I belive the answer would be "A" because the cell would be trying to delute the solution on the outside, and strenghting the solution on the inside.
 
        
                    
             
        
        
        
The answer in agriculture.
<span>In agriculture, fertilizers are commonly used. But when they reach the bay, they could be cause of escessive nutrients. </span><span>Algae use the presence of increased nutrients and enhance their own growth. It is known that they produce an oxygen in the photosynthesis, so it is not a problem while they are still alive. But when these organisms die, their decomposition begins. For the process of decomposition, the oxygen is needed and ultimately it will be depleted from a body of water. This will lead to the death of aquatic animals that depend on oxygen.</span>
 
        
        
        
<span>The
answer is a fecal occult blood test (FOBT) that checks for hidden (occult)
blood in the stool (feces) by use of a microscope.  The major disadvantage is that it is not very
accurate because it is not a 100% reliable as an indicator of colorectal
cancer. Sigmoidoscopy is often undertaken following a positive FOBT</span>
        
             
        
        
        
Vacuoles are storage organelles that are found in both animal and plant cells. They store food or any other forms of nutrients, they also store waste products so as to protect the contamination of the cell environment. These waste products are sent out of the cell via vacuoles. In plants the vacuoles are larger than in animals. The vacuole provides plant nourishment in the scarcity of water in the external environment hence, prevents the wilting of plants.
