The graph below shows the global concentration of carbon dioxide in the atmosphere over Earth's recent history. Scientists agree that increased concentrations of carbon dioxide in Earth's atmosphere have caused global temperatures to rise over time. Many species can only survive within a certain temperature range. For this reason, species that are unable to adapt to rising temperatures may eventually become extinct. A solution designed to preserve Earth's biodiversity could include

• Reducing the total amount of carbon dioxide entering the atmosphere.

• Supporting natural and artificial processes that extract carbon dioxide from the air.

• Placing critically endangered species in climate-controlled environments.

• All of these

The embryonic developmental stages of five animal species are shown in the diagram below. The beginning developmental stages of all five species are very similar, including the presence of gills in each one. As they continue to develop, however, distinct differences become obvious. What does this imply about these species?

• These species share a distant common ancestor.

• These species all evolved from a single reptilian ancestor.

• These species all have identical DNA sequences.

• These species do not share any common ancestors.

Genetic engineering is used in agriculture to create genetically modified organisms, such as crop plants that are more resistant to disease. Which of the following describes a possible risk of genetically modifying a crop species?

• A decrease in the genetic diversity of the crop species

• A decrease in the amount of pesticides that need to be used on the crop

• An increase in the amount of the crop that is harvested each year

• An increase in the ability of the crop species to survive harsh conditions

Meiosis is necessary for sexual reproduction. During this process, four daughter cells are produced from a single parent cell. The daughter cells produced through meiosis

• Contain the same number of chromosomes as the parent cell.

• Do not contain any chromosomes until after fertilization.

• Contain half the number of chromosomes as the parent cell.

• Contain twice the number of chromosomes as the parent cell.

The diagram below shows a single bacterial colony before, shortly after, and one hour after exposure to an antibacterial gel. Which statement best explains why the antibacterial gel did not eliminate the entire bacterial colony?

• Exposure to the antibacterial gel caused some of the bacteria to become highly resistant to its effects.

• Natural resistance to the antibacterial gel allowed most of the bacteria in the colony tosurvive the treatment.

• Inconsistent application of the antibacterial gel caused some of the bacteria to receive a lower dose than others.

• Genetic diversity within the bacterial colony allowed some of the bacteria to survive the treatment and reproduce.

A typical cell has different organelles that each have a unique function. For example, mitochondria produce energy, ribosomes synthesize proteins, and endoplasmic reticulum transports proteins. Why do cells contain different organelles?

• Different organelles act independently of one another because each organelle can carry out all of the functions of a cell.

• Different organelles act independently of one another so that the whole cell can function as the basic unit of life.

• Different organelles interact as a system so that the whole cell can function as the basic unit of life.

• Different organelles interact as a system because each organelle can carry out all of the functions of a cell.
