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.

A model of a bee pollinating a flower is shown. Bees cross-pollinate flowers when moving from flower to flower to obtain nectar. Bees use the collected nectar to create honey. Which three ecosystem services are best represented by this model?

provisioning services: goods provided by or produced by ecosystems

supporting services: services necessary for production of other ecosystem services

cultural services: nonmaterial benefits from ecosystems

land use: clearing land for human housing development

Which claim about the shark population is best supported using the data?

The population of sharks in Shark Bay is larger in the summer than in the winter.

More people fish for sharks in the winter than in the summer.

Sharks have larger body sizes during the summer than during the winter.

Sharks migrate northward from Shark Bay during the summer to maintain a low body temperature.

Deer mice rely on other organisms for many nutrients. The food deer mice consume is broken down into smaller particles, absorbed, and distributed throughout their bodies. One of these particles is glucose. Glucose requires specialized molecules such as the GLUT4 transporter to enter cells. Once glucose is in a cell, it can be broken down further to provide energy for the growth, metabolism, and maintenance of individual deer mice. Glucose entering a cell by way of GLUT4 is shown in the model. 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.

Which two statements support the claim that viruses are nonliving?

Viruses lack machinery for reproduction.

Viruses cannot ma k e 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? M. Cri

A r andom mutation resulted in the appea r ance of the flatwing phenotype.

Infection by pa r asitic flies caused some cric k ets to mutate into the flatwing phenotype.

A change in female preference for mates resulted in the appea r ance of the flatwing phenotype.

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? M. Grow the plants in

Grow the plants in a low o xygen e n vironment and measure the r ate of carbon di o xide production.

Grow the plants in soil containing e x cess w ater and measure the r ate of t r anspi r ation.

Grow the plants in soil containing e x cess nitrogen and measure the r ate 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 bea k er will turn blue-black.

The mass of the dialysis bag will decrease.

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

The mass of the dialysis bag will increase.

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.

Colorblindness is more common in males than in females because......

the allele for colorblindness is recessive and located on the X chromosome

fathers pass the allele for colorblindness to their sons only

the allele for colorblindness is located on the Y chromosome

males who are colorblind have two copies of the allele for colorblindness
