The structures are analogous; the organisms do not have a common ancestor.

The structures are homologous; the organisms do not have a common ancestor.

Students are studying fossilized animals from the bottom of an ancient lake. The students make drawings of the fossilized animals. One student claims that the fossilized animals are related to living animals. Which statement best supports the student’s claim?

The fossilized animals have body shapes and parts that are similar to the body shapes and parts of living animals.

The fossilized animals have body sizes that are similar to the body sizes of living animals.

The fossilized animals are made of rocky materials that are similar to those in the bones of living animals.

The fossilized animals show signs of having once lived in habitats that are similar to the habitats of living animals.

Planaria are flatworms that reproduce asexually. Catfish reproduce sexually. Which statement best compares planaria and catfish?

Planaria require less time to produce offspring, and catfish require more time to produce offspring.

Planaria have offspring that are genetically different, and catfish have offspring that are identical.

Planaria produce offspring one at a time, and catfish produce large numbers of offspring at one time.

D. Planaria require large amounts of energy to produce offspring and catfish require little energy to produce offspring.

The Cretaceous-Tertiary (K-Pg) event occurred about 65.5 million years ago. The causes are not completely known, but over fifty percent of all plants and animals went extinct. Evidence shows that Earth experienced a massive heat event that triggered fires, volcanic eruptions, and earthquakes. These activities released large amounts of debris into the air. The debris blocked the sunlight and caused Earth’s surface temperature to become much cooler.Which type of organisms would have most likely survived this event?

Organisms that were able to hide and to store energy to keep warm survived over time.

Organisms that were able to eat only plants on land survived over time.

Organisms that were able to grow very large on land survived over time

Organisms that were able to use sunlight to heat their bodies survived over time.

Arctic hares are adapted to live in cold environments such as the Arctic. Scientific studies indicate that human activities contribute to a rise in the average global air temperature, resulting in a decrease in Arctic snow cover. Which statement explains how the changing arctic environment will most likely affect the population of arctic hares in winter

The population will decrease because environmental factors will reduce the ability of hares to hide from predators

The population will increase because environmental factors will increase the availability of food for hares.

The population will increase because genetic factors will increase the number of hares that survive and reproduce.

The population will decrease because genetic factors will reduce the ability of hares to survive in a warmer environment.

A student observes the map showing the tornadoes that were reported in April of 2019. Which impact would the student most likely observe in locations with reported tornadoes?

increased damage to buildings, structures, and trees

increased soil loss and desertification

decreased access to water storage and water bodies

decreased amount of dry land near rivers and streams

Major volcanic eruptions are examples of extreme events that leave behind the remains of living organisms that may form into rock layers. Scientists can use these rock layers to determine which organisms were alive at different times on Earth. Which statement describes the most likely location of a rock layer containing fossils of organisms living immediately before an extreme event occurred?

The rock layer directly beneath the volcanic eruption layer will contain fossils of organisms living immediately before the eruption occurred.

All the rock layers near the volcanic eruption layer will contain fossils of organisms living immediately before the eruption occurred

All the rock layers beneath the volcanic eruption layer will contain fossils of organisms living immediately before the eruption occurred.

The rock layer directly above the volcanic eruption layer will contain fossils of organisms living immediately before the eruption occurred.

The model represents a sound wave. Which statement best describes the relationship between matter and energy in a sound wave?

Energy in a sound wave transfers between particles of matter in a repeating pattern.

Particles of matter transform into energy to produce a sound wave.

Energy in a sound wave moves particles of matter from one place to another.

Particles of matter are transformed into other types of matter by energy in a sound wave

Some scientists study asteroids that could potentially impact Earth. Which mechanism could be used to best protect against this type of possible natural hazard?

rockets to push asteroids and change their direction and speed

satellites to calculate the mass and acceleration of asteroids

Doppler radar to measure the direction and speed of asteroids

probes to land on asteroids and detect their mass and acceleration
