An endothermic process is a chemical process that absorbs energy in the form of heat. Frying an egg involves an endothermic process, as the egg absorbs heat energy from the frying pan. Any chemical process in which a substance takes heat from the surrounding environment is endothermic.
An exothermic process, by contrast, releases energy in the form of heat. Burning a log of wood involves an exothermic process, as the burning wood releases heat, ash, and smoke into the surrounding environment.

Question: Which term matches the picture?

Choices:
- exothermic process
- endothermic process

A population's growth is affected by factors in the environment, such as space, available food, predators, and disease. When a population inhabits an environment with abundant resources and few limiting factors, it can experience exponential growth. Under these conditions, a population grows increasingly rapidly. Plotted on a graph with time on the x-axis and population size on the y-axis, exponential growth resembles a J-shaped curve. Logistic growth, in contrast, occurs when resources are scarce or a population faces considerable limiting factors, such as predators. Logistic growth resembles an S-shaped curve: it rises steeply at first but then levels off. When growth levels off, the population has reached the environment's carrying capacity, or the population limit it can support.

Question: Which term matches the picture?

Choices:
- logistic growth
- exponential growth

Humans, like members of many other mammalian species, are monogastrics, which means that they have a single-chambered stomach. Some other mammalian species, though, are ruminants, which means that their stomachs have four chambers instead of one. Ruminants are perhaps most well-known for how much chewing they do during their digestive process. When a ruminant, such as a deer, eats food, the first two chambers of the animal's stomach extract the liquid from the food. The solid remainder of the food, known as the cud, is then regurgitated back into the animal's mouth to be chewed again. This allows the animal to extract more nutrients than it would otherwise. This is ideal for animals that eat plant-based diets, so it's no coincidence that ruminants are always herbivores.

Question: Which term matches the picture?

Choices:
- ruminant
- monogastric

When an animal dies, it still has valuable nutrients stored in its body. Helping return these nutrients to the ecosystem are detritivores and decomposers, both of which feed on dead organic matter. Detritivores, such as worms and some millipedes, eat and internally digest small chunks of dead organic matter. Decomposers, in contrast, often don't have mouths, so they must externally digest the dead organic matter. They break the matter into simpler parts, often dissolving it, and then absorb the broken-down matter. Fungi and bacteria are examples of decomposers. By breaking dead organic matter down, decomposers return some nutrients directly to the ecosystem. Other organisms also eat detritivores and decomposers, and nutrients return to the ecosystem in this way, too.

Question: Which term matches the picture?

Choices:
- decomposer
- detritivore

When immunologists develop a new vaccine, years of testing may be required before it is introduced to humans. Early testing may occur in vitro, or "in glass." In vitro testing is done outside of organisms, in a petri dish or test tube, and can help researchers identify the mechanism by which a vaccine works against a virus.
Another important form of testing that precedes human trials is in vivo testing. In vivo means "within the living." In vivo testing helps demonstrate how a vaccine works within the complex system that is a living organism; for example, a mouse might be given a vaccine and then exposed to a virus to show that the vaccine is effective.

Question: Which term matches the picture?

Choices:
- in vivo
- in vitro

Plants have different kinds of roots. Some plants, like grasses, have a mass of small roots, called fibrous roots. These roots usually don't go very deep. Instead, they spread from side to side, which helps plants like grasses cover more space. Other plants, like many root vegetables, have taproots. A taproot is a large main root, and smaller roots may shoot off from it. Both types of roots help plants collect water and nutrients from the ground, but taproots can reach much deeper.

Question: Which term matches the picture?

Choices:
- fibrous roots
- taproot

Marsupials and monotremes represent two unique subgroups of mammals. Marsupials, like most mammals, give birth to live young. Unlike other mammals, however, many marsupials carry their young in a pouch. Well-known marsupials include kangaroos, koalas, and possums.
Monotremes, on the other hand, do not give birth to live young; they are mammals that lay eggs! The only monotreme species alive today are the platypus, a semiaquatic duck-billed animal, and four species of echidnas, spiny creatures that look like porcupines with long noses.

Question: Which term matches the picture?

Choices:
- marsupial
- monotreme

There are two main types of plants: vascular and nonvascular. Vascular plants have tubes in their stems that bring water and nutrients to different parts of the plant. These tubes allow vascular plants to grow to be much larger, on average, than nonvascular plants. Nonvascular plants don't have these tubes. They are smaller, shorter, and often found near water, because water can't move through these plants as easily.

Question: Which term matches the picture?

Choices:
- vascular plant
- nonvascular plant

People can use the engineering-design process to develop solutions to problems. One step in the process is testing if a potential solution meets the requirements of the design.
The passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.

