What can you conclude from this cladogram?

• The dog is more closely related to the monkey than the fish

• The monkey is an ancestor to the fish

• The snake is more closely related to the monkey than the dog

Answer explanation

If they are closer together on the cladogram they are closer related!

Some goats look like an extinct animal from millions of years ago. This suggests the extinct animal-

• evolved from a goat

• remained the same species over time

• shares a common ancestor as the goat

Kingdoms Plantae and Fungi are both:

• Heterotrophic

• Prokaryotic

• Multicellular

Answer explanation

Plants make their own food and are autotrophic, and both ae eukaryotic.

If an organism is autotrophic, they-

• Cannot make their own food

• Have a cell wall

• Make their food themselves

• rely on other organisms for everything

Which of the following is a unicellular, prokaryotic organism?

• Fungi

• Archaebacteria

• Protista

Answer explanation

Archaebacteria are prokaryotic and only have one cell.

What kingdom is multicellular, eukaryotic, and unicellular?

• Virus

• Eubacteria

• Protista

• Plantae

Organisms are classified based on their-

• Bone functions

• Bone structure

A grasshopper and a cricket are in the same order. Because of this, we can assume they are in the same-

• Phylum

• Family

• Species

• Genus

Answer explanation

They will be in everything above, but not everything below. Remember KPCOFGS!

Which of the following could be in the kingdom Plantae?

• Eukaryotic, multicellular, heterotrophic

• Eukaryotic, multicellular, autotrophic

• Prokaryotic, unicellular, autotrophic

Answer explanation

Which of the following is the largest and most broad?

• Order
