Which organelle stores the genetic material needed to produce proteins?

• cell wall

• nucleus

• plasma membrane

• ribosome

Which statement correctly identifies a similarity between prokaryotes and eukaryotes?

• Both have circular chromosomes

• Both are very large in size

• Both contain more than one cell

• Both contain ribosomes

The diagram shows an experimental setup where different glucose solutions are separated by a semipermeable membrane. Which question can be answered with the results from this experiment?

• What is the function of glucose molecules in the body?

• How do two solutions with different concentrations attain equilibrium?

• What are the factors that decide the rate of dissolving glucose in a solution?

• How are high-concentrated solutions different from low-concentrated solutions?

Based on the graph, a student claims that atmospheric carbon dioxide concentration affects the global temperature. Is the claim made by the student supported by the data?

• Yes. Global temperature increases as carbon dioxide concentration increases.

• Yes. Global temperature decreases as carbon dioxide concentration increases.

• No. Global temperature increases as carbon dioxide concentration remains the same.

• No. Global temperature remains the same as carbon dioxide concentration increases.

Tiger sharks and hammerhead sharks both feed in the same coastal water systems off of Florida. They typically do not interact with each other directly but feed on the same piscine living in the area, such as other small sharks, bony fish, lobsters, and rays. Which term best describes their interactions?

• predator-prey

• parasitism

• mutualism

• competition

Golden lion tamarins, which are known for their vibrant golden fur, are native to the Amazon rainforest. The image shows a golden lion tamarin that lives in trees and has a diet of fruits, insects, nectar, small vertebrates, and tree sap. A major issue threatening the golden lion tamarins is loss of their habitat due to deforestation. The increase in human activities, such as farming, logging, and mining, is the major cause of deforestation in the Amazon rainforest. In the golden lion tamarins' effort to adapt to the drastic environmental changes resulting from rapid habitat loss, what is the most probable outcome?

• The golden lion tamarins are likely to face extinction.

• The golden lion tamarins will have new types of predators.

• The golden lion tamarins will have an increased average lifespan.

• The golden lion tamarins might migrate to desert regions.

The pedigree chart shows the inheritance of a disease in a family. Which analysis supports the argument that the disease is sex-linked?

• The son can be treated for the disease.

• Both daughters of an affected father are carriers for the disease.

• There are more females with the disease in the family.

• The disease is only seen in the second generation.

Scientists design a plasmid to allow bacteria to produce insulin. They insert the gene for insulin production along with a gene for resistance to the antibiotic tetracycline and another gene that makes the bacteria glow green under ultraviolet light. To produce bacteria that can make insulin, the scientists add the wild plasmid to a bacterial culture during transformation. If the bacteria acquire the plasmid, under which conditions could the scientists identify the bacteria that can produce insulin?

• Use a growth medium with the antibiotic tetracycline and a normal white light.

• Use a growth medium with the antibiotic kanamycin and a normal white light.

• Use a growth medium with the antibiotic tetracycline and an ultraviolet light.

• Use a growth medium with the antibiotic kanamycin and an ultraviolet light.

Genetically modified (GM) Atlantic salmon is designed to contain the growth hormone gene from a Chinook salmon and the growth hormone's expression-controlling gene from a different type of fish, an eelpout. These genes allow a GM Atlantic salmon to grow year-round instead of only during the summer months. The goal is to help reduce hunting of wild Atlantic salmon for human consumption. Although the GM Atlantic salmon will breed humans, there is concern about the modified fish escaping into the natural ecosystem. Which is a likely ethical issue if GM Atlantic salmon escape into the natural ecosystem?

• The GM Atlantic salmon might share migration patterns with other fish.

• The GM Atlantic salmon might resist breeding with other fish species.

• The GM Atlantic salmon might outcompete native fish for space and food.

• The GM Atlantic salmon might become the preferred food for predatory fishes.

Several insect species live in an area. An insecticide is sprayed in the area to control the population of mosquitoes. The diagram shows a change in a non-target moth population before and after the insecticide is used. The different moth colors in the diagram represent variation in traits. Which argument can be made about the use of the insecticide?

• The insecticide transfers traits from mosquitoes to moths.

• The insecticide reduces the gene frequency of certain traits within the moth population.

• The insecticide causes mutations to different traits in the moth population.

• The insecticide provides additional protection for the moth population from predators.
