The Goby is a small fish that lives on other sea animals. The Goby gains food and protection yet offers nothing to the fish it lives on. This situation is an example of –
mutualism
parasitism
commensalism
predation
A student sets up a compost bin outdoors. Inside the bin microorganisms convert the student’s vegetable and paper scraps into rich fertilizer. Which of the following best describes the role that these microorganisms play in natural habitats?
The microorganisms help balance the numbers of producers and consumers.
The microorganisms help keep nutrients cycling through the ecosystem.
The microorganisms turn solar energy into sugars.
The microorganisms function as autotrophs.
The graph shows the number of taxa of reptiles whose fossilized tracks have been found. Which statement is best supported by these data?
Competition for food and shelter among reptile species was very low during the Triassic period.
A great extinction occurred during the Jurassic period.
Environmental conditions for speciation were most favorable for reptiles during the Permian period.
Reptiles adapted to a terrestrial environment during the Cretaceous period.
The diagram shows data on the evolution of horses. The data in the diagram is evidence that —
a new species of horse suddenly appeared
horses slowly developed over time
horses have similar stages of rapid embryological development
horses have a common ancestry with other hooved animals
A cladogram of five species is shown. Based on the cladogram, the ancestral species most likely had —
a vertebral column
a vertebral column and hair
sharp teeth and retractable claws
the ability to purr
Which statement is an example of how carbon moves through a food chain as part of the carbon cycle?
Producers release carbon dioxide, and consumers take it in.
Producers take in carbon dioxide, and consumers release it.
Producers take in carbon from the soil, and they release it when they decompose.
Producers release carbon into the soil, and consumers take it in from the soil.
What would be the most likely effect of a wildfire that burned a large area of a forest?
More sugars and starches would be available for animals in the area.
The availability of fossil fuels for use by industries in the area would be reduced.
Less carbon dioxide would be removed from the atmosphere in the area by plants.
An increase in animal respiration would increase the release of carbon dioxide in the area.
The diagram shows a partial East Texas food web. Which table correctly classifies these organisms?
A biomass pyramid of an ecosystem is shown. Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level?
Organisms at lower trophic levels outcompete organisms at higher trophic levels.
Organisms at higher trophic levels require smaller habitats than organisms at lower trophic levels.
Organisms at lower trophic levels provide less energy than organisms at higher trophic levels.
Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels.
The defenses of two flightless birds that live in different habitats are shown. How do the wings of the Gentoo penguin and the legs of the common ostrich provide an advantage in their habitat?
Allows them to find prey
Allows them to escape from predators
Allows them to control their body temperature
Allows them to be camouflaged in their environments
Researchers have observed striped hyenas and gray wolves hunting together in certain areas. One hypothesis suggests that changing hunting behavior aids both species in obtaining better and more resources. In this hypothesis the hyenas benefit because the wolves chase and take down large animals, such as goats, that the hyenas usually cannot catch alone. The wolves benefit from hyenas using their jaw strength to crack open large bones of prey to access additional nutrients from bone marrow. Which table best identifies the ecological relationships among the gray wolf, hyena, and goats?
Which statement best describes how bacteria recycle matter in an ecosystem?
Bacteria are producers that create energy for second-order consumers.
Bacteria produce toxins to prevent the growth of invasive species.
Bacteria cause diseases that limit the reproduction of organisms in a population.
Bacteria are decomposers that help to transfer organic material to the soil.
Students construct a graphic organizer to illustrate the different levels of biological organization. Which term does the letter X represent in the graphic organizer?
Organism
Cell
Ecosystem
Biosphere
Recent studies in bone research indicate that using ultrasound on a broken bone can decrease the healing time by 25%. Which of these are the most basic levels of organization involved when a bone heals?
Cells and organ system
Cells and tissue
Organ system and organism
Tissue and organ system
The human body is composed of organ systems. Which list represents a system organized from least to most complex?
•Heart
•cardiac muscle •muscle tissue
•muscle cell
•Lung tissue •trachea
•nostrils •circulatory system
•Nerve cell
•nerve tissue •spinal cord •nervous system
•Integumentary system
•skin cell
•hair
•sweat glands
A flower that has both male and female reproductive structures is shown. Which statement best describes an interaction that will allow a flowering plant to reproduce by self-pollination?
An anther is transferred from a filament to another filament within the same flower.
An ovule is transferred from the ovary to a petal on a different flower.
A pollen grain is transferred from an anther to the stigma of the same flower.
An ovary is transferred from a flower on one plant to a flower on a different plant.
Leaves are part of a plant’s shoot system. The xylem tissue in leaves transports —
the bacteria needed for nitrogen fixation in root nodules
the wax required to coat the surface of actively growing tissue
the water and minerals that are absorbed by the roots
the oxygen that regulates the rate of carbohydrate production
Plant hormones serve as chemical messengers between cells and tissues. Auxin is a plant hormone that causes the cells on the shady side of a plant shoot to elongate. The response enabled by auxin is known as —
geotropism
transpiration
phototropism
photosynthesis
Some students are instructed to put a celery stalk in a red dye solution for a lab activity. First the students carefully cut the bottom of the stalk with a scalpel. Then they put the stalk in the beaker with the solution and place the beaker on a shelf in the lab room. The next day they check the stalk and make observations. The students note that the leaves at the end of the stalk have changed color from green to red. The students cut across the celery stalk and use a hand lens to see that the small tube openings along the edge of the celery stalk are also red. The cross section is shown below. How do the plant systems work together to make this movement of liquid possible?
The roots absorb water and minerals and move them up to the stem, while the stem moves food produced in the leaves down to the roots in tiny tubes.
The roots absorb their own water and minerals, while the stem absorbs its water and minerals through the leaves.
The roots lose water vapor to the soil, and the stem loses water vapor through the leaves.
Cytokinins are a class of plant hormones that help regulate growth by promoting cell division. Cytokinins are produced mainly in meristematic tissue, where most plant growth occurs. Which system carries cytokinins produced in the roots to the rest of the plant?
Vascular system
Dermal system
Reproductive system
None of these
