an ape.

an orangutan.

Answer 1

1) the right answer is "colour vision". Because arboreal locomotion describes the movement of animals which are living on the trees .

3) binocular vision provides primates with "depth perception ". Most primates have binocular vision and forward-facing eyes. Which help in depth perception .

4) the right answer is "an orangutan" because the dental formula is 2.1.2.3 and have no tail. they have 2 incisors 1 canine 2 premolars and 3 molars . Apes also have 2.1.2.3 but most monkeys have tail for balencing in tree .

2) Race is a social construction.

Race is not biological , and genetical , it is a social construct. There is no gene or cluster of genes common to all black or all whites .
