A trait that an organism expresses during its lifetime will only cause its species to become better adapted if the trait—

A. Is caused by the genetic code that is present in the gametes of the organism

A. Results from isolation of the organism from the rest of the population

A. Causes a change in the environment surrounding the organism

A. Decreases the number of genes in the body cells of the organism

A graph regarding the effect of agricultural bioengineering on insect pests is shown below How has natural selection affected species of insect pests?

A. Natural selection has rapidly increased the number of species that are resistant to pesticides

A. Natural selection has not affected the number of species that are resistant to pesticides

A. Natural selection has only affected the number of species that are resistant to pesticides

The green frog (Lithobates clamitans clamitans) is found in many parts of the United States. The table contains some information about this frog. Why does the ability to lay 1,000 to 5,000 eggs increase the fitness of the species L. clamitans clamitans?

A. It increases the probability that some offspring will survive long enough to reproduce.

It increases the chance of the recombination of alleles, leading to genetic drift in the population.

A. It increases opportunities for offspring to compete for limited resources.

Certain insects resemble (look like) the bark of the trees on which they live. Which statement provides the best explanation for this resemblance ? (Peppered Moths)

Natural selection played a role in this protective coloration

The trees caused mutations in the insects

The insect camouflage so they developed this coloration

The structural similarity shown in the organisms pictured here suggests that –

the organisms have common ancestors.

similar bones are the same size in all animals.

some bones in the skeleton have immovable joints.

only quadrupeds need the humerus bone.

Which of the following can be concluded from the evolutionary tree provided?

The differences are greatest between species B and C.

All three species became more complex over time.

There is evidence of large gaps in the fossil record.

The common ancestor was most similar to species C.

One difference between plants and animals is that plants are

autotrophs and animals are heterotrophs.

prokaryotic and animals are eukaryotic.

eukaryotic and animals are prokaryotic.

heterotrophs and animals are autotrophs.

The diagram shows light- and dark-colored beetles that live on a tree. Which result is most likely to occur to the beetle population due to predation over time?

The number of light-colored beetles in the population will increase.

There will be more dark-colored beetles than light-colored beetles.

The number of light-colored beetles will decrease.

The dark-colored beetles will move to a different type of tree.

The image shows part of the humerus bone in different genera of primates. Which statement is best supported by the observable structures of the different humerus bones?

The primates shared a common ancestor.

The primates lived in similar environments

The primates interbreed with similar organisms in a population.

The primates had diets that consisted of similar types of foods.

Which of the following would be an example of what evolutionists call a vestigial structure?

The lack in size of the ostrich wing.

The forelimb bones of a gorilla and a horse.

The wings of a bat and the wings of a bird.

Imagine Aiden, Sawyer, and Christian are studying about population dynamics. They came across a term 'bottleneck effect'. Can you help them understand what it is?

It's when a population shrinks suddenly due to an outside cause

It's when a population grows rapidly due to an outside cause

It's when a population stays the same size due to an outside cause

It's when a population migrates to a new location due to an outside cause

What does the "bottleneck effect" refer to in genetic terms?

A genetic scenario where a population's size decreases suddenly, usually due to an external event, leading to reduced genetic variation

A method of tracking genetic changes over time

A situation where a population's size increases suddenly

A process where new genes are introduced into a population

How did the sea otter population change by 1911 due to human activities?

The population decreased to about 2,000 otters

The population increased to over 100,000

The population remained stable with no significant changes

The population expanded into new oceanic territories

What is a genetic bottleneck?

A process where a large population becomes very small, leading to a decrease in genetic variation.

An increase in population size after a natural disaster.

A method by which animals adapt to new environments.

A technique used by scientists to increase genetic diversity.

What happens to the variety of genes in a species after a bottleneck event?

It varies depending on the species.
