Mutations are important because they bring about

genetic variation needed for a population to evolve

death of the organism in which they develop

benefits for the individual, not for the population

Hardey-Weinberg equilibrium within a population

The table shows the survival rate of two types of beetles in the same environment over a period of three years. Which statement about the beetles in this environment is best supported by the data?

Green beetles are more fit for their environment than brown beetles

Brown beetles have a shorter life cycle than green beetles have

brown beetles are undergo more unfavorable mutations than green beetles

Some animals are able to see in ultraviolet (UV) light. Bees for instance can see Green and Blue and UV, but no Red, but butterflies and birds can see Red, Green, Blue and UV. Why would a plant need these special ultra violet markings?

Attract insects to help it pollinate

to show insects they are poisonous

Dogs are closely related to wolves. To prove this, what type of testing or experiment would a scientist most likely carry out?

examine their social habits and record similarities

feed them similar foods and see if they have similar diets

determine whether a female dog will care for a wolf pup

The Asian shore crab invaded parts of the eastern coast of the United States about 15 years ago. The Asian shore crab preys on blue mussels. In the time since the Asian shore crab arrived, the average shell thickness of the blue mussel population has increased. Which of the following is the most likely reason that this increase in shell thickness has occurred?

Blue mussels with thick shells survive and reproduce more successfully than mussels without thick shells.

Blue mussels with thick shells attract more crabs that mussels without thick shells.

Blue mussels with thick shells grow in larger colonies than mussels without thick shells.

Blue mussels with thick shells catch more food per day than mussels without thick shells.

In recent years "SuperBugs" (bacteria that aren't effected by antibiotics) are becoming more and more common. How could natural selection explain this?

Superbugs survive antibiotics and reproduce

Antibiotics cause bacteria to become superbugs

We have always had the same amount of superbugs; modern media just discusses them more.

There is no reliable data on the origin of super bugs.

Why would a population with a large amount of genetic variation be more likely to survive a severe climate change in its environment?

Some individuals will posses traits better suited to the new climate and be more likely to pass them on

Individuals will only create offspring well-suited to the climate change

The individuals would produce more offspring

Individuals better suited to the new climate will help less-suited individuals survive

Crossing over is important because....

It allows for more genetic diversity of gametes.

It prevents mutations from entering the gametes.

It allows for even distribution of chromosomes in the gametes.

It allows for genetic uniformity of gametes.

Since the 1800s humans have stopped burning coal, and the trees have returned to their original color. Which moth will be more successful in this environment?

Both will be equally successful

Why is the mouse population changing over time?

The hawks eat more light mice than dark mice because they can see the light mice more easily

The light mice can reproduce more successfully than the dark mice

The hawks eat more dark mice than light mice because the dark mice taste better

The hawks eat more dark mice than light mice because they can see the dark mice more easily

Darwin determined that the 13 species of finch found in the Galapagos Islands

probably all came from the same ancestral species

had all adapted to the same food source

were identical to species 600 miles away

were the result of careful breeding by humans

What is the correct explanation for what is happening in this graph?

There are a lot of small and large beaks, but not average-sized ones

There are a lot of average-sized beaks

There are a lot of small beaks only

Why are advantageous traits more likely to be passed onto offspring?

Because they are more likely to survive and reproduce.

Because they come from dominant alleles.

Because they come from recessive alleles.

Because the trait is an acquired phenotype.

A fossil of an extinct dinosaur is found and the anatomy of the fossil shows similarities to that of a bird. What could this mean?

This is purely by chance and isn't significant

The extinct dinosaur and modern bird share a common ancestor

All dinosaurs evolved into birds and that's why there aren't any dinosaurs alive today

Dinosaurs choose to fly, and evolved into birds to escape predation and capture food

What is natural selection?

Sharp reduction in population size due to an environmental disaster, often results in loss of variation

When individuals survive and reproduce at a higher rate than others in the same population due to some environmental pressure
