Water is a unique molecule which contains inter-molecular forces like vandar wall's forces and hydrogen bonding that results in extremely strong bonding forces among water molecules.
Cohesion and adhesion are the properties of water which refer to the fact that water molecules are not only very strongly attracted to water molecules but also to other polar molecules of any type.
This is the cohesive nature of the water which makes water a water drop and it is the adhesive nature of water due to which water takes the shape and available space in a glass or jar of water .
How these properties are a result of bonding between atoms?
Cohesive properties:
- We are well aware of the fact that water is composed of one atom of oxygen and two atoms of Hydrogen.
- The two hydrogen atoms align themselves in such a way that oxygen is in middle of them. Due to great electronegativity difference Oxygen gets a partial negative charge while Hydrogen atoms get partial positive charges.
- Now one oxygen atom of one one water molecule attracts the partial positive charged hydrogen atom of another water molecule, and this attraction causes the bonding. This type of inter-molecular forces of atom gives water cohesive properties.
Adhesive properties:
- If we talk about adhesive properties through which water is attracted to other materials of polar nature, these adhesive properties are also due to same nature of bonding.
- Any polar compounds can easily get bonded with water due to polar nature of water molecules. You can see the attached figure for better understanding of bonding properties of water.

Each mRNA 3-base sequence, called a _codon_ , matches with a tRNA sequence called the _anticodon_ . The tRNA also carries the specified _amino acid_ , used as a building block for a protein.
Answer:
Selective breeding.
Explanation:
Selective breeding method is used in order to produce more bushes that have the same kind of berries. In this method, Saskatoon bush which is a wild bush can be crossed with another bush belongs to the same family so the new seeds produced having the characteristics of Saskatoon bush and is able to produce large and sweet berries just like berries of Saskatoon bush.
