In 2010, scientists excavated a skull fossil that provides evidence of a newly discovered species of big cat. Based on the evidence, scientists hypothesize that big cats branched off from smaller wild cats about 6 million years ago. Which of these resources did the scientists most likely rely on to form their hypothesis?

The fossil record and DNA comparisons of big cats and small cats

A food web showing feeding relationships of organisms where the fossil skull was found

Population and migration data for small wild cats living in the ecosystem where the skull was found

The historical record of interactions between different species of big cats

This question has two parts. First, answer Part A. Then, answer Part B. The table shows the number of differences in the amino acid sequence of a protein called cytochrome C in three species of fungi. Part A Based on the data, which two species of fungi are MOST CLOSELY related? Candida albicans and Saccharomyces cerevisiae Part B Which evidence BEST supports the answer to Part A? The two species have high molecular homology.

Candida albicans and Saccharomyces cerevisiae

The two species have high molecular homology.

Neurospora crassa and Candida albicans

Saccharomyces cerevisiae and Neurospora crassa

The two species have anatomical similarities.

The two species are able to reproduce.

The two species are both fungi.

After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae , a giant scorpion species that lived 255 million to 460 million years ago, was 2.5 meters long. Which of the following conclusions is supported by this information?

Scorpions have changed as a result of natural selection.

Scorpions living today have increased their numbers since they first appeared.

Scorpions in the fossil record are smaller than their descendants are.

Scorpions do not appear in their original state in the fossil record.

Male guppies found in areas without predators are more colorful than the ones found in locations with large predator populations. A population of adult guppies originating from an area with a large number of predators is transferred to a nearby area with few predators. Which of these is most likely to happen over a few generations?

There will be an increase in the number of colorful guppies.

The mortality rate of the guppies will increase.

Offspring will stop competing for resources.

There will be an increase in mutations in the offspring.

The graphs show changes in allele frequencies in a population at three points in time as a drought becomes more severe. Which statement best describes how natural selection affects alleles?

Natural selection affects allele frequencies differently depending on how helpful an allele is to an organism's fitness for its environment.

Natural selection always affects how the same allele influences an organism's reproductive success.

Natural selection affects alleles randomly, leading to small changes in allele frequencies.

Natural selection affects allele frequencies in individuals, not in populations.

Blue flying fish live in the upper layers of the ocean. Blue flying fish have enlarged pectoral fins that enable them to glide for 400 meters above the ocean surface and appear to fly. Which statement best describes how natural selection led to enlarged pectoral fins in blue flying fish?

Fish with enlarged pectoral fins were able to glide out of the ocean to escape predators, increasing their fitness.

Fish were able to glide out of the ocean and into other bodies of water to mate with other species.

Fish were able to live both on land and in the water as a result of their larger pectoral fins.

Fish changed their DNA to express enlarged pectoral fins, changing the allele frequency of the 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 the environment than brown beetles are.

Brown beetles undergo a greater number of unfavorable mutations than green beetles do.

Green beetles have a greater gene frequency among their population than brown beetles have.

Brown beetles have a shorter life cycle than green beetles have.

A large population of rock pocket mice with various fur colors lives in a designated area. Soon after a volcanic eruption, the number of mice with dark-colored fur in the population increased. Which statement BEST describes the reason for the change in fur color?

The fitness of mice with dark-colored fur increased, so they became more abundant.

Mutations for dark-colored fur were passed down within the somatic cells, resulting in more mice with dark-colored fur.

Mice with light-colored fur selected mutations that allowed their fur to become darker.

Mice with light-colored fur began feeding in the daytime to stimulate the release of a pigment for dark-colored fur.

Two populations of mice living in the same forest are separated by a large water-filled ditch. After a rainstorm, flooding brings several mice from one population to the other population. When the mice from the first population reproduce with members of the second population, which of the following will likely occur?

The offspring in the second population will have greater genetic variety.

All the offspring will die as a result of reproductive mutations.

The offspring will be forced to leave the second population.

The offspring will be genetically identical to their parent from the first population.

The gray squirrel, Easter fox squirrel, and red squirrel are all different species of squirrels. Why is having a scientific name for each species of an organism important?

To standardize the naming and organization of organisms to avoid confusion

To prevent existing named organisms from having their names changed as they become extinct

To keep the classification system from being altered as new organisms are discovered

To allow organisms to be placed in many classification levels at the same time

Many tree frog populations are threatened due to habitat loss. In an effort to promote conservation, tree frogs may be bred in captivity. A zoo acquired male and female tree frogs from two different populations. In the zoo, the tree frogs were able to successfully mate within their own population, but breeding attempts between the two populations were unsuccessful. Based on this information, which statement correctly describes the relationship between the two populations of tree frogs?

They are in the same genus but different species.

They are in the same species but different kingdoms.

They are in the same class but different phyla.

They are in the same family but different orders.
