Students are investigating the characteristics of different plants. They record the characteristics in a table.
Which plant would best compete for sunlight in a rain forest environment?
Which statement best describes why Texas experiences more hurricanes in August than in January?
Students use a topographic map to study the effects of erosion. The topographic map is shown.
What statement correctly explains where more eroded soil will collect?
Which diagram correctly models the sun, Earth, and the moon during the third quarter of the lunar cycle?
Which of these statements about the mass of subatomic particles is true?
Which question is most relevant to an ecosystem beginning primary succession?
Students push a cart along a smooth floor and collect data to produce the graph shown.
The students use this data to determine and graph the velocity of the cart.
Which graph accurately represents the velocity of the cart?
Gregor Mendel studied the genetics of pea plants. He found that some pea plants produce smooth, round seeds, while other pea plants produce rough, wrinkled seeds.
Which cellular feature determines whether a pea plant produces smooth or wrinkled seeds?
Which is the correct characteristics of stars in each area of the Hertzsprung-Russell diagram?

Two students make models of two elements and label them Element X and Element Y.
Part A
Which statement is true of the two elements’ reactivity?
Part B
Which statement serves as evidence to support the answer to Part A?
(Element X is more chemically reactive than Element Y.)
A table that describes four separate geologic locations is shown.
Which location is near a transform plate boundary?

Which table correctly identifies the charges of subatomic particles?
Certain species of yeast can reproduce sexually or asexually. Which answer choice best compares the offspring from sexual reproduction to the offspring from asexual reproduction?
Students examined the properties of five different elements and recorded observations about their properties in the table. Based on the students’ observations, classify each sample as a metal, nonmetal, or metalloid.
Part A
