What is the function of bones? (2 reasons)
To protect and support our body

What is evolution?
Change in populations over time
200
These organisms eat to get energy. They cannot make their own food like plants.
Consumers

What is made during cell respiration?
ATP, water and carbon dioxide

What do proteins code for?
Traits!

What is the function of the digestive system?
To break down molecules and absorb nutrients into the blood stream
200
What three things cause evolution to occur?
Mutations, natural selection, and changes in the environment
300
If the predator population increases, what happens to the prey population? Why?
It decreases because more are being eaten.
300
What is made during photosynthesis?
glucose (food) and oxygen
300
What makes gametes?
Meiosis

What is the function of the respiratory system?
To inhale oxygen and exhale carbon dioxide.

Explain the natural selection of moths on dark trees.
(Explain using those three sentences!)
If the trees are dark, the dark moths will survive and reproduce because they will be able to camouflage. The light moths will die. Overtime, the whole population will be dark.

These organisms come into a new ecosystem and destroy it. What are these organisms called and why do they destroy the ecosystem?
Invasive species. They destroy it by either eating the native organisms, competing with the native organisms, or giving the native organisms diseases. Invasive species have no predators.
(Answers may vary)

Why do animals need plants?
Because plants make food and oxygen and animals can not live without food and oxygen!

How much of your DNA comes from each parent?
50%

What is the function of the heart?
To pump blood to our lungs and the rest of the body.

How does comparative biochemistry prove evolution?
When scientists compare DNA and amino acid sequences, they can see if the species are closely related or share a common ancestor. The more alike the organisms are, the more related they are. It shows the organisms evolved from a common ancestor.

Sea otters off the coast of California are experiencing a population crash. Give three reasons why this is happening.
Pollution is killing them- maybe they are choking on plastic bags.
Humans are killing them.
There is a new disease that is killing them.
Etc....

What causes cancer? Give at least 2 answers
1) Mutations that cause uncontrolled cell growth- mitosis forever.
2) Mutations can be caused by sunlight, smoking, alcohol, unhealthy diet, genetics, or they may just be random!

How are genetics and evolution connected?
Changes in DNA (mutations) is what causes evolution to happen. If that mutation is helpful, the organism will survive and reproduce and overtime the whole population will have that mutation.
500
Why do we need oxygen? Why do we need to get rid of carbon dioxide?
We need oxygen so our cells can do cell respiration and make ATP (energy). We need to get rid of carbon dioxide because it is made during cell respiration and it is a poison.

Why did humans evolve to have large brains? (3 sentences)
The humans with large brains were able to make tools that helped them survive and reproduce. The humans with large brains couldn't and died. Overtime, the whole population of humans had large brains.
