Use the data table below to answer the question.

• Planets located closest to the Sun have less mass.

• Planets have more mass the greater their distance from the Sun.

• Planets less than two astronomical units (AU) from the Sun are less massive than Earth.

• Planets more than two astronomical units (AU) from the Sun are less massive than Earth

Earth takes a complete day to rotate once on its axis. Approximately what portion of one Earth rotation does an hour represent?

A student wants to determine the maximum amount of a solute that will dissolve in 100 mL of a solvent. Based on the data, the student concludes that 30 mg of the solute is the maximum amount that can be dissolved. Which change would best improve the design of this experiment?

• crushing the solute into smaller pieces

• stirring the solvent when adding the solute

• using the same amount of solvent in each trial

• testing solutes with different chemical formulas

Use the maps below to answer the question. Each map shows the same airport locations but different proposed flight paths. Which statement best explains why map 2 is a more efficient flight-path system?

• Map 2 has less frequent flights to reduce the total flight times.

• Map 2 has more frequent flights to reduce the number of passengers.

• Map 2 has a hub-and-spoke pattern to reduce the total number of flights.

• Map 2 has a repeated-triangle pattern to reduce the number of passengers.

In 1883, a volcano erupted on the island of Krakatoa. Most of the plants on the islands near Krakatoa were destroyed. Which inference is most reasonable related to the animals that survived the eruption?

• The animals swam to other islands.

• Fossil evidence of the animals decreased.

• Competition between the animals increased.

• The animals that were herbivores became carnivores.

• The age of the tree and which years it grew the most.

• The age if the tree and what animals lived in the tree.

Use the data table below to answer the question. Property Measurements of Three Elements | Element | Mass (g) | Volume (cm³) | Density (g/cm³) | |---------|----------|--------------|----------------| | copper | 5.0 | 0.56 | 8.93 | | copper | 10.0 | 1.12 | 8.93 | | zinc | 15.0 | 2.10 | 7.14 | | zinc | 20.0 | 2.80 | 7.14 | | lead | 25.0 | 2.20 | 11.36 | | lead | 30.0 | 2.64 | 11.36 | Which conclusion is supported by the data in the table?

• By increasing the mass of an element, its density will increase.

• By increasing the mass of an element, its volume will increase.

• By increasing the volume of an element, its mass will decrease.

• By increasing the volume of an element, its density will decrease。
