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.

The prtists that causes malaria evolved from a photosynthetic ancestor and has the remnant of a chloroplast. The organelle no longer functions in photosynthesis, but it remains essential to the protist. Why might targeting this organelle yield an antimalarial drug that produces minimal side effects in humans?

There are three different kinds of phycobiliprotein molecules used to pass light to chlorophyll: phycoerythrin is responsible for capturing green light, phycocyanin is responsible for capturing orange-red light, and allophycocyanin is responsible for capturing red light.Since light can only penetrate to certain depths in oceans, phycobiliproteins capture the light available and pass it through various pathways of phycobiliproteins until the emitted light is red, which is absorbed by chlorophyll. Use the figure below to answer the following questions. (View image attached) 1. Justify the claim that photosynthetic organisms that live more than 75 feet below the surface of the ocean need phycoerythrin to survive. Provide reasoning that explains this claim.arrow_forward

F. 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.
