Module D Unit 2 Lesson 1

Multiple Choice

Why is understanding genetic change and traits important for studying evolution?

• It helps explain how species adapt over time.

• It is only relevant for plants, not animals.

• It does not affect the survival of organisms.

• It is unrelated to the concept of evolution.

Open Ended

How might mutations influence the traits that an organism inherits?

Multiple Choice

What is the definition of adaptation in the context of genetics?

• A learned behavior that helps an organism survive

• An inherited trait that improves survival and reproduction

• A physical change caused by the environment

• A temporary response to external conditions

Open Ended

How can a change to just one gene cause a lobster to be blue?

Fill in the Blanks

Inherited traits are passed on from parents to offspring by

material.

Multiple Choice

Which of the following traits can be inherited?

• Eye color

• Language spoken

• Musical taste

• Favorite food

Fill in the Blanks

In organisms that reproduce sexually, cells have pairs of

Open Ended

What is the role of DNA in determining traits and development in organisms?

Multiple Choice

Which of the following correctly describes the pairing of nucleotide bases in DNA?

• A pairs with T, G pairs with C

• A pairs with G, T pairs with C

• A pairs with C, G pairs with T

• A pairs with T, C pairs with G

Open Ended

Explain how genes are responsible for inherited traits in organisms.

Multiple Select

Which of the following statements about proteins is/are true?

• Proteins are made up of amino acids.

• A triplet of DNA bases codes for a specific amino acid.

• Genes carry instructions for making proteins.

• Proteins are made up of nucleotides.

Fill in the Blanks

A protein's

is linked to its function.

Open Ended

Describe how the folding and twisting of amino acid chains depend on the chemical structure of each amino acid.

Open Ended

How might the change in the folding pattern of the paper strip proteins relate to the genetic change that causes a lobster to be blue? Record your evidence.

Multiple Choice

How do changes in proteins affect the traits seen in organisms such as Labrador Retrievers?

• Proteins do not affect traits at all.

• Proteins only affect physical traits, not chemical traits.

• Different versions of proteins can result in different traits.

• Proteins only affect traits in plants.

Open Ended

Explain how genetic changes can lead to differences in physical characteristics, using the bush viper as an example.

Fill in the Blanks

A change in the base-pair sequence of a gene is called a

Multiple Select

Which of the following are examples of mutagens that can cause genetic mutations?

• UV radiation

• Chemicals in cigarette smoke

• Water

• Sunlight

Fill in the Blanks

Only mutations that occur in the DNA of

cells can be passed on from parent to offspring.

Open Ended

What are the connections between mutation, protein structure and function, and the lobster's blue color? Record your evidence.

Open Ended

How do you think mutations can affect the traits of an organism?

Multiple Choice

Which of the following best describes the role of DNA in living organisms?

• It provides energy for cellular processes.

• It contains the information that determines traits.

• It transports oxygen in the blood.

• It breaks down nutrients in the digestive system.
