D = tricyrtis hirta
E = Fraxinus excelsior
b. i. organisms with similar characteristics that can breed with each other to produce
fertile offspring
ii. binomial naming system
7. a. insects
b. p = arachnids
q = arthropods
r = myriapods
b. have 3 different segments, head, thorax abdomen
2 pairs of wings
8. a. 2 and 3. because same genus, so same common ancestor
b. have vascular bundle in stem with ring like shape, have flowering parts with
multiples of 4 and 5
9. a. prokaryote, protoctist
b. no cellulose cell walls, no chloroplasts
c. i. x = rna, y = protein coat
ii. because they do not display all 7 characteristics of living organisms; they show
reproduction but only when they enter a living cell and forcefully make copies of
themselves
