Answer:
A change in pressure
Explanation:
This is because, the deeper you dive, the height of water above you creates a pressure on you. So, as the depth increases, the height of water increases, thus its weight on you, thus its pressure on you also.
Also, as you gain altitude as you climb a mountain, the height of air above you decreases. This thereby decreases the weight of air above you thus, decreasing the pressure of air on you. 
So, in both cases, there is a change in pressure as height or depth changes. An increase in height results in decreased pressure and an increases in depth results in increased pressure.
 
        
             
        
        
        
Density = mass/volume, volume = mass/density. 
Since the mass of the small cube equals 20 and the mass of the large cube is double it would be 40. 
Now plug in volume = 40 g/(7.87 g/cm^3). 
Thus giving you a volume 5.08 cm^3

Answer: Genetic information responsible for physical characteristics such as eye color, height, hair color, and skin color can be found in an organism's <u>DNA.</u>
<u>Explanation:</u>
Our genetic information is stored in DNA. DNA (Deoxyribonucleic acid) molecule is a double helix structure which carries information which used in development and growth of body and determines physical characteristics such as eye color, height, hair color and skin color.
