The 5-kingdom classification system has the following kingdoms: Monera, Protista, Fungi, Plantae and Animalia.
Monera is characterized by a group of single-celled prokaryotes. Protista is composed of single-celled eukaryotes and forms a diverse class of organisms. It consists of organisms that have features like those of animals or plants or fungi. The fungi are saprophytic organisms that feed on decaying organic matter. Plants are the photosynthetic multicellular eukaryotes and animals are motile multicellular eukaryotes.
Thus, protists form a distinct evolutionary lineage. They are not a convenient term used for multiple evolutionary lines of eukaryotes that are not plants, animals or fungi. They do not refer specifically to single-celled photosynthesizers or heterotrophs but consist of a diverse group of organisms. Hence the correct option is a.

Chapter 28 -15 pts This micrograph (Chapter review, p. 615) shows a single-celled eukaryote, the ciliate Didinium (left) about to engulf a second ciliate, Paramecium, as its prey. Historically, Didinium and Parameciumn have been classified as protozoa since they are single-celled, heterotrophic eukaryotes. Identify the eukaryotic supergroup to which ciliates belong and describe the role of secondary endosymbiosis in the evolutionary history of this supergroup. Also, as a second part of the question, indicate whether...

1. In biology, the term "ionic bond" is used differently than in chemistry. A biological "ionic bond" is used to describe the interaction of an R group containing a carboxyl group (–COO–) with an R group containing an amino group (–NH3+). From this description, what do you understand a biological "ionic bond" to be? a. van der waals interaction b. hydrogen bond c. Electrostatic interaction d. covalent bond 2. The three dimensional arrangement of alpha helices, beta-sheets and other parts...
