|---|---|
| What are viral capsids | The capsid is made from virally encoded proteins that are assembled in the host cell |
| What is density dependent transmission | are viruses or bacteria that can be spread without exchanging large amounts of body fluid (e.g. the common cold, influenza) |
| what is frequency dependent transmission | spreading these infections requires behaviors where individuals physically exchange bodily fluids or come into contact with contaminated body fluids (e.g. blood or semen) |
| what are virus envelopes made of | viral proteins and components from the host cell’s plasma membrane |
| how do viruses obtain the envelope | when they emerge or bud through the plasma membrane of the host cell. |
| what is the virus envelope used for | avoiding the immune system of the host as well as for attaching to new host cells to begin the replication/infection cycle |
| what are viruses that infect bacteria | phages |
| what helps euglena locomotion | the flagella and pellicle |
| what are diatom shells (or modes) made of | silica |
| what organism causes red tides | Blooms of dinoflagellates in the oceans |
| what do amoebas use to feed and move | pseudopedia |
| what is cilia on the outside of the paramecium used for | locomotion and to sweep prey items |
| what is mycelia made up of | hyphae |
| what type of fungi has motile zoospores | chytrids |
| what is the name of the structure that releases basidiospores | basidium |
