Rotator cuff
The rotator cuff is a group of muscles that perform a variety of tasks such as flexion, abduction, internal rotation and external rotation. The muscles in this group are essential to all movement of the shoulder, making them very essential for upper body mobility. Namely, the muscles of the rotator cuff are supraspinatus, infraspinatus, teres minor and subscapularis.
The correct answer is: marsupials.
Marsupials are actually defined by their ability to hold the young in the pouches, where they can be well protected. Some examples are Kangaroos and Koalas.
Other answers are wrong: for example, gymnosperms are plants, not animals.
The law of conservation of mass states that the mass will stay constant given a chemical reaction because no atoms were created or destroyed. This being said, an example can include water evaporating in a clear bottle outside on a hot day ( the mass of the bottle will stay the same, but the liquid water evaporated into gaseous water).
Answer:
Elbow
Explanation:
Muscle works in pairs and groups e.g biceps flexes the elbow and triceps extend it and it is called antagonistic muscle action.
The working muscle is called the primer mover or agonist. The relaxing muscle by another muscle is called synergists.
When muscles cause a limb to move through the joint range of motion,it could be synergists or antagonists.
