Ch 3 lesson 5 and superposition

The creation of a new species can occur through

• microevolution

• symbiosis

• macroevolution

• coevolution

When microevolutions accumulate in a species they can be considered

• deadly

• magical

• a form of symbiosis

• macroevolutions

Which organism (from the notes) shares genetic material with humans?

• mosquitos

• Plants

• Bacteria

• all listed

LUCA means

• Last uncommon ancestor

• Last undiscovered common ancestor

• Last Universal Common Ancestor

• Largest Universal Common Ancestor

Where did your inherited DNA directly come from?

• Your Mom and Dad

• Bacteria

• Common ancestor

• Your Grandparents

What causes species to have variations?

• genes

• gene mutations

• mass extinctions

• symbiosis

What material is the building blocks for cells?

• White blood cells

• Muscle Fibers

• Bacteria

• Proteins

The principle of superposition says

• The oldest rock layers are close to the surface

• The oldest rock layers are deeper in the ground (bottom)

• If a layer crosses another it is younger than the layer it crosses.

• If a rock is included in another rock it is older than that rock

This image shows

• The principle of superposition

• The law of crosscutting

• The law of inclusions

• I like potatoes

The oldest layer is

• 5

• 2

• 6

• 3
