Osteoblasts are the cells in the bone tissue that are responsible to form bone tissue itself. This is the process that allows bones to grow. To counteract this process, osteoclasts, another type of cell from the bone tissue, have the role to break down bone tissue by molecular processes - enzymatic and chemical.
Answer:
According to earthobservatory.nasa.gov/,
"The ocean takes up carbon dioxide through photosynthesis by plant-like organisms (phytoplankton), as well as by simple chemistry: carbon dioxide dissolves in water. It reacts with seawater, creating carbonic acid. Carbonic acid releases hydrogen ions, which combine with carbonate in seawater to form bicarbonate, a form of carbon that doesn’t escape the ocean easily."

<span>Answer:
For ectotherms, on the other hand, body temperature mainly depends on external heat sources. That is, ectotherm body temperature rises and falls along with the temperature of the surrounding environment. Although ectotherms do generate some metabolic heat—like all living things—ectotherms can't increase this heat production to maintain a specific internal temperature.</span>
Answer:
The correct answer is OPTION C (Circumduction)
Explanation:
Circumduction is motions without clear opposites of the part of the body, an example is rotating the hand from the wrist. The answer is circumduction because this type of movement ensures the distal end of a bone moves in a circle while the proximal end remains relatively stable is particularly found in bones where the movements of the joints are opposite to each other example is the ball and socket joint movement. For circumduction to take place, the degree of distance between two bones of the body has to be decreased and sometimes straightened to increase the level of movement or motion produced, there must be a movement towards the middle of the body and sometimes joint movement away from the middle of the body. All these movements are in order.