Dean was an aerospace engineer who was developing a parachute for a spacecraft that would land on Mars. He needed to add a vent at the center of the parachute so the spacecraft would land smoothly. However, the spacecraft would have to travel at a high speed before landing. If the vent was too big or too small, the parachute might swing wildly at this speed. The movement could damage the spacecraft.
So, to help decide how big the vent should be, Dean put a parachute with a 1 m vent in a wind tunnel. The wind tunnel made it seem like the parachute was moving at 200 km per hour. He observed the parachute to see how much it swung.
Figure: a spacecraft's parachute in a wind tunnel.

Question: Which of the following could Dean's test show?

Choices:
- if the spacecraft was damaged when using a parachute with a 1 m vent going 200 km per hour

People can use the engineering-design process to develop solutions to problems. One step in the process is testing if a potential solution meets the requirements of the design.
The passage below describes how the engineering-design process was used to test a solution to a problem. Read the passage. Then answer the question below.

People with diabetes sometimes take a medicine made from insulin. Insulin can be made by a special type of bacteria. Justine was a bioengineer who wanted to increase the amount of insulin that the bacteria produced by 20%. She read that giving the bacteria more nutrients could affect the amount of insulin they produced. So, Justine gave extra nutrients to some of the bacteria. Then, she measured how much insulin those bacteria produced compared to bacteria that did not get extra nutrients.
Figure: studying bacteria in a laboratory.

Question: Which of the following could Justine's test show?

Choices:
- whether she added enough nutrients to help the bacteria produce 20% more insulin
- whether producing more insulin would help the bacteria grow faster

Read the text about ant colonies.
Tiny ants live and work together in large groups called colonies. A single ant colony may have millions of ants living together in a nest with many tunnels and rooms. The queen ant is the head of the colony, but each ant in the colony has a job to do. The queen ant produces all of the eggs, while young female worker ants care for the eggs. Worker ants also dig tunnels and keep the nest clean. When they get older, some worker ants become soldier ants. Some soldier ants keep the nest safe and attack enemies. Others go out to seek food for the ants in the colony. When they find food, they bring it back to the nest. Each type of ant is important to the colony. Together, they can keep a colony going for hundreds of years.

Question: Which type of ant is the head of the colony?

Choices:
- the queen
- the solider
- the worker


Read the text about sloths.
Sloths are known for being one of the slowest animals on the planet. They also sleep up to twenty hours every day. Even though sloths are lethargic, they manage to stay safe by living in the treetops of South and Central America. Sloths have special qualities that help them spend their lives hanging from branches.
For example, sloths' long fur grows in the opposite direction from that of most animals. Most animals' fur grows downward, which helps rainwater run down off the animal. Sloths' fur, however, grows upward. When a sloth is hanging upside down, rainwater is still directed off its body. This helps the sloth dry off more quickly. Sloth fur has another special purpose. Each strand of fur has grooves that collect algae. The algae give the sloth a greenish color, which helps it blend in with its leafy environment. Along with sloths' slow movement, this disguise makes sloths hard for predators to spot.
Sloths also have long, curved claws on their front and back legs. Sloths can use their claws to protect themselves from predators. More importantly, the long, sharp claws curve around branches for a powerful grip. In this way, sloths' claws keep them from slipping and falling out of trees.
Hanging upside down all day can be hard for other reasons. In most animals, hanging would cause the stomach, heart, and other organs to press on the lungs. Not for sloths, though. Sloths have special bands of tissue called adhesions that help attach certain organs to the rib cage. These bands of tissue hold the organs in place so they don't press down on the sloth's lungs. Thus the sloth stays healthy and comfortable while hanging in its upside-down world.

Question: Based on the text, how does a sloth's fur help protect it?

Choices:
- A sloth's fur protects its important organs.
- A sloth's fur helps it hide from predators.
- A sloth's fur helps it cling to tree branches.


Read the text about singing dogs.
One dog begins howling. Others join in. Some of the howls are high, and some of the howls are low. So, when a group howls together, it can sound like singing. These unique sounds are made by New Guinea singing dogs, and they are quite different from the sounds other dogs make.
New Guinea singing dogs live in the mountains on the island of New Guinea. However, they are very shy and rarely seen. They look a lot like other kinds of wild dogs, but in some ways they are more like cats. They are great climbers and jumpers, and they groom themselves often to stay clean. Their eyes shine green in low light, just like cats' eyes do. These catlike singing dogs are one of a kind.

Question: Based on the text, where might you find these singing dogs?

