Answer:
Before the antibiotic, the ‘good’ bacteria had colonized her intestines and formed colonies that made up her biome. These colonies out-compete other bacteria, including ‘bad’ bacteria that tried to grow in the intestines hence protecting her intestines from infection.
However, the antibiotics wiped out the established colonies of ‘good’ bacteria –destroying her biome- and gave room for recolonization of the intestines by bacteria. The secondary succession gave a chance for the ‘bad’ bacteria to also thrive and cause her massive infections.
I would say D idk or it would be B I hope this helps
Answer:
Within the steps of the scientific method there will always be 2 things that vary when doing an experiment, which are:
<u>- Formulate a hypothesis
</u>
<u>- Record observations and collect data on your experiment.
</u>
<u></u>
Explanation:
The scientific method is a set of ordered and logical procedures designed to explain some phenomenon, to establish internal or external relationships between the facts and a way to expand our knowledge.
For this, the laws that explain chemical or physical phenomena must be applied that allow us to explain if this knowledge is useful for man.
Within an experiment the most important thing is the question, it is the starting point of an experiment.
But when asking the question the hypotheses will always exist, the question will be the same, if it changes the experiment changes, but the hypotheses will always be within every physical or chemical change of the experiment.
And all the time, with any movement we make, we are collecting information and making observations of everything that happens.
