Millions of years ago, four aquatic organisms died, and their remains came to rest on Earth’s surface beneath the water. Which of the organisms could most likely be studied today using fossils?
1
2
3
4
Who was the first person to base a system of classification on organisms having similar structures?
Albert Einstein
Carl Linnaeus
Aristotle
Charles Darwin
Which of these characteristics best helps scientists classify organisms?
gender
size
structure

Scientists studied the taxonomic relationship between two lizard species living on the sides of a canyon. One species had long toes and one had short toes, but they were alike in most other ways. The table shows what the scientists found. What is the most likely reason for these findings?
Short-toed lizards evolved from long-toed lizards on the shady side of the canyon.
Short-toed lizards evolved from long-toed lizards on the sunny side of the canyon.
Long-toed lizards evolved from short-toed lizards on the shady side of the canyon.
Long-toed lizards evolved from short-toed lizards on the sunny side of the canyon.
Organisms are classified into three domains:
1. Archaea
2. Bacteria
3. Eukarya
Organisms that live in extremely hot or acidic environments belong to...
1 only
2 only
1 and 2 only
1, 2, and 3
Scientists dug through three layers of rock and found many rabbit fossils. The fossils were complete enough to determine the length of the rabbits’ hind feet. Consider the data in the table. Which conclusion is best supported by the data?
Over time, rabbits that had shorter feet lived longer than rabbits that had longer feet.
Over time, rabbits that had longer feet had more offspring than rabbits that had shorter feet.
Over time, rabbits that had shorter feet had more offspring than rabbits that had longer feet.
Over time, rabbits that had longer feet lived longer than rabbits that had shorter feet.
Imprints of the shells of ocean clams are often found in the rocks of the Appalachian Mountains. What do these imprint fossils most likely indicate?
Ocean clams evolved from mountain river clams.
These mountains were once under the ocean.
Mountain river clams evolved from ocean clams.
These mountains once had a more rainy climate.
Wild blackberries reproduce asexually by sprouting new roots when stems touch the ground. They also reproduce sexually through their flowers. What is the advantage of the blackberry plant being able to reproduce sexually and asexually?
It produces blackberries that have more flavor.
It allows blackberry plants to adapt to new conditions.
It produces flowers that attract insects.
It allows the plants to grow taller.
Scientists estimate that whaling activity in the 19th and early 20th centuries had reduced the number of adult female southern right whales (Eubalaena australis) to as few as sixty individuals by 1920. This reduction resulted in a genetic bottleneck for the species. Treaties to stop whaling have substantially increased the number of southern right whales. Despite this increase, the bottleneck still threatens the future of the species. Which ability of the species is most severely diminished by the bottleneck?
maintaining a healthy social structure
remaining genetically stable
responding to environmental changes
acquiring random mutations
A paleontologist found a fossil of an organism that looks like modern-day ferns. Which would most likely assist the paleontologist in proving that the two organisms are related?
comparing the structures of the fossil to that of modern-day ferns.
mapping the location of where the fossil grew against where modern-day
ferns grow.
recording how the tectonic plates have moved since the fossil was
created.
analyzing the composition of the rock in which the fossil was
discovered.
