Hydroponics is a technique in which plants are grown using nutrients and water without the use of soil. This allows plants to be grown in places that plants cannot normally be grown, such as a desert. Which statement best explains why this is an example of biotechnology?

• Hydroponics uses math to solve everyday problems.

• It is a technique that improves one of the human senses.

• Biology and engineering are connected to meet human food needs.

• The success of hydroponics is used to measure success in all growing plants.

• to help other people solve the same problem

Which of these describes the work of engineers and the work of scientists?

• Engineers analyze data, and scientists do not.

• Scientists often work in teams, and engineers do not.

• Both are interested in understanding the natural world.

• Both follow a series of steps to find solutions to problems.
