10) This type of weak bond is found between a) a base. water molecules and is also important for the cture of large molecules like proteins and c) an acid. d) a neutral solution. DNA. a) polar covalent 17) Put the following in order from smallest to nonpolar covalent (1) amino group (2) electron (3) dipeptide (4) oxygen atom (5) protein with 50 amino acids (6) amino acid ) ionic nonpolar 1)NEGATIVE ions form when: there is a gain of electrons b) there is a loss of electrons c) there is a loss of protons d) there is a loss of neutrons a) 1, 2, 3, 4, 5, 6 b) 2, 4, 1, 6, 3, 5 12) An IONIC bond is: a) an example of a chemical bond which will )2, 1,4, 3, 6, 5 produce organic molecules formed when there is a transfer of electrons from one atom to another formed when there is a sharing of electrons between two or more atoms an example of a chemical bond which forms chains of carbon atoms none of the previous choices are correct 4, 2, 6, 1, 5, 3 18) A monomer is related to a polymer like a) a brick is related to a wall. a molecule is related to a c) d) e) a) c) b) a cell is related to a tissue all of the above are true. c) 19) 1n the graph to the below, which solution is the best buffer? 13) Electrolytes are substances that form covalent bonds with water ionize when dissolved in water cannot conduct electricity when in solutiond) pH Changes in Response te Adding Acid D d) are not found in the human body in any 20) In the graph to the appreciable amounts 14) The LOWER the pH number: a) the greater the hydrogen ion concentration right, will be 6 the more alkaline the solution will bebuffer is c) the greater the hydroxyl ion concentration best for keeping things at a neutral pH? a) A (b) B c) C d) will be d) the more basic the solution will be e) the more likely H+ will equal OH- 15) If you dissolved HCI in water, what would happen a) There would be less H+, and the pH would D 21) This functional group be acidic. be basic would be acidic would be basic b) There would be less H+, and the pli would a) a phosphate group b) a fatty acid c) an amino group c) There would be more H+, and the pH d) There would be more H+, and the pH 16) A solution that resists changes in pH when a carboxyl group D a phosphate group c) an amino group 22) This functional group is ) a fatty acid acid or base is added to it is called: 56

Explanation / Answer

10 - The correct answer is option C that is hydrogen bond.

Positively electro negative hydrogen and negatively electro negative oxygen forms hydrogen bonds between them and it is required for structure of water molecule and protein structures.

11 - The correct answer is option A that when there is a gain of electron a negative ion is formed.

12 - The correct answer is option B that is ionic bond is formed when there is a transfer of electron from one atom to another.

13 - The correct answer is option B that is electrolytes are substances that ionize when dissolved in water.
