Question 9

Question 15

Which of the following best explains why scientific names are written in Latin?

Accepted Answer

Latin is a 'dead' language and does not change, providing consistency.

Question 16

If two organisms share the same genus but have different species names, what does this indicate?

Accepted Answer

They are closely related but are different species.

Question 17

Which of the following is a benefit of using a classification system in biology?

Accepted Answer

It makes it easier to find and study organisms.

Question 18

Which of the following is an example of a taxon?

Accepted Answer

Species

Question 19

A scientist discovers a new organism that can mate with known wolves and produce fertile offspring. According to the biological species concept, how should this organism be classified?

Accepted Answer

As a member of the same species as the wolf

Question 20
