Accepted Answer

The answer of The presence of a tailbone in humans...

Question 2

Special creation is NOT considered a scientific hypothesis because no one has ever tested it using scientific means.

Accepted Answer

A) True 
 B)False

Question 3

What should you look for when considering whether structures from two kinds of organisms are homologous?

Accepted Answer

A)  The structures should have identical functions in both organisms. 
B)  The structures should be in different positions on the bodies of the two organisms. 
C)  The structures should not appear in any close relatives of the organisms. 
D)  The structures should have similar anatomy in the two organisms. 
A)  The structures should have identical functions in both organisms. 
B)  The structures should be in different positions on the bodies of the two organisms. 
C)  The structures should not appear in any close relatives of the organisms. 
D)  The structures should have similar anatomy in the two organisms.

Question 4

When comparing different families of animals, you would expect gene-coding for proteins that perform basic cell functions to show much higher homology than gene-coding for proteins involved in coordinating organ systems.

Accepted Answer

A) True 
 B)False

Question 5

The standard classification system used by biologists today groups and classifies organisms on the basis of similar physical traits. This system was first developed by Carl Linnaeus. At the time of his work, there were other methods for grouping organisms that were based on similar habitats, similar diets, or similar behaviors. Why is Linnaeus's system the most useful one to biologists today?

Accepted Answer

A)  Linnaeus's system is the simplest; the others are too complicated. 
B)  Classifying on the basis of shared traits points out the underlying evolutionary relationships among organisms. 
C)  Linnaeus's system included all organisms found on Earth. 
D)  Linnaeus's system relies on Latin names that make the most sense to biologists.

Question 6

Which of the following levels would contain members that are the most similar?

Accepted Answer

A)  class 
B)  genus 
C)  kingdom 
D)  order 
A)  class 
B)  genus 
C)  kingdom 
D)  order

Question 7

DNA evidence has strongly supported the original groupings proposed by Carl Linnaeus to show relationships between organisms.

Accepted Answer

A) True 
 B)False

Question 8

The DNA of cats and dogs is much more similar than the DNA of cats and hamsters. Why is that?

Accepted Answer

A)  Cats and dogs have lived together with humans for a longer period of time, so they have grown more similar. 
B)  Cats and dogs have a common ancestor that is more recent than the common ancestor of cats and hamsters. 
C)  The ancestors of cats and the ancestors of dogs evolved in similar environments. 
D)  Cats and dogs have fewer offspring during their lifetime than hamsters, so their DNA change less rapidly.

C)  The ancestors of cats and the ancestors of dogs evolved in similar environments. 
D)  Cats and dogs have fewer offspring during their lifetime than hamsters, so their DNA change less rapidly.

The term that describes distribution patterns of living things around the world is ________.

Accepted Answer

The answer of The term that describes distribution patterns of...

Question 10

What is it about macroevolution that people find controversial?

Accepted Answer

A)  the appearance of new traits in existing populations 
B)  the common descent of all organisms from one ancestral cell 
C)  the concept of species being subdivided into separate populations 
D)  the concept that genes can vary spontaneously
