1. Which classification of organisms in life is considered the most allencompassing?

a. Kingdom b. Domain c. Phylum d. Class

Answer: b. The broadest classification of life involves the domain, of which there are three. The system goes from domain to kingdom to phylum to subphylum to class to order to family to genus to species.

2. Which classification of organisms in life is the most specific, resulting in the smallest number of organisms included in the classification?

a. Class b. Family c. Subphylum d. Genus

Answer: d. Genus is the most specific of those listed, although species is the most specific of the classification systems.

3. Which kingdom includes archaea species?

a. Eubacteria b. Archaebacteria c. Protista d. Plantae

Answer: b. There is just one kingdom in the archaea species, which is the archaebacteria kingdom, making up a diverse group of extreme organisms, called so because of the often-extreme environments they live in.

4. Which organism is considered prokaryotic rather than eukaryotic?

a. Blue-green algae b. Diatoms c. Amoeba d. Green algae

Answer: a. Blue-green algae are actually cyanobacteria rather than algae so these are prokaryotes. The others are Protista, which are eukaryotic cells.

5. What do the archaea cells have as part of their cell walls that make them unique in their own domain?

a. Pseudopeptidoglycan b. Peptidoglycan c. Cellulose d. Chitin

Answer: a. Pseudopeptidoglycan is the main component of the cell wall of archaea, which makes it unique to these organisms.

6. What aspect of archaea cell membranes is not unique to their membrane?

a. They have a lipid monolayer b. They have a mirror-imaged glycerol molecule c. They have an ester linkage d. They have multiple, branched side-chains

Answer: c. Each of these is a unique feature of the lipid membrane of archaea except that they have an ether linkage in their cell membrane, which adds to their stability in high temperatures and in high salt environments.

7. What type of classification is the Protista classification?

a. Phylum b. Domain c. Kingdom d. Family

Answer: c. The Protista classification is a kingdom and is one of the six different kingdoms that life exists as.

8. What is used as the major difference between the types of Protista?

a. Means of locomotion b. Cell membrane types c. Metabolic features d. Cell wall types

Answer: a. These organisms are differentiated by their different means of locomotion.

9. What is the shell made of in the radiolarians as a whole?

a. Calcium carbonate b. Chitin c. Cellulose d. Silicates

Answer: d. The radiolarians secrete a silicate shell, which is unique to these species. The foraminifera will secrete chitin or calcium carbonate shells or tests.

10. What organism type is responsible for African sleeping sickness and Chagas disease?

a. Trypanosoma b. Amoeba c. Paramecium d. Flagellates

Answer: a. The genus Trypanosoma is responsible for the tropical diseases known as African sleeping sickness and Chagas disease.
