protozoans
animal-like protists
fungus (fungi)
eukaryotes that have cell walls, heterotrophs that feed by absorbing their food, and use spores to reproduce
HOW DO VIRUSES INTERACT WITH THE LIVING WORLD?
Though viruses can cause disease, they can also be used to treat and prevent illnesses.
host
vaccine
flagellum
long, whiplike structure that helps a cell move
spores
tiny cells that can grow into a new organism

algae

what is the smallest of the four topics
viruses
cellular respiration

contractile vacuole
a structure that collects and expels excess water from the cell
hyphae
branching, threadlike tubes that make up the bodies of multicellular fungi
WHAT ARE THE CHARACTERISTICS OF FUNGI?
fungi are eukaryotes that have cell walls, heterotrophs that feed by absorbing their food, and use spores to reproduce
Can a vaccine help chronic diseases
no
