Q

What is the purpose of the binomial naming system?

A

Enables scientists to communicate about organisms in a standard way which helps to avoid the confusion of common names (universal)

Q

How does courtship behaviour allow members of the same species to recognise each other?

A

-Specific to each species
-Only members of the same species will do and respond to that behaviour

Q

What does courtship behaviour prevent?

A

-Interbreeding (makes reproductions more successful)

17
Q

How is courtship behaviour used to classify organisms?

A

-The more closely related species are the more similar their courtship behaviour will be as it is specific

18
Q

How can organisms be classified by immunological comparisons?

A

-Similar proteins will bind to similar antibodies

19
Q

How can classification by made by using genome sequencing?

A

-An entire base sequence of an organism’s DNA can be determined
-Base sequences can be compared between organisms to see how closely related they are
