1. Water is a polar molecule that repels the non-polar molecules. Polar molecules such as water have partial charge between its atom while hydrophobic molecules are neutral. The non-polar molecules that are repelled by molecules of water are called hydrophobic molecules. Examples of hydrophobic molecules are fats and oils.
The answer of (1) is Hydrophobic.
2. Atoms that have an equal number of protons and electrons are neutral or have zero net charges. When atom losses an electron, the atoms gain a positive charge. When an atom gains an electron it tends to develop a negative charge. An atom that gains or loses an electron develops a charge on it, and such atom is known as the ion. The atom that gains positive charge is called cation and the atom that gains negative charge is called anion.
The answer of (2) is Ion.
3. The pH (Power of Hydrogen) is the value that indicates the degree of alkalinity or acidity of a solution. pH scale is used to measure the pH value of a solution. The pH scale ranges from 0-14. The mid value of the pH scale indicates the neutrality. pH 7 is the pH that represents the neutrality of a solution on a pH scale.
The answer of (3) is 7.
4. pH is the measure of the hydrogen ion concentration in a solution. A buffer is a solution that resists the change in the pH of a certain solution. A buffer solution is either made up of a weak acid and its conjugate base or it is made up of a weak base and its conjugate acid. The pH of a solution can be maintained within narrow limits by buffers.
The answer of (4) is buffer.
5. The living organisms on our planet are carbon-based. The Carbon atom assists as the backbone to which nitrogen, oxygen, and hydrogen are connected. The atom predominantly found in the living system is carbon.
The answer of (5) is carbon.
6. Monomers are small molecules or atoms that bind together to form a polymer. Sugars, nucleotides, amino acids, and fatty acids are few major types of monomers. Example of a polymer is a polypeptide chain made up of amino acids.
The answer of (6) is the polymer.
7. Deoxyribonucleotide (DNA) and ribonucleotide (RNA) are known as nucleic acids. The building blocks of DNA and RNA are nucleotides. In DNA and RNA, these nucleotides are linked covalently. The phosphate group of the 5th carbon of a nucleotide covalently binds to the pentose sugar linked with third carbon of another nucleotide.
The answer of (7) is nucleotides.
8. Amino acids are monomers that combine together to form a polypeptide chain or a protein. Proteins are the polymers that are made up of amino acids. Therefore, the building blocks of proteins are amino acids.
The answer of (8) is proteins.
9.The covalent bonds in the hydrocarbon chain of fatty acid help in identifying the level of saturation of a fatty acid chain. In case all the carbons in the hydrocarbon chain of fatty acids are covalent single bonds then the chain is saturated. Presence of one or more than one carbon to carbon double bond in the fatty acid chain, then the fatty acid is called unsaturated.
The answer of (9) is saturated.
10. Sugars are a type of carbohydrates as they are made up of carbon, oxygen, and hydrogen. Some examples of sugars are fructose, glucose, lactose, and sucrose.
The answer of (10) is oxygen.
11. Alanine is an amino acid. Amino acids are the compounds that consist of carboxyl and amine functional groups, with a side chain. The side chains are specific to each amino acid. The main elements of each alanine are carbon, nitrogen, oxygen, and hydrogen.
The answer of (11) is nitrogen.
12. Nucleic acids are made up of nucleotides. Nucleotides are made up of a phosphate group, a 5-carbon sugar, and a nitrogenous base. The main elements of nucleic acids are carbon, nitrogen, oxygen, hydrogen, and phosphorus.
The answer of (12) is phosphorus.
