The main function of this process is to
produce variations in cells before asexual reproduction
synthesize antigens needed to combat immunity
provide exact copies of the genetic code before cell division
make proteins needed for cellular metabolism
Which statement best explains how the message is delivered, even though these cells are not physically connected with each other?
The cells communicate with the use of chemical messengers between them.
The cells send messages by direct contact with other types of cells.
Nutrients are the primary means of communication between cells.
Ribosomes move out of one nerve cell into the other.
Kittens in the same litter often have similar characteristics, such as fur texture and markings, because they
were fed milk from the same mother
inherited similar genes
developed in the same environment
were born at the same time
Which three processes usually result in the greatest variety of possible gene combinations?
mutation, meiosis, and fertilization
differentiation, mitosis, and fertilization
cloning, meiosis, and fertilization
differentiation, mutation, and fertilization
In order to support the claim that the pollinators of the Venus flytrap are mostly flying insects, the researchers would
publish the study immediately and ask other researchers to support their claim
expand the study to other Venus flytrap habitats and determine the number of flying and nonflying insect remains found in the plants there
continue to study the insects found in the Venus flytraps in the research area, but only record the number of insects without wings
compare the kinds of insect bodies with and without wings found in pitcher plants, a plant similar to the Venus flytrap, with the kinds of insects found in the original study
Which graph would most accurately represent the relationship between the four kinds of bases found in DNA?
Which statement best represents the information shown in the graph?
Frogs tolerate more acidic conditions than the other organisms.
All nine species survive equally well in the same habitat, regardless of acidity.
Perch are more sensitive to acidic conditions than are snails.
Mayfly larvae and trout are equally sensitive to acidity.
Which sequence represents the correct interaction of organelles and processes for the synthesis of proteins?
nucleus → amino acid bonding → ribosomes → gene codes
ribosomes → nucleus → gene codes → amino acid bonding
ribosomes → gene codes → amino acid bonding → nucleus
nucleus → gene codes → ribosomes → amino acid bonding
What would occur if both structures labeled B were damaged or blocked?
The egg would remain in the uterus and not travel to the ovary.
The egg would not be able to unite with the sperm.
The reproductive cycle in the female would stop.
The process of mitosis would stop in the ovary.
Identify the structure that supports the development of the fetus and is also influenced by hormones.
A
B
C
D
Based on this and other similar studies involving newborns, medical professionals recommend that pregnant women avoid secondhand smoke because chemicals in the smoke
cause mutations in the cells of the ovaries
affect the growth of the fetus
are unable to pass through the placenta
decrease digestion in the stomach of the fetus
Even though these plants grow in different environments, they most likely control water loss through
the synthesis of proteins in their roots
the functioning of the cell membranes in their flowers
the actions of the guard cells in their leaves
the storage of glucose in the vacuoles in their stems
According to the graph, what is the minimum amount of folate needed to reduce the risk of neural tube defects to 10 or less per 10,000 births?
800 nmol/L
890 nmol/L
1000 nmol/L
1400 nmol/L
After an experimental study, during the peer review process, it was suggested that the experiment should be replicated. Explain why there is a need to replicate experiments and studies before conclusions are accepted by the scientific community.
State one laboratory procedure that would be used to make the organelles of onion cells on a wet mount slide more visible for viewing with a compound light microscope.
A sequence of mRNA bases that can produce a certain protein was found to be:
UUU GGG CCC AUA
Write the sequence of DNA that would produce this sequence of mRNA bases.
Which statement correctly describes an organism’s genetic information?
DNA molecules contain four subunits known as genes.
Chromosomes are made entirely of protein.
Genes are made of long sequences of chromosomes.
DNA contains combinations of four base subunits.
The removal of a short sequence of bases from a gene would most directly affect the
diffusion of materials into a cell
shape of a protein molecule
pH of the cytoplasm
size of a cell’s nucleus
The specialized function of this cell is most dependent on
mutations that produce cells that have a specific shape for filtering the blood
the differentiation of the cell membrane and the functioning of vacuoles
the DNA codes in the cell and the activity of ribosomes
mitochondria in the cell that produce filtering organelles for the kidney
The diagram below represents one of a number of different types of mutations that can occur in DNA.
This mutation can best be described as the
pairing of an adenine (A) base with thymine (T)
the insertion of an adenine (A) base into both strands of the DNA molecule
the substitution of an adenine (A) base for guanine (G)
deletion of an adenine (A) base from the DNA molecule
Which row in the chart below shows the connection between processes, structures, and hormones involved in the formation of an embryo?

Tree Surface Covered by Lichen (%) Which statement best describes the relationship between the nitrogen content and the growth of the lichen?
As nitrogen content in the lichen increases, the growth of the lichen increases.
As nitrogen content in the lichen decreases, the growth of the lichen decreases.
As nitrogen content in the lichen decreases, the growth of the lichen increases.
There is not a clear relationship between the amount of nitrogen in the lichen and growth.
Organisms living in a forest ecosystem rely on the Sun as a source of energy for metabolic processes. The following events occur as energy is captured by a plant and used in the metabolic processes of an herbivore.
The most likely order in which these events occur is
[A] – [D] – [B] – [C]
[D] – [A] – [B] – [C]
[B] – [A] – [C] – [D]
[D] – [B] – [A] – [C]

a decrease of 135 ppm
a decrease of 95 ppm
If a sequence of bases in DNA changes from TGA to TGG, would it result in a new inheritable trait? Support your answer.
No- the amino acid sequence will code for the same amino acid
No- the RNA would stay the same
Yes- The amino acid would be deleted
Yes- The amino acid would be different
