Answer:
Option 4 - Calcium
Explanation:
The <em>divalent cation </em>called <em>calcium</em> is needed to provide additional support to the bone matrix.
Calcium is considered one of the most <em>important components</em> in bone development. It helps in the formation as well as maintenance of bone. During the modeling and remodeling process of bones, calcium facilitates the formation of <em>semi-hard new tissues</em> which leads to the formation of new bone which is very hard.
Due to this reason, calcium is needed to create extra bone matrix support.
The answer is Because of to Earth’s rotation, the winds are deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. Coriolis effect causes the horizontal deflection effect, due to the rotating motion of the earth, to be felt more as you go closer to the poles and to decrease as you move near the equator. This same force is responsible for the rotation of large cyclones.
Don't pollute the Earth.
Don't need gas.
Answer: Selectively permeable means a membrane allows the passage of some molecules or ions and inhibits the passage of others. The capacity to filter molecular transport in this manner is called selective permeability.
Explanation:
Shortened: This means the membrane only allows some things to pass through while others can't.
