Some of these can easily be eliminated by knowing that both nitrogen 14 and nitrogen 15 are isotopes ( same element, with the same amount of protons, but with different numbers of neutrons) of nitrogen. So if the only difference between nitrogen 14, 15 , and regular nitrogen is the amount of neutrons...how many protons and electrons should both nitrogen 14 and 15 have? After thinking, you should be able to eliminate A, B,and C.
Mercury is a barren planet with little atmosphere. In many regards it is similar to our own moon. However, it is also very close to the Sun, so humans will have to set up bases in craters or near the Poles to avoid being blinded.

Cool topic you're learning about. Antibiotic resistance occurs because of the fact that bacteria change in response to the use of medicaments, such as penicillin. The problem about antibiotic resistance, an international health crisis, is that people OVERDOSE in medicaments. Antibiotics are known to kill weak and sensitive bacteria, but some resistant bacteria grow and multiplicate, since they know how the medicament works.
Therefore, I would say that bacteria that are not initially killed by the antibiotic, they go to reproduce passing the resistance on to offspring. Antibiotic resistance is a big example when it comes to natural selection.