Choices:
- at dog shows in America

Before sunrise on November 14, 1963, the crew of the fishing boat Isleifur II had just finished putting their lines in the ocean off the southern coast of Iceland. As the crew waited to have breakfast, a strong smell of sulfur drifted over the boat. At first, crew members thought that the cook had burned the eggs or that something was wrong with the boat's engine. But when the sun started to rise, the crew saw black smoke billowing from the water a few kilometers away.
The captain of the Isleifur II assumed the smoke was coming from a boat that was on fire, so he sailed closer to try to help. As the Isleifur II approached the smoke, the surface of the sea grew rough. The captain and crew saw flashes of lightning in the column of smoke and glowing pieces of molten rock shooting up out of the water. The captain realized this was not a burning boat. It was a volcano erupting under the water!
Figure: the erupting undersea volcano seen by the sailors on the Isleifur II.

Question: According to the text, what evidence of a volcanic eruption did the captain observe?

Choices:
- He heard a report on the radio warning about a volcanic eruption.
- He saw pieces of molten rock shooting out of the water.

Animals often behave in certain ways that can increase their reproductive success. Read the passage about a specific animal behavior. Then, follow the instructions below.

European earwigs are small insects that raise their offspring in cool, moist soil. After earwigs mate, females lay their eggs in underground nests. Females often groom, or clean, their eggs. The females lick their eggs and turn them over in the nest to groom them.
When female earwigs groom eggs, the eggs hatch more often. This is because grooming helps to remove mold from the surface of the eggs. Mold often lives in the soil around the nest and can infect and kill the eggs.
Figure: a female European earwig caring for her eggs.

Question:
Why might grooming eggs increase the reproductive success of a female European earwig? Complete the claim below that answers this question and is best supported by the passage.
Grooming eggs increases the chances that ().

Choices:
- the female will spend time near her offspring
- the female will produce more eggs

Animals often behave in certain ways that can increase their reproductive success. Read the passage about a specific animal behavior. Then, follow the instructions below.

Amazonian poison frogs live in tropical forests in northern South America. After a male and female frog mate, the female frog lays eggs on a plant. When tadpoles hatch from the eggs, the male frog lets the tadpoles climb onto his back. The male then searches for water trapped in the spaces where plants' leaves meet their stems. He puts his tadpoles in these small pools of water.
If the male frog puts a tadpole into a pool with a larger tadpole, the smaller tadpole is often eaten. So, the male frog usually puts each tadpole into a pool of water that does not have other tadpoles in it. Each tadpole lives in its own pool until it undergoes metamorphosis to develop into a frog.
Figure: an Amazonian poison frog carrying a dark-colored tadpole on his back.

Question:
Why might putting each tadpole in its own pool of water increase the reproductive success of a male Amazonian poison frog? Complete the claim below that answers this question and is best supported by the passage.
Putting each tadpole in its own pool of water increases the chances that ().

Choices:
- the male's tadpoles will be larger when they hatch
- the male will carry his tadpoles through the forest
- the male's tadpoles will become adult frogs


Animals often behave in certain ways that can increase their reproductive success. Read the passage about a specific animal behavior. Then, follow the instructions below.

Long-tailed sun skinks are lizards that live in southeast Asia. Most female skinks abandon their nests after laying eggs. But female skinks that live on a particular island with many egg-eating snakes behave differently. These skinks may guard their nests for several days after laying eggs.
When female skinks on the island guard their nests, fewer eggs are eaten by egg-eating snakes. If a female is at her nest when a snake approaches, she will attack the snake. Often, she can wrestle the snake out of her nest and away from her eggs.
Figure: a long-tailed sun skink.

Question:
Why might guarding the nest increase the reproductive success of a female long-tailed sun skink? Complete the claim below that answers this question and is best supported by the passage.
Guarding the nest increases the chances that ().

Choices:
- the female will lay more eggs
- the female will be injured by a snake

Animals often behave in certain ways that can increase their reproductive success. Read the passage about a specific animal behavior. Then, follow the instructions below.

Black-headed gulls build their nests on the ground. The gulls' eggs, chicks, and nests are brown, so they blend in with the sand, twigs, and dry grass around them. But the inside of a gull's eggshell is white. When an egg hatches, the white of the broken eggshell stands out from the brown nest. This makes it easier for crows and other predators to find the nest and eat the offspring in it.
After an egg hatches, the parent gull leaves the nest to carry the broken eggshell away. This helps the nest blend in with the environment again. It is harder for predators to find offspring in a nest that blends in with the environment.
Figure: a black-headed gull carrying a broken eggshell.

Question:
Why might removing broken eggshells from the nest increase the reproductive success of a black-headed gull? Complete the claim below that answers this question and is best supported by the passage.
Removing broken eggshells from the nest increases the chances that ().

Choices:
- the gull's chicks will get food
- the gull's offspring will survive
- the gull will be away from its offspring at a given time
