BIOLOGY 102 FINAL QUESTIONS WITH 100% VERIFIED ANSWERS (GRADED A+) Which of the following questions could NOT be used to develop a testable hypothesis? A - Does exposure to secondhand smoke affect the probability of developing lung cancer? B - Do organic vegtables contain harmful substances? C - Should everyone drink bottled water only? D - Does a can of vegetable juice contain more salt than the same size can of iced tea? - CORRECT ANS-"Should everyone drink bottled water only?" The boundary structure that physically defines a cell is... A - a double phospholipid membrane. B - Protein channel C - Hydrophilic layer D - Phospholipid side chain - CORRECT ANS-a double phospholipid membrane. Ionic bonds... A - Result from the sharing of electrons between atoms. B - for only between polar molecules C - form between atoms that develop opposite charges. D - result from the natural repulsion, it could be predicted that ice floats on liquid water. - CORRECT ANS-form between atoms that develop opposite charges. Based only on the following illustration, it could be predicted that ice floats on liquid water because... A - the crystal structure of ice is more regular than that seen in liquid water. B - the distance between water molecules in ice is greater than in liquid water. C - the cool temperature of ice reduces the extent of molecular motion relative to liquid water. D - when ice forms, the hydrogen bond in the water molecule becomes nonpolar; ice behaves like oil. - CORRECT ANS-the distance between the water molecules in ice is greater than in liquid water. Chemists often represent the structure of atoms using p, n, and e to indicate the numbers of protons, neutrons, and electrons; which atom would have an atomic mass of 30? A - 10p, 10n, 10e B - 15p, 0n, 15e C - 15p, 15n, 15e D - 0p, 15n, 15e - CORRECT ANS-15p, 15n, 15e The Golgi apparatus... A - is the place where a cell's genetic material is stored. B - sorts proteins and lipids and sends them to their final destination. C - captures energy from sunlight and sends it to the mitochondria. D - creates energy by converting ribosomes to proteins. - CORRECT ANS-sorts proteins and lipids and sends them to their final distination. How many atoms are present in a single molecule of C8H10N4O2? A - 4 B - 8 C - 12 D - 24 - CORRECT ANS Continues...
