What term best describes the following organism: a multicellular eukaryote with a chitinous cell wall that is an absorptive heterotroph? a) Fungi. b)…Why are red algae red? What distinguishes plasmodial and cellular slime molds? What are the ecological roles of protists? Why are photosynthetic protists so important to marine/aquatic ecosystems? What limits the growth of these organisms and what causes blooms? What will be affected if marine producers are disrupted?Protists are a group of eukaryotic organisms that are brought together by scientists mostly by convenience. I) What is the relationship between all protists that ties them together? ii) provide an example of a autotrophic and heterotrophic protists group, iii) what is the relationship between the multicellular eukaryotes and the protists?
- In the early 1930s, G. 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. (b) Clam shrimp, a natural predator to P. caudatum, is introduced to the culture containing both P. caudatum and P. aurelia after 24 days. Predict the impact that the clam shrimp will have on the culture and the populations. Justify your prediction.Is protist dna in a nucleus unicellular or multicellular?According to the phylogeny presented in this chapter which protists are in the same eukaryotic supergroup as plants a) green algae b) dinoflagellates c) red algaed both a and c in a lifecycle with alternation of generations multicellular haploid forms alternate with a unicellular haploid forms b unicellular diploid formsc multicellular haploid forms d) multicellular diploid formsa salt water protist is placed in fresh water. Which of the following events would most likely occur? a.) the cell would shrink b.) the cell would remain the same (no change in shape) c.) the cell would start to cry d.) the cell would swell e.) an increase in the action of its cilia

Group of answer choices Some protists are mixotrophic Certain protists share a common ancestor with land plants Some protists are photosynthetic prokaryotes which are similar to the ancestral chloroplast Protists are a polyphyletic group of organisms that often bear little resemblance to each other Although most protists are unicellular, some protists are multicellular as wellYou have discovered a new species aquatic protist that is a primary producer. It cannot swim on its own. It appears to be resistant to physical damage from wave action due to the presence of a glass-like wall. Which of the following organisms would this organism be most like? A) diatom B) dinoflagellate C) apicomplexan D) red alga

What term best describes the following organism: a multicellular eukaryote with a chitinous cell wall that is an absorptive heterotroph? a) Fungi. b) Metazoa. c) Plantae. d) Excavata.Protists are(a) single-celled eukaryotes.(b) multicellular eukaryotes.(c) single-celled prokaryotes.(d) single-celled akaryote. Please try to break the solutions into as many steps as practically possible and the steps should come one by one and they should be short and crisp and plagiarism-free.Which of these is an example of inductive reasoning? A) Hundreds of individuals of a species have been observed and all are photosynthetic; therefore, the species is photosynthetic. B) These organisms live in sunny regions. Therefore, they are using photosynthesis. C) If protists are all single-celled, then they are incapable of aggregating. D) If two species are members of the same genus, they are more alike than each of them could be to a different genus.
