Question
A student is investigating how different body systems work together to maintain homeostasis. The student finds that after eating a meal, the digestive system breaks down food into nutrients, and the circulatory system transports these nutrients to cells.
Which additional body system is directly involved in maintaining homeostasis in this process, and what is its role?
(5 Points)
The nervous system, which directs the movement of food through the digestive tract.
The respiratory system, which absorbs nutrients from the food.
The excretory system, which transports nutrients through the bloodstream.
The integumentary system, which stores nutrients for later use.
11.(7.LS1.5) During exercise, the body must regulate its internal conditions to maintain homeostasis. Which statement best explains how multiple organ systems work together to achieve this?
(5 Points)
The respiratory system increases oxygen intake, the circulatory system transports oxygen to muscles, and the excretory system removes carbon dioxide.
The digestive system increases nutrient absorption, the integumentary system stores oxygen, and the nervous system pumps blood.
The circulatory system absorbs oxygen, the digestive system removes carbon dioxide, and the nervous system transports nutrients.
The excretory system breaks down food, the musculoskeletal system filters blood, and the integumentary system moves oxygen.
12.(7.LS1.6) A researcher observes two populations of the same bird species living in different environments.
Population A lives in a dense forest and has darker feathers.
Population B lives in an open grassland and has lighter feathers.
Both populations hunt insects by perching on branches and watching for movement.
Which argument best explains how these differences in feather color affect survival and reproductive success?
(5 Points)
Birds with darker feathers in the forest are less visible to predators, increasing their chances of survival and reproduction.
Birds with lighter feathers in the forest survive better because they reflect more sunlight and stay cooler.
Birds with darker feathers in the grassland blend in better with their surroundings, making them more likely to catch prey.
Birds with different feather colors do not gain any survival advantage from their environment.
13.(7.LS1.6) A group of scientists is studying how desert plants survive in extreme conditions. They compare two plant species:
Plant X has deep roots and thick, waxy leaves.
Plant Y has shallow roots and thin leaves.
Which claim is best supported by scientific reasoning?
(5 Points)
Plant Y is better adapted to the desert because its thin leaves allow it to absorb more sunlight.
Plant X is better adapted to the desert because its deep roots reach underground water, and its waxy leaves prevent water loss.
Both plants are equally adapted to the desert because all plants need sunlight to survive.
Plant Y is better adapted because its shallow roots collect rainwater quickly.
14.(7.LS1.7) A scientist is studying two populations of bacteria.
Population A reproduces asexually by binary fission.
Population B reproduces sexually through the exchange of genetic material.
The scientist exposes both populations to an antibiotic.
After several generations, Population B shows more resistance to the antibiotic than Population A.
Which statement best explains this difference?
(5 Points)
Sexual reproduction produces genetically identical offspring, making Population B more resistant.
Asexual reproduction allows bacteria to mutate, making Population A more resistant.
Sexual reproduction creates genetic variation, increasing the chances of resistance in Population B.
Asexual reproduction results in stronger individuals, giving Population A an advantage.
15.(7.LS1.7) A farmer is deciding whether to plant crops that reproduce sexually through seeds or asexually through cloning. The farmer wants to ensure that the crops survive changing weather conditions.
Which argument best supports the use of sexually reproducing plants?
(5 Points)
Sexually reproducing plants produce identical offspring, making them more adaptable to changing conditions.
Asexually reproducing plants create genetic variation, increasing their ability to survive extreme weather.
Sexual reproduction increases genetic diversity, allowing some plants to survive environmental changes.
Asexual reproduction takes longer, making it better for long-term survival.
16.(7.LS1.8) A scientist is studying how mitosis helps organisms grow and repair damage. She observes the following events in a sample of skin cells:
A cut forms on the surface of the skin.
Neighboring cells begin to divide and produce new cells.
The new cells fill in the damaged area.
Which statement best explains how mitosis contributes to this process?
(5 Points)
Mitosis produces genetically identical cells, replacing damaged ones and restoring tissue function.
Mitosis creates genetically different cells, allowing the organism to adapt to the injury.
Mitosis removes damaged cells and does not produce new cells.
Mitosis only occurs when an organism stops growing, so it does not contribute to tissue repair.
17.(7.LS1.9) A scientist conducts an experiment to measure the amount of oxygen produced by a plant under different light conditions. She records the following observations:
Bright light: The plant produces a high amount of oxygen.
Dim light: The plant produces a lower amount of oxygen.
No light: The plant stops producing oxygen.
Based on this data, which conclusion best explains the relationship between photosynthesis and cellular respiration?
(5 Points)
Photosynthesis requires light to produce oxygen, which is then used by organisms for cellular respiration.
Cellular respiration occurs only when light is present because it depends on photosynthesis.
Photosynthesis and cellular respiration are the same process and occur at the same time.
Plants do not perform cellular respiration because they only make energy through photosynthesis.
Which additional body system is directly involved in maintaining homeostasis in this process, and what is its role?
(5 Points)
The nervous system, which directs the movement of food through the digestive tract.
The respiratory system, which absorbs nutrients from the food.
The excretory system, which transports nutrients through the bloodstream.
The integumentary system, which stores nutrients for later use.
