Which statement below regarding membrane structure and membrane transport is true?
a. increasing the proportion of unsaturated fatty acids of membrane phospholipids would be most likely to occur as environmental temperatures become warmer.
b. cyclization of membrane phospholipid fatty acids (like cyclopropane) would confer more rigid, straighter hydrocarbon chains
c. membrane lipids of by hyperthermophilic archaebacteria are of the ester-linked fatty acid type also found in non-archae bacteria and eukaryote membranes, respectively.
d. cell wall-containing bacteria and archaea tend to possess a slightly hypotonic interior to create a positive turgor pressure thereby it to maintain cell shape and form.
e. group translocation is a transport mechanism that moves molecules via facilitated diffusion.

Recently, crops of vegetables such as lettuce and green onions have been contaminated, while they are still on the farm, with bacteria that cause food poisoning. how will science influence the way the government responds to prevent an increase in food-borne diseases? because science has shown that lettuce and green onions are not nutritionally valuable, the government may pass laws that ban the sale of lettuce and green onions. because science has shown that there is no way to prevent bacterial contamination, the government may pass laws that punish businesses that buy lettuce and green onions. because science has shown that the washing of hands prevent the spread of infectious diseases among people, the government may pass laws that require hand washing by everyone who handles food. because science has shown there are ways to find the source of the contamination, the government may pass laws that require farm practices that reduce the contamination of lettuce and green onions.
