1. Which of the following statements are IMPOSSIBLE? Choose all that apply.

A perfectly functioning hydraulic had a pressure of 38 psi in the fluid near the small piston and a pressure of 38 psi in the fluid near the big piston.

A 25 L container displaced 25 L of orange juice when fully submerged.

A substance underwent condensation during which its temperature remained constant at 45 °C.

A 37 N brick was fully submerged in water. The buoyant force on the brick was 37 N. As a direct result, the brick sank.

Last Tuesday, the Sun heated the Moon via conduction.

The temperature inside a physics laboratory chamber was measured to be 5 °F.

2. Which one of the following statements describes an object moving at a CONSTANT VELOCITY?

A spaceship traveled at a constant speed while making a right turn

The truck accelerated while making a u-turn.

A moped traveled at a constant speed along a straight line path.

A car slowed down while making a left turn.

The motorcycle sped up from 45 mph to 61 mph while moving in a straight line.

Which of the following statements is NOT accurate? Choose all that apply. Inbreeding can change allele frequencies High levels of gene flow between two populations will lead to genetic divergence. Mutation is the process that creates new alleles. Genetic drift usually reduces levels of genetic variation within a population. Genetic drift can sometimes increase the average (=mean) fitness of a population.
