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. Destruction of tundra vegetation will likely result in melting of the permafrost. The tundra ecosystem is extremely sensitive to disturbance with little ability to restore itself. The melting of the permafrost will <span>cause the collapse of ground and loss of soil. </span>
Pioneer species are often hardy plants with Adaptations such as long roots, root nodes containing nitrogen-fixing bacteria, and leaves that employ transpiration.
Answer:
Well, it’s because tattoos have to get that ink deep enough that it won’t get washed away but not too deep so it remains visible — the ideal location ends up being right next to your skin’s pain receptors.
<span>Aerobic respiration
uses oxygen while anaerobic respiration does not. In aerobic respiration, it
occurs in most cells. It releases High amount of energy at 36-38 ATP molecules
and it reacts with glucose and oxygen. It produces carbon dioxide, water and
ATP. While in Anaerobic respiration, it occurs mostly on prokaryotes. It releases
lower energy between 36-2 ATP molecules and it reacts with glucose and electron
acceptor which is not an oxygen. It produces carbon dioxide, reduced species
and ATP. The site of both respiration is in the cytoplasm and mitochondria. -ahnnahly</span>
