Why do viruses not have special structures or enzymes that allow them to make their own food?
Viruses can use energy in living cells that they infect.
200
Which can modern taxonomy do?
a.) compare the length of RNA among members of a species
b.) distinguish how closely related organisms are
distinguish how closely related organisms are

spirillum
200
A scientist took a boat trip across the Atlantic. On his voyage, he found a lizard, but was unsure of the species. He used his dichotomous key because he wanted to know where the lizard came from, so he could return it to that general area.
Which best describes the purpose of identifying the lizard?
for identifying ecosystems and classifying organisms

guard cells

how can taxonomy help us understand the evolutionary relationships among species?
