<u>Antibiotics are used to kill bacteria:</u>
Antibiotic is a naturally produced substance that is used to kill bacteria. The first antibiotic was penicillin produced from fungus. The word antibiotic means against life which means it is against the life of pathogenic bacteria.
In the case of the living organism that is treated antibiotic is ‘pro life’. Antimicrobials are used to kill pathogenic microbes like fungus, bacteria, virus etc. Sometimes the microbes become resistant to the antimicrobials and they are said to develop is antimicrobial resistance.
When pathogens develop antimicrobial resistance newer drugs have to be developed in place of the earlier ones to treat the disease.
YES.The distribution of bases in sea urchin DNA and salmon DNA follow Chargaff's rules because the percentage of A bases is approximately equal to the percentage of T bases, and also the percentage of G bases is approximately equals to the percentage of C bases in both species. According to Chargaff's rule the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.

Explanation:
Is there a picture you forgot to post with the question?
In the problem you mention, which I assume comes from the study of finches in the Galapagos, some birds evolved to have different beaks, depending on the food available. Depending on what kind of seeds there are, different beak sizes were selected for, with those with the right fit eventually winning out over the rest on the individual islands.
Answer: its CO2 for the first one
Explanation:
Precipitation differences are the factor that does not contribute to "water stress" on the Earth.
<u>Explanation:</u>
- Less ocean water sources, population differences, Scarcity of economic water resources are the factor which leads to water stress on the Earth.
- Precipitation differences do not cause much difference in water stress. So it will not contribute to the water stress.
- An increase in population will cause major water stress because availability drinking water is less in the earth. Population increase can cause a major problem.
