Water in its liquid form has a boiling point temperature close to 100°C. As a result of the network of hydrogen bonding present between water molecules, a high input of energy is required to transform one gram of liquid water into water vapor, an energy requirement called the heat of vaporization.
Cohesion is responsible for the transport of the water column in plants. Adhesion is water attracted to other material.
Water has a greater surface tension than most other liquids because hydrogen bonds among surface water molecules resist stretching or breaking the surface.
Specific Heat is the amount of heat that must be absorbed or lost for one gram of a substance to change its temperature by 1*C.
Density is when hydrogen bonds in water expand as it warms and contracts as it cools. The hydrogen bonds keeps the molecules far enough a part to make ice have fewer molecules.
Considering the nitrogen cycle, all organisms depend on bacteria to produce and maintain adequate nitrogen in the environment by eating the plants that contain bacteria which contain nitrogen.
Option: (B)
<u>Explanation:</u>
Nitrogen is a main element in the nucleic acid of both RNA and DNA which is most important for all living creatures and biological molecules.
When plants doesn’t get enough nitrogen it doesn’t produce amino acid, without amino acid plant cannot make special proteins.
Amino acid is building block for DNA which tends to the generation of organism.
Nitrogen fixation is a process where bacteria convert atmospheric nitrogen to usage form for plant and animals get nitrogen by eating those plants.
