Answer 11

Size, number of cells, and organization

Question 12

What can give us an idea about an animals behavioural complexity

Answer 12

Their brain size

Question 13

Answer 13

It is the ratio of actual brain size to the expected brain size (according to the body size). The average animal has an EQ of one.
