Bonus (optional, but encouraged): Write 5 full sentences about anything you have learned from these last two lessons! This is an opportunity for you to share with me anything you have learned that may not have been asked on this test!

Match the following terms and definitions!

Draggable item		Corresponding Item
Double Helix		The loose (spaghetti-looking) form of DNA
Genetic Factors		A piece of the compact (x-shaped) form of DNA.
chromatin		Things like weather, availability of food, or predators that can affect an organism's ability to survive.
chromosome		the production of offspring by a sexual or asexual process.
allele		The compact (x-shaped) form of DNA
Reproductive Success		a specific section of DNA
Environmental Factors		When organisms create offspring AND keep them alive!
gene		Traits that are passed on from parent to offspring and can affect the organism's ability to survive.
chromatid		the different ways a section of DNA can be coded
Reproduction		The twisted ladder shape of DNA

Which statement is true about genes?

They are composed of DNA

They control the inherited traits

Both A and B

None of the above

What is a nucleotide made up of?

A sugar, a phosphate, and a lipid

A sugar, a phosphate, and a base

A phosphate and a base only

A sugar and a phosphate only

What is the primary function of DNA?

None of the above

To store genetic information

To provide energy

To assist in cellular respiration

Which of the following is NOT a base found in DNA?

Cytosine

Guanine

Uracil

Adenine

Which of the following DNA sequences can be the other side of a DNA strand that has the following base sequence: ATCGCTAG

ATCGCTAG

GATCGCTA

UAGCGAUC

TAGCGATC

Draggable item		Corresponding Item
cytosine		thymine
thymine		cytosine

guanine		guanine

What does DNA do?

It determines how well we can read. 

It doesn't do anything.

It helps give our bodies instructions on how to build proteins, which give us our inherited traits. 

It just holds information that isn't really useful. 

What is the name of the general shape of a DNA molecule?

Draw it below!

Select all of that following that describe asexual reproduction.

Only takes one parent

Need to find a mate first, the raise the offspring to keep it safe.

Offspring are clones of the parent

Takes two parents

Usually slow

Needs help from nature to be successful (spreading pollen, seeds, etc.)

Usually fast

Offspring are different from that parents

Select all of that following that describe sexual reproduction.

Need to find a mate first, the raise the offspring to keep it safe.

Takes two parents

Only takes one parent

Usually fast

Offspring are clones of the parent

Offspring are different from that parents

Usually slow

Which might be an environmental factor that helps with reproductive success for a flower?

It rains just enough to give the plants the water that they need (but not too much).

Strong storms tear apart the land and rip up all of the plants.

A volcano sends tons of ash into the sky, blocking the sun from reaching the Earth's surface.

The flower has very pretty pedals that attract bees, which help spread the flower's pollen.

Which might be a genetic factor that hurts with reproductive success for an anteater?

An excessive amount of rain drowns out several ant colonies, limiting the anteater's food supply. 

It has fur that blends in with its environment so it is more able to hide from predators.

It has really short legs that doesn't allow it to run fast enough to outrun its natural predators. 

It has a really long nose that allows it to dig deeper into an ant colony and get more food.
