How does natural selection lead to evolution

a species can gradually change into new species

What is a nonnative species

A species that does not normally live in an area

Competitive exclusion is most likely to occur between two

closely related species occupying the same niche.

What did Malthus think would limit the population size

Food supply

What is the fitness of an organism

The ability to survive and reproduce

What is the best reason that bright-colored feathers could be an adaptation for a bird living in a temperate forest

It could make the bird attract mates

What best summarizes the peppered moths in England after the Industrial Revolution

When can exponential growth happen

when there is no competition

When there are unlimited resources- Apex Exponential growth can happen anytime when the rate of the growth is increasing along with an increase in growth.

What is a reproductive strategy

The method an organism uses to produce offspring

the way that a species creates offspring

What causes the phenotype frequency in a population to change after each generation

Gene mutation causes the phenotype frequency in a population to change after each generation.

Which would be an adaptation in a very cold place but not the rain forest

fur that blends in with snow

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.

You mama

The allele frequency does not change.

What question did charles darwin attempt to answer-

Charles Darwin tried to answer why do different organisms live in different places.

What does p2 represent in the Hardy-Weinberg equation

The frequency of the homozygous dominant genotype.

How do peppered moths after the industrial revolution show the process of the natural selection

the moths with the highest fitness were selected for. (apex)

Which is true about adaptations

They are passed along to offspring.

Which is an adaptation

A bird has fathers that help it fly father. (Apex)
