Which three statements correctly describe the roles of RNA molecules in the process of transcription and translation in animal cells?

Messenger RNA molecules carry genetic information from the gene in the nucleus to the ribosome in the cytoplasm.

Transfer RNA molecules carry the appropriate amino acid to the growing polypeptide.

Ribosomal RNA molecules function in the assembly of the ribosome-mRNA complex and in the formation of peptide bonds between amino acids in the growing polypeptide.

Small RNA molecules in the RNA polymerase catalyze the formation of phosphodiester bonds between nucleotides in the growing messenger RNA.

Genomic RNA molecules store genetic information and transmit it to an individual’s offspring.

Scientists sink concrete blocks in oceans to create artificial coral reefs. Which successive event most likely occurs first on this type of coral reef?

Coral polyps attach themselves to the surfaces to grow.

A researcher claims that glucose is moved into cells by facilitated diffusion through the GLUT4 transporter. Based on the model, which statement best supports the researcher’s claim?

The movement of glucose across the membrane does not require ATP.

Glucose moves from an area of low concentration to an area of high concentration.

The glucose molecules diffuse freely through the membrane without a protein channel.

Glucose provides energy for the protein channel to transport materials across the membrane.

When glucose is broken down, carbon dioxide is produced, which results in more carbon dioxide inside the cell than outside the cell. The carbon dioxide then diffuses out of the cell. Which statement best describes the movement of carbon dioxide by diffusion?

The carbon dioxide can move through the plasma membrane by moving down the concentration gradient.

Water molecules are needed to move the carbon dioxide across the plasma membrane.

Peripheral proteins help move the carbon dioxide across the plasma membrane.

The transport of carbon dioxide through the plasma membrane requires energy from ATP.

Coat color in dogs is controlled in part by a gene that regulates the deposition of pigment. The patches of color in the dog shown in the figure are caused by a somatic mutation. The genotypes in the different patches are indicated. Which three statements are true about the mutation that caused the black coloring?

The mutation will affect only this dog.

The mutation occurred in a body cell after the formation of the embryo.

The mutation made a permanent change to the DNA of the affected cell.

The mutation did not affect the phenotype of the dog.

The mutation was present in the gametes of the dog’s parents.

The graph shows the effect of temperature on the rate of an enzyme-catalyzed reaction in the presence of excess substrate. If the reaction temperature were to increase from 40°C to 63°C, the reaction rate would likely...

decrease, because the enzyme would become denatured.

increase, because the kinetic energy would increase.

decrease, because the enzyme would be used up

stay the same, because the rate of enzyme-catalyzed reactions is constant.

Which two factors can best explain the shape of the area labeled by a question mark on the population-growth curve?

There was competition among the birds for available resources.

Some birds were unable to find shelter from predators.

The population immigrated to a different geographical location.

A treatment for a communicable disease was given to the birds.

.A new food source was introduced to the birds.

Which two statements support the claim that viruses are nonliving?

Viruses lack machinery for reproduction.

Viruses cannot make their own chemical products.

Viruses contain a genetic code.

. Viruses contain structures made of proteins.

Which statement is the best explanation for the appearance of the flatwing phenotype among male crickets on Kauai?

A random mutation resulted in the appearance of the flatwing phenotype.

Crickets evolved the flatwing phenotype to escape detection by parasitic flies.

Infection by parasitic flies caused some crickets to mutate into the flatwing phenotype.

A change in female preference for mates resulted in the appearance of the flatwing phenotype.

The rate of cell division varies greatly in different types of human cells. The data table shows the replacement rates of many types of human cells. Which conclusion is most consistent with the data in the table?

Cells in the digestive system are among the most rapidly dividing cells in the body.

Cells in the integumentary system divide faster than any other type of cell in the body.

Cells of the respiratory and circulatory systems have faster replacement rates than cells of the digestive system.

Cells in the reproductive and nervous systems are never replaced.

Which statement describes an advantage of sexual reproduction over asexual reproduction?

Sexual reproduction results in more genetic variation in organisms than asexual reproduction

Sexual reproduction requires more time to produce organisms than asexual reproduction.

Sexually produced offspring are more dependent on their parents for survival than offspring produced through asexual reproduction.

Sexually produced organisms are more dependent on other organisms for reproduction than offspring produced through asexual reproduction.

In an investigation into the role of plants in the cycling of matter, a researcher is designing an experiment in which plants will be grown under conditions that will limit the rate of photosynthesis. Which design would match the goal of the researcher?

Grow the plants in a low carbon dioxide environment and measure the rate of oxygen production

Grow the plants in a low oxygen environment and measure the rate of carbon dioxide production.

Grow the plants in soil containing excess water and measure the rate of transpiration.

Grow the plants in soil containing excess nitrogen and measure the rate of plant growth.

Dialysis bags can be used as models of cells to explore the movement of materials into and out of cells. Students set up an investigation with a dialysis bag containing a 2% iodine solution in a beaker containing a 9% starch solution as shown in the figure. Starch turns blue-black in the presence of iodine. The dialysis bag is permeable to water and iodine but not to starch. Which two observations most accurately predict what will occur in the investigation?

The solution in the beaker will turn blue-black.

The mass of the dialysis bag will decrease.

The solution in the dialysis bag will turn blue-black.

The concentration of starch in the dialysis bag will increase.

The mass of the dialysis bag will increase.
