A medical patient is suffering from mysterious fainting spells. A medical team works to get to the bottom of the problem and identify the cause. So the correct option is B.

<h3>What is the scientific method?</h3>

The start of a scientific investigation is observation. This means anything that catches the attention of the scientist. For example, for a  cancer biologist, a certain kind of cancer might be an observation that can't be treated with chemotherapy and he would wonder why it is so.

For all the sciences, the core is a problem-solving approach which is called the scientific method. There are five basic steps in the scientific method. These are:

  • Observation of a phenomenon
  • Questioning the reason or cause for it.
  • Hypothesizing or giving a testable explanation
  • Making a prediction based on the hypothesis.
  • Testing the prediction.
  • Using the results to develop new hypotheses or predictions.

Therefore, the correct option is B.

Tju [1.3M]

Answer:

Unwanted/unplanned growth weeds will cover the whole area.

Explanation:

Because the area was previously forested hillside, it has all the environmental conditions (nutrients, rainfall, etc.) to support the vegetation. Hence, Although the soil layer is thin, natural weathering process would increase the depth of soil layer over the years. Later on, biogeochemical cycles on top layer will result into successful nutrients release to support vegetation. Hence, in a few years, there will be growth of weeds (unplanned vegegation).
