The answer to the biology question being presented above would be 'sexual reproduction'. Genetic variability is the most important result of sexual reproduction. In this variability, the genes are varied through sexual union and reproduction.
Answer:
Water has several very unique properties, like surface tension, cohesion, and adhesion because water is polar and every water molecule electrically attracts the neighboring water molecules.
Explanation:
Water is a universal solvent and has several unique properties like surface tension, adhesion, cohesion, high specific heat, etc.
In a water molecule, the oxygen atom's nucleus attracts electrons more strongly than the nuclei of hydrogen atoms. The negatively charged electrons are pulled toward the oxygen atom's nucleus and away from the hydrogen atom nuclei. As a result, a negative electrical charge occurs in the middle part of the water molecule near the oxygen atom and a positive charge near the other parts of the molecule (hydrogen atoms). This unequal distribution of electrical charge between different parts of the water molecule (polarity) makes it a polar molecule.
The positive part of one water molecule (hydrogen atoms) is attracted to the negative parts of neighboring water molecules and as a result, hydrogen bonds are formed between hydrogen and oxygen atoms of adjacent water molecules. These hydrogen bonds between molecules help hold water molecules together.
