Question 1

Food science is one area where biotechnology has made many advancements; however, many people are skeptical of some of the products produced through biotechnology. What argument best supports the idea that further biotechnological advancements in food sciences is beneficial for society?

a
Biotechnology is responsible for advancements in food science, which can make plants immune to various bacteria. The antibacterial compounds can affect people who consume the plant.
b
Biotechnology is responsible for advancements by creating plant varieties that are herbicide-resistant and pest-resistant. These plants make up most of the market, reducing the number of plant varieties people plant on the landscape.
c
Biotechnology is responsible for advancements that reduce the cost and resources needed for many different food products and allows people to produce more in a shorter amount of time.
d
Biotechnology is responsible for the reduced need for large-scale farms and traditional farming. Crops developed through biotechnological engineering can pollinate unmodified plants.
Question 2
Use the diagram below to answer the question.

The diagram shows a beaker of water and molecules of red dye at the beginning of an experiment (Time 1) and the same beaker of water and molecules of red dye after 30 minutes (Time 2). Which of the following best explains what happened?

a
Molecules of red dye moved by active transport from a higher concentration to a lower concentration.
b
Molecules of red dye moved by diffusion from a higher concentration to a lower concentration.
c
Molecules of water moved by active transport from a higher concentration to a lower concentration.
d
Molecules of water moved by osmosis from a lower concentration to a higher concentration.
Question 3
