This new predator runs faster than the native predators of
Which answer choice best describes a community?
Eight components present in nucleic acids are listed in the
What would be the most likely effect of a wildfire that burned a
large area of a forest?
Which four body systems interact to allow a person to sneeze?
Which cell that was viewed is most likely a prokaryote?
Based on this key, which two fish have eyes located on either side of
their head and are not spotted?
Students are modeling mRNA during the process of protein synthesis.
Which answer choice correctly describes the model of the mRNA strand
The chemical colchicine is used in the production of karyotypes. Colchicine prevents spindle fibers from forming during the cell cycle.
What is a result of preventing spindle fibers from forming?
A team of students encounters an unknown organism in a field while
conducting a biodiversity study. Some students think the organism is a
plant, while others think it is a fungus. Which question should the
students investigate to classify the organism correctly?
The San Marcos salamander, Eurycea nana, is a light reddish-brown
translucent salamander about 2–5 cm in length. E. nana is found only
in Spring Lake and a portion of the San Marcos River.
The data in the diagram is evidence that —
Which of these describes the similar functions of capsids and nuclear
Enzymes are proteins that have a three-dimensional shape that is
specific to a particular substrate. Environmental conditions can
change the shape of the protein.
Which description best identifies this type of cellular
Which selective pressure most likely resulted in the development of
the aye-aye lemur’s special adaptation?
Gibberellins are hormones produced in the root tips of plants. The
plant uses these hormones to stimulate the growth of shoots.
The populations of which organisms will most likely increase as a
result of a disease that suddenly reduced the population of Texas
Which statement provides the best explanation for the difference in
biomass of organisms found at each trophic level?
Conservation biologists studying cheetah populations have determined
that the lack of genetic diversity among the cheetahs is due to
CRISPR-Cas9 is a genetic modification technique that edits parts of
the genome of an organism. Using this technique scientists can add,
remove, or modify sections of the DNA sequence.
During secondary succession, which of these best describes why
decomposing pioneer plants give way to larger, more complex plants
species, such as hardwood trees?
Which two systems most directly interact in the fuzzy millipede’s
defense against ants?
Based on this pedigree, what are the most likely genotypes of
individuals I-1 and I-2?
G :(I-1: AA, I-2: Aa)
When cells lose their ability to regulate the cell cycle, they can
divide at an accelerated rate and form a mass of cells. This mass of
cells is referred to as —
Which type of mutation does the model demonstrate?
Many tree frog populations are threatened due to habitat loss. In an
effort to promote conservation, tree frogs may be bred in captivity. A
zoo acquired male and female tree frogs from two different
populations. In the zoo, the tree frogs were able to successfully mate
within their own population, but breeding attempts between the two
populations were unsuccessful.
In a study of physical endurance, researchers observed significant
increases in the heart rates and breathing rates of participants
immediately after they engaged in strenuous exercise.
In 1898 Friedrich Loeffler and Paul Frosch found evidence that the
cause of the highly contagious hoof-and-mouth disease in livestock was
a microscopic infectious particle. It was discovered that this
particle requires a host cell to reproduce.
Based on the two diagrams, which list correctly identifies the
Male guppies found in areas without predators are more colorful than
the ones found in locations with large predator populations. A
population of adult guppies originating from an area with a large
number of predators is transferred to a nearby area with few
Grassland ecosystems in Texas have evolved to depend on periodic
fires to return nutrients to the soil and encourage plant
reproduction. Humans have prevented fires in many of these grassland
areas, resulting in plant and animal communities with little
diversity. Wildlife biologists often recommend purposefully starting
fires called prescribed burns, which are monitored and controlled, in
grassland ecosystems every 3 to 4 years. These biologists observe
greater diversity in plant and animal life in the years following a
Which system interactions are dependent on the plant’s ability to
respond to the direction of light?
Exposure to the building material asbestos has been linked to certain
types of cancers. Asbestos causes mutations in the p53 gene, which
controls tumor suppression. Which statement best explains why people
with cancer due to asbestos exposure do not pass the mutation on to
Which of these components are found in the cells of all living
Based on this diagram, which two systems interact to maintain
Which role of protists has the most positive effect on maintaining
the plant population in an ecosystem?
Which list correctly matches the functions to the types of
Gametes produced by an organism contain a combination of genes from
that organism. In every gamete, this combination is —
What is the most likely explanation for white-tailed deer having a
seasonal breeding cycle instead of a monthly breeding cycle like many
