How does natural selection lead to evolution

a species can gradually change into new species

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 is the name for the process that causes a species to evolve

A) natural selection ( apex (

What idea did Malthus introduce

Mathus felt that population is limited by food supply so we need to limit population growth or starve.

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)

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

allele frequency change Apex :)

What is the most likely reason that a long beak could be an adaptation for a bird living in a temperate forest

The beak could assist the bird with cracking open nuts,or attacking competitors.

What best describes the usefulness of a simulation as an experimental tool

it can help predict the outcome of an event

What is a reproductive strategy

The method an organism uses to produce offspring

the way that a species creates offspring

In what way do adaptations help the survival of a species

It increases the biodiversity of the species.

Why would natural selection not occur when a small number of finches live in a protected bird area and are given as much food as they need and plenty of space

There are enough resources for the birds.

The birds do not compete for resources.

The population has not reached carrying capacity.

What rainforest does the desert have

There is no desert with a rainforest.

What is true of adaptations

D, organisms are born with them. Apex

Why are certain traits adaptions in one environment but not the other

Different environments have different abiotic conditions

How are finches in the Galapagos island a good example adaptation

Each species has a special break adaption. - APEX

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)

How do adaptions affects a species

They make the species more likely to survive. - APEX

What animal is a behavioral adaptaion

An animal can not BE a behavioural adaption, it can only DISPLAY a behavioural adaption.

Which best summarizes the concept of natural selection

The fittest organisms survive and reproduce

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)
