Answer:
A.The hole in the ozone layer
Explanation:
• Montreal protocol is an international treaty that was signed to control the use of substances that are resulting in the depletion of the ozone hole. 
This treaty was signed in the year 1987 and became effective form 1989.
• Since the time that this treaty has come into force, there has been a significant improvement in the ozone hole that was observed over Antarctic as it's size has decreased. 
• This improvement has been possible because the treaty helped to phase out chemicals such as chlorofluorocarbons, carbon tetrachloride, etc. that are responsible for ozone hole depletion.
 
        
             
        
        
        
Answer:
The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All living cells must carry out cellular respiration. Cellular Respiration uses ATP as energy.

The answers would be:
Igneous Rocks - They are made from hot magma.
Sedimentary Rocks - They are made from weathered pieces of rock.
Metamorphic Rocks - They are rocks, small or large which reformed due to high temperature.
If you'd like to know more, read on:
Igneous rocks are formed when hot magma is cooled and then it hardens into a rock. The word igneous comes from the word, "ignis" which means "of fire. They can be formed beneath the Earth or on the surface. 
Sedimentary rocks are formed from weathered pieces of rock. These pieces are called <u>sediments</u>. They can also be made out of other material. When these sediments settle, it continues to do so until so much sediment accumulate and they start to press down on each other. The sediments then start to go through compaction and sedimentation which for a sedimentary rock. 
Metamorphic rocks form under heat and pressure. They are squeezed and shaped and go through <u>metamorphosis </u>or go through change. A metamorphic rock can be formed from any other type of rock as long as it goes through changes due to intense pressure and/or heat. 
 
        
             
        
        
        
The maximum to minimum body water loss occurs by: Urine production, Skin losses, Lung respiration and minimum by Feces
<h3>What are the ways in which body loses water ?</h3>
Through breathing, sweating, and peeing, the body continuously loses water. You become dehydrated if you don't drink enough water or other liquids.
The majority of fluid loss happens through the stools, sweat, and urine, but it's not only those things. The quantity of body fluid lost daily through the skin, respiratory system, and water in the feces that cannot be readily measured is known as insensible fluid loss.
Physical exercise also influences increased respiratory water loss due to the increased expiratory volume and frequency of breathing. Various environmental elements like temperature, humidity, radiation, and atmospheric pressure mostly affect sweating and urine water loss.
