Norman Borlaug and the Green Revolution

In order to understand the importance of using biotechnology in crop improvement, and how pivotal this has been for our world, you must learn about the Green Revolution which began in the 1930's before we has GMOs.

Multiple Select

During the Green Revolution, crops yields were increased by which of the following advances in biotechnology? (Mark ALL that apply)

• better irrigation of farmland

• wheat bred to grow really well in hot environments, such as Mexico and India

• genetically modified wheat that was resistant to pests

• more efficient use of pesticides

Multiple Choice

What is the oldest form of biotechnology?

• natural selection

• GMOs

• gene therapy

• artificial selection

Multiple Choice

Which of the following is an example of artificial selection?

• A species evolving to withstand cold environments

• A person breeding dogs for long, thick coats

• A species of plant becoming extinct

• A snake blending in with its environment

Multiple Choice

A transgenic crop is a plant that has genes from a different _______ artificially inserted into its genome
