Answer:
Broad-spectrum antibiotics can cause antibiotic resistance.
Explanation:
- Antibiotics are the substances that inhibit the growth of or kill the bacteria and hence, these are used as medications for the treatment of a lot of bacterial diseases.
- These antibiotics can either be of broad-spectrum or the narrow spectrum.
- The broad-spectrum antibiotics are the ones that are effective against a variety of bacteria, both gram-positive and negative whereas the narrow-spectrum antibiotics are the ones that target only a specific type of bacteria.
- Since the bacteria can mutate very fast and hence, develop antibiotic resistance, the doctors usually avoid prescribing broad-spectrum antibiotics and only use them when the causal bacteria is completely unknown.
- Hence, in the given case the provider prescribes separate medications for both types of bacteria.
Answer:
Questions, hypotheses, and ideas should be tested against observable evidence.
Explanation:
Skepticism is extremely important, if not fundamental, in all areas of Science. This attitude is based on the belief that all questions, hypotheses, and ideas should be tested against observable evidence. Moreover, it allows scientists to <u>question and think thoroughly about all possibilities behind a phenomenon, instead of just 'believing' any observation or vague and non-supported reason that explains it.</u>
In addition, it allows researchers to investigate all possibilities and test numerous methodologies to be certain and gather enough evidence to explain this certain phenomenon.
Characteristics determined by genes are predisposed by their genetics, whereas characteristics determined by the environment are developed, not predisposed at birth.
