100
The process in which species change over time.
What is evolution?
100
When there are too many offspring for the available resources.
What is overproduction?
100
This is how a new combination of genes is made.
What is sexual reproduction?
100
This is what the tympanic membrane does.
What is hearing for the frog?
100
This is the first site of digestion.
What is the stomach?
200
Natural differences between organisms of the same species.
What is variation?
200
This is another word for when the adaptation is being passed on to the next generation.
What is selection?
200
This is when DNA is copying itself and it makes an error, introducing a new form of a gene.
What is mutation?
200
This is what the eustachian tubes do?
What is relieves pressure from the ears?
200
This is where the blood is filtered and it is the largest organ in the frog.
What is the liver?
300
A characteristic that helps an organism survive and reporoduce in its environment.
What is adaptation?
300
These are the four parts of the theory of natural selection in order.
What is overproduction, variation, adaptation, and selection?
300
This is an example of a variation.
What is (any answer that is a difference within the same species)?
300
This is the structure that connects the mouth with the stomach.
What is the esophagus?
300
This organ has three chambers.
What is the heart?
400
Organisms that can breed with each other and produce fertile offspring.
What is a species?
400
When there are too many offspring for the resources available, it causes this.
What is competition?
400
This is who came up with the theory of natural selection.
Who is Darwin?
400
This is the part that brings oxygen down to the lungs and helps the frog to vocalize.
What is the glottis?
400
This part is found only on male frogs.
What is the testes?
500
When members of a species that are best suited to their environment survive, reproduce at a higher rate and therefore pass on their genes more than other members of the species.
What is natural selection?
500
Come up with a way that an elephant could have gotten such a long trunk that is in line with natural selection.
What is the elephant's ancestor with the variation of a slightly larger upper lip was able to reach more leaves off of trees, so it was able to pass on its genes. This continued until it became a trunk.
500
These are the reasons that variation is so important.
What is without variation, there would have only been one type of living thing on Earth since it is how species change. Also, entire species could be wiped out by viruses, or over-hunted if they were not so well suited to their environment.
500
This is the job of the teeth of the frog.
What is holding prey (not chewing as they don't chew)?
500
These two parts are found only on female frogs.
