How does natural selection lead to evolution

a species can gradually change into new species

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

What did Malthus think would limit the population size

Food supply

Which best summarizes the peppered moths in England after the industrial revolution

The phenotype changed, which resulted in a black color adaptation.

How do peppered moths after the Industrial Revolution show the process of natural selection

The peppered moth had white bodies and wings, peppered with black. This coloration blended well into the original British countryside, hiding them from their predator the birds. Factories of the early industrial revolution covered everything with soot. Now the white stood out against the black surroundings making them easy targets for birds. Over time the white moths were wiped out. But, a few of them were darker in color, these survived and multiplied such that the white peppered moth was replaced buy the dark ones.

Black moths were selected for when the trees turned black.

the moths with the high fitness were selected for

The black moths were more fit for survival, so their phenotype frequency increased.

What question did Charles Darwin attempt to answer

Why do organisms in different places have different traits (apex)

How do adaptations affect a species

They make the species more genetically diverse

Which would be an adaptation in a very cold place but not in a rainforest

Fur that blends in with snow - APEX

What is a reproductive strategy

The method an organism uses to produce offspring

the way that a species creates offspring

Where is a place where a severe drought has occurred

A: Japan

How are finches in the Galapaagos Islands a good example of adaptation

Finches developed many different adaptations. For example, one type of finch had a short strong beak meant for cracking seeds, while another had a long narrow beak for gathering food from the inside of flowers, and cacti, therefore making each species more adapted to its specific environment and more able to gather food then they would on another island with a different main food source.

Which of these is one of the conditions for hardy-weinberg equilibrium

Mutations cannot occur - APEX

What is A trait has two alleles which are represented by p and q if p 0.89 what is q

0.56
