What accounts for water's properties of adhesion and cohesion? The polar nature of water and the effects of hydrogen bonding
Adhesion is the tendency of dissimilar particles to cling to one another. While the cohesion is the grammatical and lexical linking within a sentence that holds the text together and gives the meaning. Cohesive forces are the intermolecular forces which cause a tendency in liquids to resist separation. The example of intermolecular forces are hydrogen bonding and Van der Waals forces. The differences between adhesion and cohesion are in adhesion, the molecules of different substances stick together and in cohesion, the molecules stick to each other
Water is a transparent, tasteless, odorless, and nearly colorless chemical substance. There are five main properties of water such as:

The bonding between the hydrogen atom and the polar nature of the water account for adhesion and cohesion characteristics of water.
Further Explanation:
The water molecules have two hydrogen atoms attached to an oxygen atom by a polar covalent bond. Carbon has an electronegativity of 2.55, which is very close to the electronegativity of hydrogen (2.20). Water is a good solvent because it is a polar molecule (polarity of a molecule is the separation of electric charge result to a molecule consisting of an “electric dipole moment” through a positively charged end and negatively charged end). The oxygen atom in the water molecule is more electronegative (tendency to attract electrons, as they are electron deficient.), while hydrogen molecule is electropositive as compared to the oxygen.
Due to this electronegativity difference, the shared pair of electrons is prominently pulled towards the oxygen atom, giving the atom a partially negative charge, and the hydrogen atoms a partially positive charge. The polarity of water is accountable for the “cohesion and adhesion” characteristics of water.

Answer:
The correct answer here is: D: They focus on the mental well-being of individuals.
Explanation:
The answer comes from learning what psychology itself is. Although it is true that psychology has grown from science, it is also an art, which means that it does not only base itself on pure hard scientific data, but also on observation. The focus of psychology is more than the biological, or physiological, actions inside a human brain; they focus on the way that the human mind works, the functions within the human mind, and especially how factors such as behavior, culture, society, cognition and personality work together to form a person. In essence, psychology seeks to understand the human mind and thus, through the development of knowledge, help people achieve mental well-being. This is why the best answer from the options is the last one.
Answer:
Proteins
Explanation:
Proteins are polymers made up of strings of amino acids. Proteins serve many functions in organisms including transport of molecules, structure, cell adhesion and as signaling molecules such as hormones.
