<span>Scientists found that the cytoplasm of cells undergoing mitosis, if injected into cells at other stages of the cell cycle, could induce the non-dividing cells to start mitosis. This suggested that a chemical signal was present in the cytoplasm of dividing cells that was responsible for "telling" the cells that they should proceed into mitosis. By fractionating the cytoplasm into its components, scientists were able to isolate the signal that triggers mitosis.</span>
<span>This is because benthic zone are too
dark to support photosynthesis. Due to their depths, sunlight is unable to penetrate
the above lying waters and reach the region. This way plants cannot carry out
photosynthesis hence cannot grow. This is why only </span>decomposers,
detritus feeders can be found in the benthic zone.
For Question 36, the answer is Customary. Customary means commonly practiced, used, or observed. Since Cellphones have become one of the most commonly used objects, for communication, it is customary.

Answer:
c. 3, 5, 1, 4, 2
Explanation:
1. (3) food substance dissolves in saliva
2. (5) food substance enters taste pore and attaches to receptor on gustatory hair
3. (1) gustatory cell depolarizes
4. (4) neurotransmitter released by gustatory cell
5. (2) action potential stimulated in gustatory neurons
<em>Saliva has digestive functions that help food to be easily swallowed. We need saliva to taste foods because it dissolves the chemicals. The sense of taste is called gustation. We taste something with our tongue and then sensations would be carried via the facial (VII) cranial nerve. One of the newest taste to be described is umami. </em>
