Five species of frogs that live in separate habitats within 5 non-overlapping ranges along the Mississippi River share a common ancestor. Which process is most likely responsible for the formation of these five distinct species?

• Physiological isolation

• Geographic isolation

A student wanted to compare the transpiration rates of two different plant species at varying level of humidity. The results are recorded in the table shown.

Each plant group was given the same amount of water and light throughout the investigation. Which procedure should have been performed to prevent error in this investigation'?

• One type of plant should have been tested

• Fewer plants should have been included in each group

• The percentage of humidity should have been kept constant.

• Both groups should have been tested in the same soil type at each humidity level

Change in species is described as a process that usually occurs over long period of time. Yet, even though antibiotics have only been widely used for fifty years, scientist recognize that overuse of antibiotics has led to antibiotic-resistant strains of bacteria. The reason this can occur in a relatively short span of time is that

• bacteria are very small

• bacteria reproduce rapidly

• there are many different types of bacteria

• travelers carry bacteria around the world

• YY, yy only

• YY, Yy, yy onlu

• Yy only

One parent is homozygous recessive for a certain trait. The other parent is homozygous dominant. What is the percent chance that an offspring from this cross would be heterozygous?

• 25%

• 50%

• 75%

• 100%

A group of ponies lives in the Chincoteague National Wildlife Reserve in Virginia. The development of longer legs over time would be selected for if

• it increased the survival rate of the long-legged ponies

• It decreased the rate of reproduction of the long-legged ponies

• It prohibited the long-legged ponies from using available food sources

• It made the long-legged ponies run more slowly

According to the diagram, the result of spermatogenesis within males are four sperm cells, each with

• strands of DNA that resulted from crossing over
