“Watermelon snow” in Antarctica is caused by a certain species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high-altitude, year-round snowfields. In both locations, Uv light levels tend to be high. Propose an explanation for why this alga appears reddish-pink.
The question is also in the picture
THIS IS A MULTIPART QUESTION, PLEASE ANSWER ALL QUESTION
Using the image:
5. Identify whether the organism is a green alga, a diatom, a dinoflagellate, Eubacterium, or a Cyanobacterium. Explain the characteristic(s) that led you to that identification.
6. a. What type of microscopy (brightfield, darkfield, or phase contrast) was to obtain the image? Explain how you can tell.
b. Name a different type of microscopy would be also appropriate to use to visualize the organism in the image. How would the image change if you used that type of microscopy instead?
7. The image was taken using a microscope that has 10X, 40X, and 100X objectives. What is a possible magnification for the ocular lens on this microscope? Explain your response or show calculations.

O The alga photosynthesizes produce sugars the fungus is able to use, while the fungus keeps the alga safe from being eaten.
O The fungus serves as the substrate the alga needs to perform mitosis, while the alga produces enzymes the fungus needs for decomposition.
O The fungus produces the sugars the alga uses for cellular respiration, while the alga provides a safe place for the fungus to live.
O The alga offers camouflage to the fungus against herbivory, while the fungus secretes toxic substances that release nutrients from the rocks to the alga.

Gause carried out a series of experiments using two species of ciliated protists (Paramecium), which are single-celled eukaryotic protozoans. The protists were cultured together and separately, with the bacteria being the single food source. The results are shown in the figure below. (a) Based on figure, identify and explain the interaction that is taking place between P. caudatum and P. aurelia.
