33. Which of the following is NOT an adaptation to hot temperature? A. Hi B. Increase in flexibility C. More H bond D. More proline E. More saturated lipids her proportion of guanine-cytosine nitrogenous bases 34. Which of the following is NOT true of water activity? A. It is the amount of water available to organisms B. It is reduced by interaction with solute molecules C. It is reduced by adsorption to surfaces D. Low concentration of salts reduces water activity E. Most microorganisms only grow at water activities around 0.98 or higher

Explanation / Answer

33. The adaptions for hot temperature include increase in flexibility of plasma membrane, increase in hydrogen bond, more prominent residues and more saturated lipids in plasma membrane.

Higher proportion of guanine-cytosine nitrogenous bases is not an adaption to hot temperatures.

Hence, the correct answer is option A.
