The statement that is correct regarding the troposphere and the stratosphere is The ozone layer is in the stratosphere. The third one is true. The ozone layer acts as a protection layer that prevents UV light.
<h3>What are the layers of the atmosphere?</h3>
The atmosphere is divided into many layers, with the troposphere close to the earth and the thermosphere toward the sun, as shown in the diagram. in between two layers, such as the tropopause, which is present between the troposphere and the stratosphere. In the stratosphere, the ozone layer is present, which prevents the sun's UV rays from falling on the earth, and the troposphere is the region where the clouds are formed.
Hence, the correct answer is the third option, which is "The ozone layer is in the stratosphere."

Answer:C. Creating helium from hydrogen in its core
Explanation: Stars produce energy majorly by nuclear fusion. The process of creating helium by merging hydrogen atoms to produce deuterium which in turn is converted to helium.
The process of respiration system would not function well if the lungs was made up of only one big alveoli.
<u>Explanation:</u>
The main role of alveoli is to help the lungs to breath, for ventilation, diffusion and perfusion. The process of respiration system would not function well if the lungs was made up of only one big alveoli.
Alveoli are tiny to help the flow of oxygen and carbon dioxide, it helps the oxygen flow into the lungs and remove the carbon dioxide. If the alveoli is just one and big, then it would be hard to flow the oxygen through lungs and remove the carbon dioxide.
Therefore, it is good to have many tiny alveoli than one big one or the rib cage that protect the lungs could go through some damages.
