From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term  in the rock cycle is melting

Hence we can conclude that from the diagram of the rock cycle the missing part is Melting.

The inference one can draw based on these observations is that the insect goes through incomplete metamorphosis because it does not change drastically as it becomes an adult, which is the second option. Hence, the second option is correct.

Incomplete metamorphosis involves three life stages: egg, nymph, and adult. Insects that undergo incomplete metamorphosis generally resemble miniature versions of the adults as they grow and molt their exoskeletons several times before reaching their final adult form. The changes observed in the insect, such as molting and slight changes in appearance, are consistent with the characteristics of incomplete metamorphosis. Furthermore, the presence of colorful wings and thin legs in the adult insect indicates that it has reached its final stage of development without undergoing a drastic transformation, which is a key feature of incomplete metamorphosis. Hence, the second option is correct.

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.

The sac-like structure of the alveoli increases their surface area. In addition, the alveoli are made of thin-walled parenchymal cells. These features allow gases to easily diffuse across the cells. so the

Alveoli has thin walls which are surrounded by blood vessels, and they have maximized are for gas exchange. Thus, option A, B, and D are correct.

These are basic respiratory units, which are balloon like structure present in the lungs, where exchange of gases takes place. A pair of human lungs can contain approximately 480 million alveoli, which produces about, 50 to 75 square meters surface are.

Alveoli are made of thin walls, and they are covered by a rich blood supply through capillaries, this supplies a diffusion gradient for oxygen to move into the blood and carbon dioxide to move into the lungs.

Therefore, the larger surface area, presence of thin wall, which is only one cell thick,  and rich blood supply due to presence of blood vessels enable them to exchange gases efficiently.
