Could someone help me with this bio question? Explain how fungi and protists are both beneficial and deadly to humans?

Bioluminescence can only be functionally important if detected by other organisms. What are two reasons that dinoflagellates may emit bioluminescence?

Carefully observe the cell morphology of the two organisms below. Then, draw the cell morphology. Cells should be drawn large enough so that you can show an accurate shape and arrangement. Your drawing should capture the relative length and width of the cells. There should be no pointy corners, no open circles, no extra “tails” and no overlapping rings. Specify cell morphology and if the organism a) Escherichia coli or b) Staphylococcus aureus

Please hand draw Foraminifera W.M. and label it with the following terms: Phylum Foraminifera, Tests.   Please be sure to include all of the terms provided in the illustration.

Complete Table 1by doubling the number of bacteria (Clostridium sp.) and diatoms (Chaetoceros sp.) every 30 minutes and 60 minutes, respectively, and by writing the log10 of this number in the appropriate columns with the results , Draw a graph showing the growth (N) of the populations of both species from time = 0 (also written as t0) to time = 310 (t310) minutes. Draw both populations on the same graph. NB: It will be necessary to plot Chaetoceros sp. on a second y-axis. Label the axes and provide a suitable legends.

Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves. Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…
