Multiple Choice

An example of selective breeding is

• a dog breeder mating 2 dogs to make more dogs

• a farmer grows bees to pollinate the plants on his farm

• a person pollinates 2 white rose plants to only create white roses

Multiple Choice

Which of these is the first step in selective breeding flowers.

• Repeat the process only with the offspring with the desired traits

• watch the seeds grow

• Choose plants that have the desired trait to pollinate

• chose which trait is desirable

Multiple Choice

"Survival of the fittest" describes which theory

• Natural selection

• Selective breeding

Multiple Choice

Natural selection is where ___________ decides which traits should be passed on.

• nature

• a human

• traits

• evolution

Multiple Choice

Which is NOT a result of selective breeding?

• Large seedless watermelons that consumer demand

• Bright oranges that are all about the same size

• An insect that matches the color of the environment

• A dog that has been bred to have short hair

Multiple Choice

Artificial Selection is

• a new concept

• discovered by Darwin and used ever since

• used for thousands of years

• a 19th century concept

Multiple Choice

The change that occurs over long periods of time in the characteristics and diversity of organisms

• natural selection

• artificial selection

• evolution

• acquired characteristics

Multiple Choice

The primary difference natural and artificial selection is

• In nature selection the “pressure” comes from the environment; In artificial selection the “pressure” comes from humans (or another species).

• In artificial selection the “pressure” comes from the environment; In natural selection the “pressure” comes from humans (or another species).

• Natural selections is when humans breed the animal; Artificial selection is when humans direct genes directly.

• They are different terms for the same concept.

Multiple Choice

Which statement is true comparing natural selection and artificial selection?

• In natural selection, traits benefit humans and in artificial selection, the traits benefit the species

• In natural selection, traits benefit the species and in artificial selection, the traits benefit humans

• In natural and artificial selection, the process takes hundreds of years to occur

• In natural and artificial selection, nature determines what traits will be passed down to offspring.

Multiple Choice

Artificial selection is also known as

• natural selection

• selective hearing

• genetic manipulation

• selective breeding

• Harvesting stem cells

Multiple Choice

What is a good argument for genetically modifying animals?

• Produce more meat

• Modifying your kids to make them more awesome

• New genes are needed to create new species

Multiple Choice

What is risk of GMOs?

• Radioactive
• Food that taste too good
• throw an ecosystem off balance

Multiple Choice

Can biotech foods cause allergic reactions in some people?

• Yes, but only if people eat large quantities of the biotech food.
• Yes, if the biotech food contains a gene from a food known to cause an allergic reaction.
• No. Biotech foods are hypoallergenic.
• No, because food allergies are psychological and not physical.
