Answer:
The correct answer would be option D.
Explanation:
Pollen of a plant is a gamete, that contains half of the alleles are required to produce the plant. Pollen fuse with stigma and complete the required alleles or genetic information.
Possible combinations in pollen would be one allele from each trait in every form either dominant or recessive. So ST, St, sT, st. would be the correct possible genetic combination present in a single grain.
Thus, the correct answer is option D.

Answer:
It is the primary mechanism for evolution.
Explanation:
Answer:
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.
