Answer:
Epiglottis
Explanation:
The epiglottis is a leaf like structure tat rests above the voice box/larynx and its main function is to seal off the windpipe during eating, so that food is not accidentally inhaled down the wind pipe. When water goes down the wrong pipe, it goes down the windpipe instead of the oesophagus resulting in water going to your lungs which causes the coughing as a protective reflex to clear the windpipe
Enzymatic activity will increase as more enzyme is added but will stop once all the substrate has been reacted with as it has nothing to act on
Lets see this with example
if you put a red blood cell in a glass of water the red blood cell is in hypotonic solution and that water flows into less concentrated area ( in to the red blood cell ) which eventually will swell and burst.
Another plot is when we put the same red blood cell in a glass full of salty solution which is Heterogeneous solution. In these case the water will move out from the cell to the solution which cause the cell to shrink.
Answer:
B. The cell would be unable to maintain a stable internal environment.
Explanation:
If cell membrane was made up of polar substance then it would have dissolved in polar solvents like water ( universal polar solvent), and the cell would have ceased to exist.
