Which of the following statement best describes how bacteria in a hot spring control the fluidity of their plasma membrane? A. They decrease the percentage of lipids with unsaturated hydrocarbon chains in their plasma membrane
B. Because they don't synthesize cholesterol, they cannot control membrane fluidity and therefore have a very fluid plasma membrane.
C. They use cholesterol to prevent membranes from becoming too fluid.
D. They form lipid rafts to prevent too much fluidity
E. They increase the percentage of lipids with unsaturated hydrocarbon chains in their plasma membrane.

Arational expression has been simplified below. (x-5) (x+1)/3(x+1) = x-5/3 for what values of x are the two expressions equal

What best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and already fulfills the octet rule. bromine forms covalent bonds because it has many electron shells, but neon has only two electron shells and is tightly bound to its electrons. neon forms covalent bonds because it can share its valence electrons, but bromine has seven valence electrons and can gain only one more electron. neon forms covalent bonds because it has only two electron shells, but bromine has many electron shells and will lose electrons in order to fulfill the octet rule.
