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 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 |
