<span>Red tides are formed by dinofllagelata, eucaryotic flagellate organisms. Dinoflagellates are marine plankton which means they drift on the surface of the sea. Those are small, nonmobile organisms who sometimes bloom in concentrations of more than a million cells per ml. The bloom is often red colour so the phenomenon is called red tides. </span>Under such circumstances, they can produce toxins, dinotoxins<span> which are capable of killing fish, so that's why this occurrence is dangerous.</span>
That would be the chloroplasts. They are small cells in a leaf that store chlorophyll.
With the graph attached below you can determine when was the moment that
<span>Sally tripped and fell.
You can also see that they run for 4 minutes before starting to rest. Then, after resting 10 minutes (starting at the 9 min mark and ending at 14) they started running a bit, that's why the line is not at zero anymore. After moving a bit, between 15 and 16 min mark, they stop distancing for one minute. So the answer is: Sally fell at the 15 min mark.
