Answer:
Amino acids with non-polar side chains.
Explanation:
The class of proteins that is unable to form hydrogen bonds with water are the amino acids with non- polar side chains. This class includes the amino acids
Alanine
Valine
Leucine
Isoleucine
Proline
Phenylalanine
Cysteine
Methionine
Tryptophan
These are the nine proteins which are considered to be strongly hydrophobic. All these amino acids are hydrophobic in nature due to their side chains. Glycine is not added to this list as it does not have a side chain.
DNA is a negatively-charged molecule. Also cell membranes are negatively charged. The problem would be how to push this charges together? I<span>f you put some CaCl2 into the mixture, the CaCl2 will "split" giving 2Cl- and Ca2+. This last ion will be attracted by the negatively charged DNA and will "cover" it, hiding its negative charge. Hope this answers the question.</span>
I think the correct answer from the choices listed above is option D. <span>Astronauts and scientists conduct research studies aboard the International Space Station in a satellite that was built by sixteen nations. Hope this answers the question. Have a nice day.</span>
Answer:
Termites have cellulose-digesting protists in their guts.
Explanation:
Termites are able to access nutrients contained in cellulose due to their mutualistic association with some cellulose-digesting protists such as <em>Trichonympha</em> and M<em>ixotricha</em>. The protists produce cellulase in addition to other glycolytic enzymes that work together to convert cellulose to malate.
The malate produced is further metabolized to produce 
, hydrogen, acetate and energy in the form of ATP.
The protists get sheltered in the termite's gut in return.
