A form of artificial selection to produce offspring with specific traits

What is the evidence for evolution?

Fossils, comparative anatomy, molecular biology, and biogeography.

What is a structural adaptation?

Physical features of an organism that help it survive.

What are two similarities between artificial selection and genetic engineering? (2 right answers)

Both involve manipulating organisms to achieve desired traits., Both involve altering an organism’s DNA

What is a behavioral adaptation?

Behaviors that help an organism survive

Define natural selection

When organisms with favorable traits survive and reproduce.

How can scientists use genetic engineering to solve the problem of insecticide resistance?

They make mosquitoes with a gene that makes offspring die

Bt corn (resists pests) and Golden rice (produces vitamin A).

What is artificial selection?

The process of selecting and breeding organisms with desirable traits

What is genetic engineering?

The manipulation of an organism’s DNA to achieve desired traits.

What was the main contribution of Darwin to modern Science?

Darwin’s theory of natural selection how species evolve from the environmen

What makes an organism a GMO?

Things whose DNA has been altered through engineering to get desired traits

How did genetic engineering make a breakthrough in medicine?

Inserting the insulin gene into bacteria to produce insulin for diabetics

Questions 25

Answers

1
How do organisms adapt to their environments?
By changing traits instantly in response to the environment.
By acquiring traits during their lifetime and passing them to offspring
Organisms adapt by avoiding environmental changes altogether
Through natural selection, where beneficial traits become more common
2
Why do humans selectively breed animals?
To make animals evolve randomly over generations
To make animals with desired traits,like better health, size, or appearance
To create animals that can survive in any environment without adaptation
To ensure animals remain the same as they were in the wild
3
What are analogous structures?
Structures with the same origin and the same function in different species.
Structures that are identical in all species.
Different structures but similar functions in different species
Structures used for the same function but evolve in the same species.
4
What was the organism that captured Darwins attention on the Galapagos islands?
The finches on the Galapagos Islands.
The tortoises on the Galapagos Islands.
The iguanas on the Galapagos Islands.

5
What are two differences between artificial selection and genetic engineering? (2 right answers)
Selection breeds things for traits, while engineering alters the DNA
Selection is breeding over generations,while engineering does it in the lab
Selection occurs naturally, while engineering is done by nature

7
What are homologous structures?

9
What was Lamarck’s theory? Refute his theory by evidence!
Organisms evolve by adapting to their environment instantly

Temporary changes in an organism’s body in response to the environment
13
What are two similarities between artificial selection and genetic engineering? (2 right answers)
Both involve manipulating organisms to achieve desired traits.
