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>
<u>Answer:</u>
The Acquired Immune Deficiency Syndrome (AIDS) was clinically identified as a fatal disease in 198.1 decade.
<u>Explanation: </u>
AIDS which is a pandemic globally, is caused by a communicable virus called Human Immunodeficiency (HIV) Virus. In US, the first five cases were clinically exposed on 5th June, 1981. HIV majorly spreads from one to the other through three routes namely sexual contact, transmission through body fluids or from mother to fetus via pregnancy/ delivery/ breast-feeding. Vaccines that offer partial protection exists but there is no permanent cure for this disease.
I believe it is Fast-twitch muscle fibers. Slow-twitch fibers are used for people who exercise for a long period of time such as running, swimming, and cycling.
