the protein in its natural (native) state. Denatured proteins have a looser, more random structure; most are insoluble.</em>
