Engineers are working to develop a new kind of artificial knee, which is used to replace damaged knees. Which of these would be considered a trade off of the artificial knee?
A. The artificial knee reduces pain in people who have the knee.
A. The new artificial knee is heavier than previous artificial knees to improve its lifespan.
A. The artificial knee can lead to infection when the knee is implanted.

1. Scientists are developing a new class of vaccines, known as nanovaccines, which can be stored at room temperature for six to ten months. A study found evidence that nanovaccines boost the immune response in mice. The scientists reported their initial findings to other scientists. What is the most logical next step in the nanovaccine development process?
A. determine the best way to ship large amounts of the vaccine
A. produce larger quantities of vaccine for distribution by medical professionals
A. replicate the nanovaccine results in further animal studies
1. Which steps will reduce the amount of an input to photosynthesis? Circle the letters of all the correct answers.
A. cover half of the plant’s stomata
A. place the plant in a low-oxygen environment
A. increase the carbon dioxide levels of the plant
1. A researcher is comparing sugar molecules that a cell takes in with amino acid molecules that the cell produces. Circle the letters of the statements that are true about amino acids but not about sugars.
always contain carbon
B. is an input in glycolysis
B. structure is coded for in DNA
B. can be used as an energy source
Which statement is accurate when comparing the reactants with the products? Circle the letter of the correct answer.
The reactants have more mass than the products.
B. The reactants form more quickly than the products.
B. The bonds of the reactants contain more energy than the bonds of the products.
1. A graph is created to show the energy changes occurring when breaking the polymer into two monomers. How would that graph differ from the one shown? Circle the letter of the correct answer.
A. In the new graph the products would have more energy than the reactants.
B. In the new graph the products would have less energy than the reactants.
B. In the new graph the enzyme would increase the activation energy required.
1. Using the information in the graph, circle the letters of all the correct statements.
A. Energy is absorbed in this reaction.
More energy would be released than absorbed in the reaction.
B. The enzyme raised the activation energy required for the reaction.
1. Carbon dioxide from the atmosphere is dissolved in the seawater. Which process uses this dissolved carbon dioxide?
A. photosynthesis by oceanic fish
A. photosynthesis by phytoplankton
A. aerobic respiration by marine mammals

A. The cells did not have enough oxygen.
A. The cells did not have enough glucose.
The cells had too much carbon dioxide.
1. Which statement explains the movement of energy through aerobic cellular respiration?
A. Heat energy is absorbed as chemical potential energy is transferred from oxygen molecules to ATP molecules.
A. Heat energy is released as chemical potential energy is transferred from oxygen molecules to ATP molecules.
A. Heat energy is released as chemical potential energy is transferred from glucose molecules to ATP molecules.
1. Alicia is making a model of photosynthesis and respiration. Which statement describes the role of glucose in Alicia’s model?
A. Oxygen is an output for both respiration and for photosynthesis.
A. Glucose is an input for respiration and an output for photosynthesis.
-A. Carbon dioxide is an input for respiration and an output for photosynthesis.
