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.
A plant without chlorophyll would not be able to photosynthesise because chlorophyll serves to absorb sunlight, which is used to break apart the bonds in water during photosynthesis. A plant that is unable to photosynthesise is not able to create glucose, hence it would likely die unless it was receiving glucose through another source. This is because the plant relies on the energy it gets from breaking down glucose for important internal functions.
Answer: As the temperature of the water goes up, the amount and spatial extent of the kelp goes down. These changes could result in dramatic habitat loss leading to reduced ecosystem productivity and the extinction of many invertebrate species.
For body cells to function properly, the following conditions need to be balanced:
1. BLOOD SUGAR
2. BODY WATER
3. BODY TEMPERATURE.
These three factors have to be in the right proportion for the cells and the body as a whole to function properly and to maintain homeostasis.
Blood sugar is the source of energy in the cell and it is required by all cell for carrying out the normal biochemical reactions in the body. The biochemical reactions in the body use water as a medium of reaction, thus the water balance in the body must be maintained. The body temperature also need to be kept at the normal level or else the normal biochemical reaction of the body will not be able to take place, due to the fact that incorrect temperatures deactivate the enzymes that mediate biochemical reactions.
