alex41 [277]

Large molecules such as hormones materials are expelled from cells during exocytosis

<u>Explanation:</u>

The materials inside the cells are transferred to the outside of the cell and this manner is termed as  Exocytosis. This method is termed as a kind of active transport since it needs energy for this transformation process. One of the major purposes of this process is to discharge trash matters like hormones and proteins.

For a cell to cell transmission and chemical signal messaging these methods are essential. Proteins that are newly generated are transferred to the peak of the plasma membrane by exocytosis. There are three general pathways of exocytosis.

Bess [88]

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.
