Communicable diseases can be spread from person to person(the flu, cold) but non-communicable diseases are diseases that can travel from person to person(like diabetes).
Answer:
A postulate that is part of the cell theory is cells come from cells (option 2).
Explanation:
The third postulate of the cell theory is "All cells originate from other cells".
After Schleiden and Scwann proposed the first postulates of the cell theory, in 1863 the anatomist Rudolf Virchow observed how <u>cells were able to reproduce themselves and give rise to new cells</u>, in the context of his studies on cancer. The third postulate of the theory is due to this scientist, who was able to conclude that every living cell originates from another cell.
The three postulates of the cell theory are:
- <em>Cell is the basic structural and functional unit of life.
</em>
- <em>All living beings are made up of one or more cells.
</em>
- <u><em>All cells originate from other cells.</em></u>
Based on this contribution from three scientists, the foundations of cell biology were laid.
The other options are not correct because:
- <u><em>Cells como from bacteria, non-living matter or non-cells</em></u><em> are part of theories about the origin of cells.</em>
