Punnett Squares

Typically on a Punnet Square, we write the male genes on the top and female genes on the side.

Bring the top letters down and side letters over.

Each box is worth 25% or 1/4.

Open Ended

Seafloor spreading is the result of magma and plate tectonic movement. The plate boundary is considered to be a divergent boundary as the crust moves away from each other. What type of rock is associated with sea floor spreading? Explain why.

Multiple Choice

Increase in temperature causes the particles to

• slow down

• move faster

• stay apart from each other

Multiple Choice

Why does a higher temperature increase the rate of a reaction?

• It increases both the frequency collision and energy of reactant particles

• It only increases the frequency of collision

• It only increases the energy of reactant particles

• It reduces the activation energy of the reaction
