Questions: 28 | Attempts: 934 | Last updated: Feb 10, 2023

Sample Question 1
The "biological species concept" offers us a practical way to distinguish species of organisms and to assign individuals to one taxon or another. In order to catalog individuals as being members of one species or antoehr using this concept focuses on

Morphological differences distinguishing the species

Differences in the geographic distribution of the species

The ability of individuals to successfully breed with each other

Sample Question 2
The animals and plants found in modern India differ greatly from species in nearby southeast Asia. Your authros offer one example of that in chapter 24 involving frogs. A likely explanation is that

The species in the two areas have become separated by convergent evolution

The climates of the two regions are similar

India is in the process of separating from the rest of Asia

Life in India was wiped out by ancient large-scale volcanic eruptions

India was a separate continent until about 55 million years ago.

Sample Question 3
The theory that a meteor impact played a role in the mass extinction of dinosaurs is supported by all of the following EXCEPT which one?

Discovery of a crater dating to 65 million years ago

Shock crystal distributions

A layer of the rare earth element iridium in deposits dating to the time of that mass extinction

Caves near Lascaux in France have sketches, engravings and paintings depicting events around the time of the event

Results of computer modeling of volcanic and nuclear incidents
