water moving up from the benthic zone

How does natural selection lead to evolution

a species can gradually change into new species

How are genes and proteins related

genes contain the code to make proteins

proteins are made from instructions in genes

What is an adaptation

a camel has humps to store water

a rabbit that has fur that blends in with snow

a trait that makes an organism more likely to reproduce

If all frogs died the raccoon population would most likely

increase

What is the fitness of an organism

The ability to survive and reproduce

Which of the following statements best describes the difference between a refracting telescope and a reflecting telescope

Please restate your question, or include your list of "following statements".

What must be true for natural selection to happen

There must be genetic variation in the population

The system must not be in hardy-weinberg equilibrium.

resources must be limited in the ecosystem

What did Malthus predict about the human population

It would grow too large and run out of food.

Why are certain traits adaptations in one ecosystem but not in another

An adaptation must fit the environment -Apex

How do adaptations affect a species

They make the species more genetically diverse

Which animal adaptation happened before the others

Development of a coelom

What is a reproductive strategy

The method an organism uses to produce offspring

the way that a species creates offspring

Which of the following was not part of Darwin's theory of natural selection
