For an enzyme to be able to catalyze a reaction, the active site must -
cause the enzyme to be destroyed in the reaction
increase the activation energy level
be occupied by an inhibitor
have a complementary shape to the substrate
Snowshoe hares change coat color during the year. In the summer, when there is no snow on the ground, their coat is brown. In the winter when there is snow, their coat is white. Which describes the genetic basis for seasonal changes in coat color?
The snow causes mutations in the genes
The genes are regulated by hormone signals that are altered by changes in the environment
Sunlight causes cancer cells to develop
The genes are deleted during the summer

speed up
enzyme
proteins that speed up chemical reactions
active site
region of an enzyme where reactants bind
parasite
organism that lives and feeds on another organism for food
transition
changing from one state to another

Scientists can determine relatedness among organisms by comparing partial amino acid sequences. The table shows four partial amino acid sequences from four organisms.
Which organism is the LEAST related to the other three organisms?
Organism 1
Organism 2
Organism 3
Organism 4
Adaptations that result from natural selection are expected to increase the fitness of an organism. In terms of natural selection, which of the following best describes fitness?
Being able to escape from predators
Being among the strongest organisms in a population
Being able to survive, find a mate, and produce offspring
Being able to survive long enough to reach the adult stage
Which of these is a function of the cell membrane in all cells?
Producing cellular nutrients
Maintaining homeostasis
Neutralizing chemicals
Preserving cellular wastes
Which of the following is correct about the events of the cell cycle?
Little happens during the G1 and G2 phases of the cell cycle.
DNA replicates during the S phase of interphase.
Mitosis is usually the longest phase of the cell cycle when the cell is growing.
Interphase consists of G1, S, G2 phase and mitosis

AaBb
AABb
Aabb
aaBB
In cattle the allele for cloven hooves (H) is dominant over the allele for mule-foot hooves (h). The phenotype for each trait is shown in this picture.

25%
50%
75%
100%
Which statement about enzyme activity is best supported by this graph?
An enzyme must be composed of multiple polypeptides, or subunits, to be active.
An enzyme’s rate of activity increases with time until it becomes inactive.
An enzyme functions best under specific temperature conditions.
An enzyme works equally well in bacteria that are adapted to high temperatures and in eukaryotic cells such as human cells.
Which table correctly identifies the four most-abundant elements in biomolecules?
What is the purpose of this process this process?
To replicate the DNA of an organism before cell division
To assemble nucleotides in an mRNA chain along a DNA template
To synthesize amino acids used to unzip strands of DNA and copy the genetic code
To translate the genetic code into a specific sequence of amino acids
Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes?
Photosynthesis and cellular respiration both use carbon dioxide and release oxygen.
Photosynthesis and cellular respiration both use oxygen and release carbon dioxide.
Cellular respiration uses oxygen and releases carbon dioxide, while photosynthesis uses carbon dioxide and releases oxygen.
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
Which statement describes this model of DNA?
The model is inaccurate because the base pairs are incorrect.
The model is accurate because it contains correctly paired bases.
The model is accurate because it shows each base splitting to form a double helix.
The model is inaccurate because some typical bases in
DNA are missing.
Kingdom of unicellular organisms that are prokaryotic like bacteria, but lack peptidoglycan in their cell walls
Kingdom Archaea
Kingdom Bacteria
Kingdom Animalia
Kingdom Protista
Some students used vinegar to dissolve a way the shells of three eggs and used these eggs as models of human red blood cells. The students observed the changes in the eggs when they were placed in different solutions. Which statement best describes the role of the cell membrane in this model?
The cell membrane is an impermeable barrier that prevents water from entering the cell.
The cell membrane allows solutions to enter the cell, which causes the cell to shrink.
The cell membrane allows water to enter and leave the cell.
The cell membrane removes solutes from the environment.
An analysis of DNA and RNA sequences can be used to classify organisms. A dendrogram, such as the one shown, is based on molecular data. It can be used to represent evolutionary relationships within a group of organisms that are hypothesized to have descended from a common ancestor. Which statement is best supported by the information in this dendrogram?
Lesser pandas are more genetically similar to giant pandas than they are to raccoons.
Brown bears are more genetically similar to giant pandas than they are to sun bears.
Lesser pandas are more genetically similar to raccoons than they are to giant pandas.
The bear species are all more genetically similar to dogs than they are to giant pandas.
Food webs such as the one shown were first used in 1927 by the animal ecologist Charles Elton. The food web below represents the feeding relationships among organisms in an Alaskan ecosystem. An environmental change that removed which of these organisms from the ecosystem would cause the most instability in the ecosystem?
Auklets
Foxes
Salmon
Zooplankton
