Gene
What term describes all living and nonliving things interacting in one area?
Ecosystem
What system transports oxygen and nutrients through the body?
Circulatory system
This animal has three hearts and blue blood!
octopus
What structure controls what enters and leaves the cell?
Cell membrane
What are the possible genotypes for a homozygous dominant organism?
Two dominant alleles (AA)
What happens to energy as it moves up a food chain?
It decreases — only about 10% is passed on
Which organ filters blood and produces urine?
Kidneys
The strongest muscle in your body (for its size) is found here.
tongue
In plant cells, what is the function of chloroplasts?
Photosynthesis — converting light energy into chemical energy
If a dominant allele is present, this is what happens to the trait.
What is the dominant trait shows up?
This is the original source of energy for almost all ecosystems on Earth.
Sun
These organs take in oxygen and release carbon dioxide when you breathe.
Lungs
This animal can sleep for up to three years without eating.
snail
This structure is found in plant cells but not in animal cells and helps the plant keep its shape.
cell wall
The tool scientists use to predict possible genetic outcomes of a cross is called this.
Punnett square
When several food chains are connected together, they form this.
food web
What is the heart?
Muscles
Chickens are the closest living relatives of these ancient reptiles.
dinosaurs
This organelle is responsible for packaging and transporting proteins out of the cell.
Golgi apparatus (or Golgi body)
DNA provides the code for making these molecules that build and repair the body.
proteins
The process by which carbon moves between the atmosphere, plants, animals, and the Earth is called this.
carbon cycle
The body’s ability to maintain stable internal conditions, like temperature, is called this.
homeostasis
Why do your ears “pop” when you go up a mountain or in an airplane?
Air pressure changes cause your eardrum to adjust
