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:
The correct answer would be - observational approach.
Explanation:
Observation approach is the research technique that involves the observation of the subject or participates behavior in their natural habitat or state. This will be one of best approach to study.
Similarly when characterizing new findings various aspect of experimental, Observational details or modelling approaches will help in identification , classification and nomenclature. However, in comparison to experimental and modeling approach is more appropriate method for the rare endangered species.
Thus, the correct answer would be - observational approach.
Neurons, also known as nerve cells, send and receive signals from your brain. While neurons have a lot in common with other types of cells, they’re structurally and functionally unique.
Correct matches of terms and its descriptions:
1. Cloning (most controversial method of genetic engineering)
2. hybridization ( breeding organisms because of beneficial traits)
3. recombinant ( DNA DNA from different biological sources that have been combined and culture)
4. selective breeding ( breeding two different species to make a new individual)
Selective breeding is also called artificial selection. Hybridization.is mating organisms of different species to create a hybrid. Cloning produces similar copy of genetically identical individuals.
