A photograph of a litter of six-week-old bulldog puppies shows that the puppies are not identical. Even though these puppies have the same parents, they do not all look alike because —
they were produced by asexual cloning
some of the puppies have genetic material from only one of the
parents
each puppy has a different combination of genetic material as a
result of sexual reproduction
all the puppies developed from the same fertilized egg
A student was given this partial dichotomous key and asked to determine in which of five orders the adult insect shown belongs. Based on the dichotomous key, in which order does the insect belong?
Diptera
Isoptera
Ephemeroptera
Zoraptera
Buffelgrass is an invasive species of grass from Africa that
outcompetes native Texas grasses for space and water. Which
long-term change to a Texas grassland would most likely occur due to the introduction of buffelgrass?
The population of native grasses will increase.
The population of native grasses will decrease.
Buffelgrass offspring will develop traits like those of native
grasses.
Buffelgrass offspring will develop traits like those of other
invasive species.
Two plant species that grow in the same area are shown. Which statement best explains a difference between Plant 1 and Plant 2?
Plant 1 obtains more water from the soil because of its root
surface area and root depth.
Plant 1 obtains more sunlight because of its root surface area
and root depth.
Plant 2 obtains more water from the soil because of its root
surface area and root depth.
Plant 2 obtains more sunlight because of its root surface area
and root depth.
What function do both cell membranes and cell walls perform?
Producing energy for cellular processes
Allowing water to move into and out of cells
Synthesizing genetic material
Directing the reproduction of the cell
Students jump rope for one minute to determine changes in heart rate and breathing rate. Their data are shown in the table. Which table explains the functions of the two body systems that the students investigated?
Students observe an unknown species during a field study. They
observe that the organism is multicellular, is autotrophic, and can
reproduce both sexually and asexually.
Which kingdom does this organism most likely belong to?
Archaea
Animalia
Bacteria
Plantae
Humans depend upon food that comes from the ocean. Some
human activities negatively impact these food supplies. Which statement provides the best evidence that human activities contribute to this impact?
Human visitors to coral reef systems break corals growing on
rocks.
Humans catch marine fish at a faster rate than the fish are able
to reproduce.
Humans raise fish in a hatchery for commercial sale.
Humans construct artificial reefs to attract tourists.
Sea anemones and clown fish live together in the ocean. Which
statement best describes one way sea anemones depend on clown fish for an abiotic factor in an ecosystem?
Clown fish protect sea anemones from predatory fish.
Clown fish decrease competition among sea anemones.
Clown fish consume the remains of organisms paralyzed by sea
anemones.
Clown fish move water near sea anemones when dissolved
oxygen levels are low.
Trees lose water through transpiration, when water evaporates from leaves. The list describes types of tree leaves that help reduce the amount of transpiration. Which of these is most likely observed in an area experiencing a long-term drought?
Trees with broad leaves will be more healthy than trees with
needlelike leaves.
Trees with leaves that have waxy coverings will be more healthy
than trees without wax-covered leaves.
Trees with broad leaves will be more healthy than trees with
small, flat leaves.
Trees with leaves without any hair-like structures will be more
healthy than trees with leaves covered by hairlike structures.
A Texas Gulf Coast food web is shown. According to this food web, which organisms would the bobcat and diamondback rattlesnake compete for if the mouse population and swamp rabbit population decreased?
Raccoon and sparrow
Raccoon and Eastern cottontail rabbit
Sparrow and seeds
Sparrow and Eastern cottontail rabbit
