The cell theory has three main components. which three scientists’ conclusions formed these components?

hooke, schwann, and virchow
hooke, leeuwenhoek, and schleiden
leeuwenhoek, schleiden, and schwann
schleiden, schwann, and virchow

So the answer is D, because the cell theory has three main components That was Schleiden, Schwann, and Virchow

Schleiden, Schwann, and Virchow

Explanation:

It is important to note that the cell was discovered by Robert Hooke, however he did not participate directly in the cell theory, including, he was not even able to perceive that the cell had several components, but his discovery about the cells was of immense importance.

After Hooke's discovery, many scientists began researching the cells to better understand them. At that time Mathias Schleiden and Theodor Schwann established the cell theory that is used today in cell studies. They were the ones who claimed that all living things must be made up of cells.

After a while, the cell theory was updated, this time by Rudolph Virchow, who discovered that a cell is formed by another cell, through cell division.

Based on this, we can say that cell theory was made based on the studies of Schleiden, Schwann, and Virchow.

the correct answer is: b. pantala flavescens, because these organisms would have a high level of genetic variation due to sexual reproduction.  

because involves two organisms (parents) whose genetic material combines, sexual reproduction leads to genetic variation in new generations of offspring. the offspring is an unique organism, with new genome, more protected with the higher ability to adapted. this process is fundamental to evolution.
