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.
Answer:
Mushrooms and plants all need energy to grow. But the sources of their energy differs.
Explanation:
Sun is the ultimate source of energy for any living organisms to grow and make their food. While plants takes energy from the sun directly and make their food, while the mushrooms which is not a plant does not take energy from the sun directly.

Plants have chlorophyll. And they direct absorb energy from the sun light to make their own food.
Given what we know, we can confirm that the principle from the cell theory that supports this finding is that existing cells are produced by other living cells.
<h3>What is the cell theory?</h3>
The cell theory is a scientific theory proposed in the middle of the 19th century. It attempts to explain the formation and role of cells. There have been many wrongful iterations of this theory until arriving at the current version that is widely accepted today.
Therefore, we can confirm that the principle from the cell theory that supports this finding is that existing cells are produced by other living cells.
