State the functions of the skeletal system, including the number and the major bones in the human skeleton.

Answers

The skeletal system serves several important functions in the human body. These functions include:

1. Support: The skeleton provides the structural framework for the body, giving support and shape to the organism.

2. Protection: The skeletal system protects vital organs such as the brain, spinal cord, heart, and lungs. For example, the skull protects the brain, the ribcage protects the heart and lungs, and the vertebrae protect the spinal cord.

3. Movement: Bones act as levers for muscles, enabling body movement. The skeletal system works in conjunction with the muscular system to facilitate motion.

4. Mineral storage: Bones store essential minerals, such as calcium and phosphorus, which are necessary for various body functions.

5. Blood cell production: Red and white blood cells, as well as platelets, are produced in the bone marrow, which is found in some bones.

6. Energy storage: Yellow bone marrow, found in the medullary cavity of long bones, stores energy in the form of fat.

The human skeleton consists of 206 bones in adults. Some of the major bones include:

1. Skull: Comprised of the cranium and facial bones, it protects the brain and supports the structures of the head.

2. Spine (vertebral column): Consists of 33 vertebrae, which protect the spinal cord and support the upper body.

3. Ribcage: Includes 12 pairs of ribs, the sternum, and the thoracic vertebrae, which protect the heart and lungs.

4. Humerus: The long bone in the upper arm, connecting the shoulder to the elbow.

5. Radius and Ulna: The two bones in the forearm, connecting the elbow to the wrist.

6. Femur: The long bone in the thigh, connecting the hip to the knee, and is the longest bone in the body.

7. Tibia and Fibula: The two bones in the lower leg, connecting the knee to the ankle.

8. Pelvis: A basin-shaped structure that supports the spine and organs of the lower abdomen, and connects the spine to the lower limbs.

These are just a few examples of the major bones in the human skeleton.

Answer:

Explanation:skeletal system functions are diffrent of types . In addition to defining our shape and traits as humans, it:

enables movement: Your skeleton helps you stand and move by supporting your weight. Your bodily components are movable thanks to the cooperation of joints, connective tissue, and muscles.

Bone marrow, which makes blood cells, is found in bones. The bone marrow makes RBC AND WBC

supports and shields organs: Your ribs shield your heart and lungs, your backbone shields your spine, and your skull shields your brain.

Mineral storage: Your bones are where your body stores minerals like calcium and vitamin D.

Explanation:

Existing rocks are buried and forced toward the mantle, increasing heat and pressure. This is the first step in the formation of metamorphic rocks.

(PLEASE HELPPPP 90 POINTS!!)

Which best describes the next step in the formation of metamorphic rocks?

Buried rocks melt deep within the mantle.
Lava melts underlying rocks, which crystallize into new minerals.
Rocks that were buried are exposed at Earth’s surface, where they are weathered and eroded.
Magma pockets rise, which increases heat, and minerals change due to temperature and pressure.

Answers


The correct answer is B. When buried rocks are forced toward the mantle, they undergo extreme heating and pressure, which can cause them to melt. This molten rock is known as magma, which then crystallizes as new minerals as the magma cools and solidifies. This process is known as metamorphosis and is the second step in the formation of metamorphic rocks.

Buried rocks melt deep within the mantle.

matter 1. What do you think it means for a solid to have a definite shape? (hint: a gas/liquid does not have a definite shape). _________________________________________________________________________________________ 2. How can solids be transformed into other states of matter? Give an example. _______________________________________________________________________________

Answers

Answer:

1.) Particles in a solid have fixed locations in a volume that does not change. • Solids have a definite volume and shape because particles in a solid vibrate around fixed locations.

2.) It's a process called sublimation. The easiest example of sublimation might be dry ice. Dry ice is solid carbon dioxide. When you leave dry ice out in a room, it just turns into a gas.
