Answer:
muscle cells in the legs of a marathon runner 
Explanation:
Mitochondria are the powerhouse of cells and serve as a site for the aerobic stage of cellular respiration. Cellular respiration is complete oxidation of nutrients in the presence of oxygen to produce a large number of ATP molecules. Therefore, the cells that require more ATP molecules as an energy source would most likely have a greater number of mitochondria.
Muscle cells are responsible for body movement. Muscle cells in the legs of a runner would require a constant supply of ATP during running since muscle contraction requires ATP. To sustain the continuous muscle contraction during the marathon, the muscle cells in the legs of the runner would have most number of mitochondria.

The vegetable oil is made up of chains of long fatty acids. These long chains of fatty acids are non-polar in nature, i.e, they do not interact through ionic forces rather by covalent forces. The phospholipids are also long chain fatty acids with an ionic head. The mixing of the vial of phospholipid in vegatable oil will lead to the formation of a micelle where the lipophilic ends of the phospholipid will be on the outside and the lipophobic end will be towards the centre of the micelle. 
 
        
                    
             
        
        
        
Answer:
small intestine
Explanation:
Umbilical. The umbilical region contains the umbilicus (navel), and many parts of the small intestine, such as part of the duodenum, the jejunum, and the illeum. It also contains the transverse colon (the section between the ascending and descending colons) and the bottom portions of both the left and right kidney.
