I feel like this question has more to do with water and its changes of states more than just freezing water. Water has a high specific heat, which means that it takes more energy to either boil or freeze than many other types of substances. This is unusual about water because it has a low molecular weight, which is normally associated with a smaller need for energy to change states. Is water didn't require this extra energy, then it water would freeze much more easily. This would be detrimental for many biological ecosystems. Think about how the world would be if water froze at say 60 degrees F, rather than 32. This would significantly effect the world as we know it.
Answer:
Air pressure is influenced by the differences between hotter and cooler pockets of air, or fronts.
Explanation:
When atmospheric pressure is low, air is pushed down toward the surface, meaning rain and moisture don't accumulate. This often also leads to high humidity near the surface of the Earth, where people experience weather.
Answer:
The chemical basis of Chargaff"s rule is the bonding properties of the DNA bases.
Explanation:
According to the Chargaff"s rule in a DNA molecule the total number of purine bases are equal with the total number of pyrimidine bases that means
Adenine +Guanine=Thymine +Cytosine
In simple words the rule is based on the 1:1 ratio of both purine and pyrimidine bases.
Answer:
4
Explanation:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel
