• A. 1, 2
• B. 1
• C. 1, 3
• D. 2

Answer 1

Answer:

A. 1, 2

• The biological species concept defines a species as a group of organisms that can naturally interbreed and produce fertile offspring.

• This definition emphasizes reproductive isolation, meaning that members of different species are generally unable to produce viable, fertile offspring.

• However, this concept has limitations, particularly for asexual organisms or those that can hybridize in nature.

• Other species concepts, such as phylogenetic or morphological concepts, also exist to classify life forms.
