<span>For instance, during the concentration of salt in water affects the rate of osmosis because it will determine how much water should be transported or excreted or to be taken in. The cellular process is keen to the salt concentration of its system thus making sure to maintain balance between the salt concentration the right amount of water must also be in its area of release for any expected occurences. </span>
<span>Osmosis then is the movement of water particles from which has water and from which has not and to provide it with the sufficient H2O.<span>

Answer:
The correct answer will be option-
1. UV light strikes the skin and converts a steroid molecule into an inactive form of vitamin D.
2. Inactive vitamin D is transported to the liver where it is modified.
3. Vitamin D is activated under the influence of PTH.
4. Inactive, chemically altered vitamin D is transported to the kidneys.
Explanation:
Vitamin D is a fat-soluble metabolite which helps maintain the health of the bone by maintaining the calcium homeostasis.
The vitamin D is synthesized mainly in the liver and kidney from the biologically inactive precursor of vitamin D called ergocalciferol and Cholecalciferol.
The inactive vitamin is synthesized in the skin when the skin is exposed to UV rays.  The UV rays convert the 7-dehydrocholesterol, a steroid molecule to Vitamin D3, This inactive vitamin is then transported to the liver where it is converted to 25-hydroxyvitamin D. 
This vitamin D form is further metabolized in the kidney controlled and regulated by the Parathyroid glands.
 
        
             
        
        
        
Answer:
D, Secondary Succession
Explanation:
The answer is D because a habitat is an organism's home, a niche is the organism's role, and primary succession is when there are changes to land that contain no soil or life. Hope this helped :3
