 Which statement regarding resistance is false? | d. Many humans have become resistant to antimalarial drugs. |
| If one were to apply the most recent technique used to fight late potato blight to the fight against the malarial infection of humans, then one would | e. insert genes from a Plasmodium-resistant strain of mosquito into Anopheles mosquitoes. |
| Which of the following is correctly described as a primary producer? | d. diatom |
| A certain unicellular eukaryote has a siliceous (glasslike) shell and autotrophic nutrition. To which group does it belong? | b. diatom |
| Diatoms are members of the phytoplankton. Diatoms lack any organelles that might have the "9+2 pattern." They obtain their nutrition from functional chloroplasts, and each diatom is encased within two porous, glasslike valves. Which question would be most important for one interested in the day-to-day survival of individual diatoms? | c. How do diatoms keep from sinking into poorly lit waters? |
| The largest seaweeds belong to which group? | e. golden algae |
| A large seaweed that floats freely on the surface of deep bodies of water would be expected to lack which of the following? | d. holdfasts |
| The following are all characteristic of the water molds (Oomycota) except | e. a feeding plasmodium. |
| Theoretically, which two of the following present the richest potential sources of silica? | c. 2 and 3 |
| Thread-like pseudopods that can perform phagocytosis are generally characteristic of which group? | a. cercozoans |
| Which of the following produce the dense glassy ooze of the deep-ocean floor? | d. ciliates |
| A snail-like, coiled, porous shell of calcium carbonate is characteristic of which group? | e. ciliates |
| What provides the best rationale for not classifying the slime molds as fungi? Their | a. SSU-rRNA sequences. |
| Which dichotomous pair of alternatives is highlighted by the life cycle of the cellular slime molds? | c. unicellular versus multicellular |
| What makes certain red algae appear red? | b. They possess pigments that reflect and transmit red light. |
| The structure and biochemistry of chloroplasts in red algae are most like the structure and biochemistry of chloroplasts in which of the following organisms? | d. green algae |
| A biologist discovers an alga that is marine, multicellular, and lives at a depth reached only by blue light. This alga probably belongs to which group? | a. red algae |
| Members of the green algae often differ from members of the plant kingdom in that some green algae | b. are unicellular. |
| Which taxonomic group containing eukaryotic organisms is thought to be directly ancestral to the plant kingdom? | e. green algae |
| Which of the following are actual mutualistic partnerships that involve a protist and a host organism? | e. A, B, and D |
