Answer 1

Answer:

1. The skeleton provides a framework for organs and soft tissue attachment.
2. Blood is formed in the red bone marrow.
3. Calcium is released and deposited in the bones and blood to maintain (calcium) homeostasis.
4. Minerals (calcium and phosphorus) are stored in the bones.
5. When muscles contract/relax, the bones attached to them move.

Explanation:

• The skeleton is made up of bones that attaches muscle to the organs. Together, it allows the movement of body for a desired task, e.g. walking, exercising, eating, etc.
• Organisms usually have two types of bone marrows, i.e. red and yellow. Red bone marrow is typical for the production of red blood cells (blood) along with platelets and white blood cell formation. In the yellow bone marrow, however, only white blood cells are formed.
• Calcium release in the blood is controlled by parathyroid hormone. Its optimal release is important for calcium homeostasis of the living organism both for bone formation and other biochemical processes.
• Minerals mainly calcium and phosphorus are stored in the bones. In the animal's body, 99% calcium and 85% of phosphorus are stored in the bones.
• The contraction and relaxing of muscle are crucial for the movement of animal's body. For that, two types of muscle fibers namely actin and myosin work together. Actin slides on myosin which is governed by nerve impulses and results in contraction. The relaxing of muscle is an opposite process in which muscle fibers restore to their original positions.
