Biology hw

1)  Finish answering the 3 questions that go with the Life video episode, "Creatures of the Deep."

2)  Categorize the following organisms into logical groupings based on similarities and briefly explain what factors were used to create the groups and subgroups:

®                E. coli, single celled animals, sponges, trilobites, snails, slime molds(a fungus), clams, grass, sting ray, ant, fish, salamander, ferns, cyanobacteria,  reptiles, house fly, pine trees, dinosaurs, spider monkey, Amoeba, lion, bumble bee, mammals, Mastodon, Stegosaurus, frogs, Tyrannosaurus  rex, dandelion, horses, and Homo sapiens.

®                 For example:  lemons, limes, and oranges=citrus fruits (all have a thick rind and citric acid); pineapple, banana, and mango= tropical fruits (grow in tropical climates); raspberry, boysenberry, and blackberry=berry fruits (grow on thorny bramble bushes)
·         You may earn from 1-10pts extra credit for categorizing each of the groups of organisms into logical sub groups.  citrus fruits = lemons, limes, and oranges; tart citrus fruits = lemons and limes
