The water starts boiling at 100°C and at this stage all the water will be converted into vapor which is not possible as the temperature of water never reaches 100°C.
It has low vapor pressure and low volatility. Example: More petrol will be converted into vapor as compared to water at the same temperature.
hence, this property of water allows it to remain in liquid state and not being dried out during summers.
The answer would be D. Huntington's disease presents symptoms in humans after many have already reproduced; therefore, they are unaware that they passed on Huntington's disease.
The cactus spines keep predators away and prevent different organisms from eating it. This helps it to survive in the desert. Another adaptation is very thick, waxy cuticle help to reduce water loss by evaporation.
