Question

Brachiation is a form of locomotion: a. where movement occurs through the use of the arms and a specially adapted tail, which can grasp tree branches. b. where movement occurs through arm-over-arm swinging. c. where the body is oriented vertically and movement occurs by leaping from tree to tree. d. where all four limbs are used to move through the trees.

Answer 1

b. where movement occurs through arm-over-arm swinging.

Step-by-step explanation:

Brachiation is a form of locomotion observed in some species of animal that are adapted to arboreal (tree living) life.

This type of locomotion involves the swinging of arms and the suspension of the body to move from trees to trees.

Animals that exhibit brachiation usually have modified body structure with long forelimbs/hook-like fingers and a highly mobile shoulder joints. Examples of such animals include gibbons and siamangs.

The correct option is b.
