Which statement describes what will most likely occur in the rabbit population due to the introduction of the predator?
Slower rabbits will develop stronger legs and pass this trait to their offspring.
Faster rabbits will survive and reproduce increasing the average speed of the rabbit population.
Which answer choice best describes a community?
Three-spined sticklebacks living in estuaries
Different species of lizards occupying the same niche in a desert
Which components bond with Adenine [A] in a section of double-stranded DNA?
Deoxyribose sugar & Thymine Only
Adenine, Phospahte, Deoxyribose sugar & Thymine Only
What would be the most likely effect of a wildfire that burned a large area of a forest?
Less carbon dioxide would be removed from the atmosphere in the area by plants.
The availability of fossil fuels for use by industries in the area would be reduced.
Which four body systems interact to allow a person to sneeze?
Muscular, immune, nervous, respiratory
Nervous, respiratory, circulatory, skeletal
Which cell that was viewed is most likely a prokaryote?
W
X
Y
Z
Which answer choice correctly describes the model of the mRNA strand being transcribed?
The mRNA strand is complementary to the DNA template strand; however, uracil instead of adenine is paired with thymine.
The mRNA strand is complementary to the DNA template strand; however, uracil instead of thymine is paired with adenine.
What is a result of preventing spindle fibers from forming during cell cycle?
Mitotic division stops in metaphase and cannot proceed to anaphase.
The cell cycle skips G phase and repeats G phase. 0 1
A team of students encounters an unknown organism. 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?
Is there a cell wall around the cells of the organism?
Does the organism perform photosynthesis?
The San Marcos salamander, Eurycea nana, is found only in Spring Lake and a portion of the San Marcos River.
Which human activity would most likely decrease the ability of the salamanders to survive?
Increasing water consumption that decreases the flow of clean water from the springs that feed the river
Public transportation that reduces the number of automobiles that contribute to pollution runoff into the river
The data in the diagram is evidence that —
a new species of horse suddenly appeared
horses slowly developed over time
Which of these describes the similar functions of capsids and nuclear membranes?
Both protect genetic information for the structures.
Both code for the proteins needed for reproduction of the structures.
What is the most likely result if the shape of the enzyme changes?
The substrate will change its shape to match the enzyme.
The enzyme will no longer be able to catalyze the reaction with the substrate.
Which description best identifies this type of cellular transport?
Active transport, because energy is being used to move molecules against the concentration gradient
Facilitated diffusion, because energy is being used to move molecules with the concentration gradient
Gibberellins are hormones produced in the root tips of plants.
The plant uses these hormones to stimulate the growth of shoots. How are gibberellins able to affect other parts of the plant?
Gibberellins are absorbed through the stomata and attach to chloroplasts.
Gibberellins are transported through vascular tissues to other parts of the plant.
Which other molecule is a product of this process?
DNA
RNA
C6H12O6
ATP ENERGY
Which statement provides the best explanation for the difference in biomass of organisms found at each trophic level?
Organisms at higher trophic levels have less energy available to them than organisms at lower trophic levels
Organisms at higher trophic levels require smaller habitats than organisms at lower trophic levels.
Using this CRISPR-Cas9 technique scientists can add, remove, or modify sections of the DNA sequence.
How can scientists use this technique to control gene expression?
By activating or deactivating specific genes
By calculating the number of genes different organisms produce
By identifying how closely related one individual is to another
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 —
A tumor
an embryo
a gland
an organ
Which type of mutation does the model demonstrate?
Deletion
Insertion
Substitution
Breeding/Reproduction attempts between the two different populations WILL NOT BE successful.
This shows that............................
They are in the same family but different orders.
They are in the same genus but different species.
Hoof-and-mouth disease in livestock is caused by a particle that requires a host cell to reproduce.
Which pathogen is most likely responsible for this disease.
A bacterium, because it is contagious
A protist, because it is microscopic
A virus, because it requires a host cell to reproduce
Which of these components are found in the cells of all living organisms?
Cytosine and guanine
Cellulose and chlorophyll
