Answer:
Osteoclasts are the type of cells which are responsible for the absorption of calcium from bones.
Explanation:
Osteoclasts is special type of cells which is released by parathyroid gland when the blood have low levels of calcium. Osteoclasts absorb calcium from the bones and add this calcium into the blood to increase the calcium level. If calcium is present in very high amount so this calcium is stored in the bones of the body and extracted when needed by the body.
Answer and Explanation:
The difference between a food chain and a food web:
<u>Food Chain</u>
- Only one possible direct line of energy going through organisms
- Consists of usually 4-6 organisms
<u>Food Web</u>
- Multiple links that branch off in a web-like form, with some organisms being interconnected with each other.
<u>The answer is the third option: A food chain represents one possible pathway that energy and matter can take in an ecosystem. A food web contains multiple, interconnected food chains and describes how energy and matter moves through an entire ecosystem.</u>

Answer:
The weight of a person on the moon is less, compared to their weight on Earth.
Explanation:
Gravitation is a force. Gravity is the force that tries to pull two objects toward each other.
Anything which has mass, also has a gravitational pull. The more massive an object is, the stronger its gravitational pull is. So because the moon iless massive than the earth, you will experience a less gravitational pull and therefore a you will experience less weight on the moon compared to your weight on earth.
EXTRA
The Gravitational pull is difined by the force that arises of masses of two objects in relation to their distance.
Earth's gravity is what keeps you on the ground and what causes objects to fall back to earth.
You can experience a change in gravitational pull on earth yourself, in an exelerating or decelerating elevator.
