Question

The smells and calls that animals use to communicate are systematic.
a. True
b. False

Answer 1

The correct answer is option a. "True". Something that is systematic must be performed according to a plan or a method. The smells and calls that most animals perform to communicate are systematic, because they follow a defined pattern. A clear example are the whales, which use particular noises to communicate and socialize.

Answer 2

True, I think. I'm pretty sure it would be because the animals aren't taught how to do so.
