Which of the following statements is not true?
a. archaea and bacteria have different membrane lipids.
b. the cell walls of archaea lack peptidoglycan.
c. only bacteria have histones associated with dna.
d. only some archaea use co2 to oxidize h2, releasing methane.

c. False

This statement is incorrect because the DNA of bacteria is circular without histones.

answer: glucoamylase presented optimum activity at temperature of 55â°c, and, in the glycosidic bonds from the non-reducing ends of starch, resulting in the production of glucose. source and type of fermentation can affect the enzyme's properties
