Explanation:

To answer these questions, you need to watch the video at the provided URL ("The Skeletal System") and then extract the relevant information:

Question 1: What are the two types of completed skeletons called?

From the video (and the hint in the left panel), the two types of completed skeletons are exoskeletons and endoskeletons.

Question 2: What are some pros and cons of each?

• Exoskeleton:
• Pros: Provides strong external protection (e.g., against predators), supports the body, and can prevent water loss (in arthropods).
• Cons: Limits growth (must be shed/molted), can be heavy (restricting movement in larger organisms), and requires energy to molt.
• Endoskeleton:
• Pros: Grows with the organism, allows for larger body size, provides flexible internal support, and protects internal organs (e.g., skull, ribcage).
• Cons: Less external protection (relies on skin/muscles for defense), and injuries to the skeleton (e.g., fractures) can be severe.

Question 3: What are the five main functions of the skeletal system?

From the left panel (and the video), the five main functions are:

1. Support: Holds the body upright and gives it structure.
2. Protection: Shields internal organs (e.g., ribcage protects the heart/lungs, skull protects the brain).
3. Movement: Works with muscles to enable motion (bones act as levers, joints as fulcrums).
4. Blood cell production: Occurs in bone marrow (red marrow makes red/white blood cells, platelets).
5. Mineral storage: Stores calcium and phosphorus (released into the bloodstream as needed).

Question 4: What two systems work together to allow for movement?

The skeletal system (bones, joints) and the muscular system (muscles, tendons) work together for movement.

Question 5: How do they work together?

• Muscles attach to bones via tendons. When a muscle contracts, it pulls on the bone it is attached to.
• Bones act as levers, and joints act as fulcrums, allowing the muscle’s force to create movement (e.g., bending an arm: the biceps contracts, pulling the forearm bone up at the elbow joint).
• The skeletal system provides the structure and leverage, while the muscular system provides the force to move the bones.

If you need further clarification, rewatch the video or reference a textbook on human/anatomy/biology.
