Specific heat means the heat required to raise the temperature of the unit mass of a given substance by a given amount (usually one degree).. The specific heat of water is high (1 calorie/gm/°C). This property ensures slow heating of water; maintain constant temperature of living organisms and environment.
Expansion upon freezing is what causes ice to be less dense as a solid than as a liquid. This means that ice floats in liquid water. Hydrogen bonding is the source of this rare property. Water freezes when its molecules are no longer moving around enough to break their hydrogen bonds.even though it doesn't seem like a very important property, but the fitness of the environment would drastically change if water were less dense than ice. All of bodies of water would eventually freeze over if ice did sink, making life on Earth impossible.
Versatility as a solvent Water is called the "universal solvent" because it dissolves more substances than any other known liquid. This is important to every living thing on earth. It means that wherever water goes, either through the ground or through our bodies, it takes along valuable chemicals, minerals, and nutrients.
Condensation because the water droplets are being formed by the water vapor in your breath against the cold window makinng condensation due to the drastic temperature difference between your breath and the window
Answer: Option A) Cells
Explanation:
The soft lining inside the mouth is an example of cell.
The inner lining of mouth is made up of the mucous membrane. Soft lining is consist of squamous epithelium also called as oral epithelium, which is a type of cell.
Epithilial cells are arranged in layers upon a basal membrane. It function to protect mouth against abrasion.
Hence the correct option is A) cells.
