By keeping your skin hydrated, you can help keep the elastin that your skin needs to keep from scarring. Using topical creams such as coconut oil will keep your skin moisturized and make stretch marks less likely. Even without treatment, almost all stretch marks will fade over time.

Answer:
<u><em>Phospholipids are amphipathic. </em></u>
Explanation:
Amphipathic compounds can be described as compounds which have both polar and non- polar parts. 
The phospholipids have polar heads. The tails of phospholipids are non-polar. The tails are made up of fatty acids which are insoluble in water. It is due to the amphipathic nature of phospholipids that the cell membranes are made up by it. The property of phospholipids helps the cell membrane to filter which molecules to let enter into a cell and which molecules should not be taken into the cell.
 
        
             
        
        
        
What is the role of water in the photosynthetic process? Water splits into oxygen, hydrogen ions, and electrons to replace the lost electrons of photosystem II in the light dependent reaction. Also as hydrogen ions pass through ATP sythase, ATP is formed to use in the light independent reactions.
