[{"role": "user", "question": "Which term matches the picture?", "answer": "", "options": {"A": "logistic growth", "B": "exponential growth"}, "choices": ["A", "B"], "hint": "Read the text.\nA 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."}] | 447 | |
[{"role": "user", "question": "Which term matches the picture?", "answer": "", "options": {"A": "ruminant", "B": "monogastric"}, "choices": ["A", "B"], "hint": "Read the text.\nHumans, 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."}] | 450 | |
[{"role": "user", "question": "Which term matches the picture?", "answer": "", "options": {"A": "decomposer", "B": "detritivore"}, "choices": ["A", "B"], "hint": "Read the text.\nWhen 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."}] | 451 | |
[{"role": "user", "question": "Which term matches the picture?", "answer": "", "options": {"A": "in vivo", "B": "in vitro"}, "choices": ["A", "B"], "hint": "Read the text.\nWhen 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.\nAnother 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."}] | 455 | |
[{"role": "user", "question": "Which term matches the picture?", "answer": "", "options": {"A": "fibrous roots", "B": "taproot"}, "choices": ["A", "B"], "hint": "Read the text.\nPlants 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."}] | 476 | |

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.\nMonotremes, 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."}] | 479 | |

These types of muscles are called striated muscles. If you look at them under a microscope, the cells appear rectangular and striped. There are other kinds of muscles, though, called smooth muscles. The cells that make up smooth muscles are oval shaped and not striped. They are found in places like the digestive system, where they help to keep food moving."}] | 489 | |

Read the passage. Then answer the question below.\n\nDean 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.\nSo, 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.\nFigure: a spacecraft's parachute in a wind tunnel."}] | 246 | |

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.\nFor 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.\nSloths 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.\nHanging 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."}] | 392 | |
