Carson wants to determine if males or females have faster reaction times. He tested eight males from the varsity basketball team. He randomly selected eight females from his algebra class to test. He had each test subject separate his or her index finger and thumb exactly one inch apart. He then dropped a ruler between the index finger and thumb and measured the distance on the ruler. The quicker the reaction time, the smaller the measurement on the ruler. His results are recorded in the table below. From his data, Carson concluded that males have faster reaction times than females. His teacher, however, says his data is skewed. What should Carson have changed about his experiment to make his conclusion more scientifically valid?

He should have randomly picked males from his class instead of using basketball players

He should have included teachers in his study instead of using only students

He should have tested fewer males and females

He should have increased the width between the finger and thumb by two inches instead of one inch

Two normal parents having 46 chromosomes each have a child with 47 chromosomes. As a result, the child is born with Down's syndrome. Which of the following is the MOST likely cause of this disorder?

Nondisjunction occurred during the formation of the mother's egg cell

A frameshift mutation occurred during meiosis

A point mutation occurred in one of the chromosomes as the child developed in the womb

A gene duplication occurred in one of the chromosomes as the child developed in the womb.

A few birds from a mainland population migrate to a newly formed volcanic island. Why are the island birds more likely to undergo speciation than the mainland birds?

Natural selection will have a more significant impact on the island birds' smaller gene pool

The mainland birds will continue to interbreed with the island birds to create new species

The smaller island population will produce more offspring, so speciation is more probable

The smaller island population will have greater diversity due to a larger gene pool

Why is ATP important?

It stores energy needed for cells to undergo life processes

It is a major component of carbohydrates

It speeds up reaction times so that metabolic processes are possible

It stores the genetic material needed for cells to make proteins

Tall pea plants are dominant (T) over short pea plants (t). If a homozygous tall plant is crossed with a homozygous short plant, what would be the expected phenotypes of the offspring?

75% tall plants and 25% short plants

Which of the following is true when using the high-power objective on a light microscope?

Which of these would be LEAST likely to happen if someone released an exotic species of wild animal into the environment?

The animal would compete with native animals for food.

Although birds and butterflies both have wings, the wings are very different structurally. What conclusion would you draw from this information?

Birds and butterflies do not share a close common ancestor

Birds and butterflies share a close common ancestor

Zebra mussels are a non-native species of mollusk that have been introduced into United States waterways. They are filter feeders that eat plankton. The golden shiner, a common minnow, also eats plankton. In Vicksburg, Mississippi, zebra mussels are newly discovered in a small community pond. At the initial discovery and for the next three years, scientists gather data on plankton concentration, zebra mussel populations, and golden shiner populations in the pond. The table below summarizes their data. If the zebra mussel population continues to grow, which of the following predictions might be made for the year 2011?

The plankton and golden shiner populations will continue to decrease

The plankton population will increase, and the golden shiners population will remain the same

Golden shiners will begin to eat zebra mussels in addition to plankton

The plankton and the golden shiner populations will begin to increase

If the amount of fungi and bacteria in a woodland ecosystem decreases, which of the following is MOST likely to occur?
