I think it is the second answer, sorry if it is wrong/didn’t help.
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.
Intraspecific competition involves an interaction where by members of the same species compete for limited supply of resources. The end result is the reduction in fitness for both individuals. Animals can reduce the intensity of intraspecific competition by exploiting different type of food resources and also moving to other areas that are sparsely populated and with high amounts of food.
A photoautotroph get its energy and carbon from the sunlight and from organic material. Photoautotrophs are organisms that carry out photosynthesis. They use energy from sunlight to carry out cellular processes. Hope this answers the question.
