Do fossils have to be complete organisms? Explain.
What is no, because they can just be an imprint if minerals get into the organism.

Explain how an organism can adapt to hunting.
What is answers will vary. Ex: elephants are born without tusks
100
Give an example of a nonrenewable resource.
What is answers will vary. Ex: coal
200
What is the number and variety of organisms in a given area during a specific period of time.
What is biodiversity
200
What are the two ways to compare organisms?
What is comparing skeletal structures and comparing DNA molecules.
200
What did Charles Darwin notice about the finches in the Galapagos Islands?
What is the finches have different sized beaks due to adapting to their environment.
200
How can competition for mates be part of natural selection?
What is animals adapt to have characteristics to attract a mate.
200
Why can exotic species be considered negative?
What is they can be considered pests and compete with native species.
300
What is the process by which individuals that are better adapted to their environment survive and reproduce more successfully than less well adapted individuals do.
What is natural selection.
300
Explain why species change over time?
What is as earth and an organism's environment changes, the organisms have to adapt to it.
300
Why would farmers want to use selective breeding?
What is to create plants or farm animals that have better traits.
300
How is insecticide resistance a survival characteristic?
What is so insects with this trait can survive long enough to pass this trait on to their young.
300
Name 2 types of pollution.
What is noise, garbage, chemicals, high-powered wastes, and gases.
400
In a fossil record, which organisms are most common?
What is in the layers next to each other.
400
What evidence do fossils provide about the ancestors of organisms?
What is they may show the parts of an organism to compare them to common day organisms.
400
What knowledge that modern scientists now use to explain how variation occurs did Darwin lack?
What is Darwin lacked the knowledge of genetics that helps explain how organisms inherit traits and why there is so much variety in organisms.
400
Suggest an organism other than an insect that might develop an adaptation to human activities.
What is answers will vary. Ex: rodent.
400
Why is deforestation such a problem?
What is it gets rid of trees, which reduces oxygen. Also, there it makes it reduces places for animals to live.
500
What is the difference between an adaptation and a trait?
What is an adaptation is a characteristic that improves an individual's ability to survive and reproduce in a particular environment. A trait is genetically determined characteristic.
500
If two species have similar DNA, what would you infer about their ancestry? Explain.
What is they are related because they have similar genetics.
500
What are the four parts of natural selection?
What is overproduction, inherited variation, struggle to survive, and successful reproduction.
500
How can new species form?
What is when species become separated, adapt, and reproduce.
500
Explain how human population growth is related to pollution problems.
What is each person causes pollution. As there are more people, there is more pollution.
