Pea plants produce two types of seeds: round seeds or wrinkled seeds. A gardener cross-breeds two pea plants and draws a Punnett square (shown in the figure below) where (R) represents the dominant allele for round seeds and (r) represents the allele for wrinkly seeds. The outside of the square displays the genes of the parents, whereas the inside of the square shows the genes of the potential offspring.

What is the probability that their offspring will have wrinkled

seeds?

The outside of the square displays the genes of the parents, whereas the inside of the square shows the genes of the potential offspring.

Based on the given Punnett square, which of the following is a true statement?

• Both parent plants are homozygous.

• Both parent plants are heterozygous.

• One parent plant is heterozygous, and the other is homozygous.

• Neither parent plant is heterozygous or homozygous.

There were three finalists in a soapbox car race. Contestant 1 built his car out of aluminum, Contestant 2 built his car from steel, and Contestant 3 built his car from wood. Each car was the same size. The contestants all started from rest at the top of a hill that is 20 meters higher than the finish line at the bottom of the hill. If friction and air resistance are ignored, the conservation of energy states that the loss in potential energy equals the gain in kinetic energy (motion energy). In order to calculate each contestant’s potential energy and gained kinetic energy, the mass of each car, the mass of each driver, and the final velocity reached by each contestant were recorded in this table.

Which material is the heaviest?

• wood

• steel

• aluminum

• the materials all weigh the same

The solar system consists of the sun, eight planets and their moons, asteroids, and comets. Because the sun is much bigger than any of the planets (it contains more than 99% of the mass of the solar system!), the planets orbit the sun. The time taken for one complete revolution around the sun determines how long one year is on that planet. In addition to orbiting the sun, the planets also rotate around their own axes. The time a planet takes to complete one rotation about its axis determines the length of one day on the planet. This table shows some detail regarding the movement of the planets in the solar system.

According to the table and the given information, which of the

following is a true statement?

• The planet with the shortest day is Mars, and the planet with the

  longest year is Jupiter.

• The planet with the shortest day is Mercury, and the planet with the longest year is Earth.

• The planet with the shortest day is Jupiter, and the planet with the longest year is Neptune.

• The planet with the shortest day is Earth, and the planet with the

  longest year is Saturn.
