Answer: The correct answer is-
B. by mutating their DNA in response to environmental conditions to gain beneficial traits.
Antibiotic resistance in bacteria means the bacteria is not susceptible to the antibiotic that is the effectiveness of antibiotic against the bacteria is eliminated or reduced.
It occurs when bacteria undergoes mutation that is alteration in the genetic material ( for instance, in one mechanism of resistance, mutation changes the protein that was earlier target for the antibiotic).
Therefore, by mutating the DNA in response to environmental condition ( such as exposure to antibiotic in this condition), bacteria gains beneficial characters and become resistant.
Thus, option B) is the right answer.
Answer:
The deep sea environment is more stable and is less impacted by detrimental events and phenomena such as changes in temperature changes and intense storms.
Explanation:
In 2018, researchers analyzed over 200 species inhabiting in both deep sea and near the sea surface across the world and found that <u>deep sea organisms are more likely to have longer lifespans.</u>
According to their results, the environmental conditions that characterize the deep sea is more stable, enabling deep-dwelling organisms to have longer lifespans. Moreover, deep sea organisms are more protected from events and phenomena that affect shallow-water species, such as changes in temperature and intense storms.
Answer:
The Easter Island once used to be extremely diverse in biodiversity. It had abundant amount of plant and animal species living there.
Biodiversity in the past was extremely high due to favorable conditions there. The temperature and climate of Island was favorable for the growth of plants and animals.
It has mild climate with fertile soil which favored growth but now the scenario is different as it is now barren land with lots of sand and no diversity among plants and animal species is found there.
The roots of plants are able to self-regulate the amount of water they take in. Therefore, by adding this amount of water, Stela is insuring that the plant will have as much water as it needs to grow.
I would say the priority of the nursing intervention would be to find out what these pills are ie the name and compostion and effects of them to ensure they will not harm the patient or have not already harmed him or her and thus remove the concern over the type of pill. Chances are that it would be something innocuous like aspirin or tylenol but that would have to be determined for sure.
