Answer: c.composition, temperature, and function.
Atmosphere can be classified into composition, temperature, and function.  The composition has two region, heterosphere and homosphere.  The temperature will be divided into thermosphere, mesosphere
, stratosphere, troposphere
. The function will be divided into ozonosphere and ionosphere 
 
        
             
        
        
        
The answer should be 1, hypertonic. 
Seawater is highly concentrated in salt, and with that being said, it has a low concentration of water molecules. 
Hypertonic means the solution has a lower water concentration than the other side (cell), vice versa for hypotonic, a high water concentration than the other side of the solution, and for isotonic, it means that both sides of the solution have the same water concentration. 
So, the answer should be 1, hypertonic. 
In addition, when your cells are exposed to hypertonic solution, the water molecules in your cells will start flowing out of the cells, to the outside, due to the difference in water concentration leading to osmosis. Your cells will lose so much water that they may even shrink!

Answer:
n a population, more individuals are born than can survive. The available resources in nature are finite (food, water, space, etc.) and the environment is not able to support unlimited growth of a population. This causes an inevitable struggle for existence among individuals (continual struggle for existence).Explanation:
