The high-energy electrons produced by the chlorophyll are highly reactive so to move it from the chlorophyll to the other molecules it needs a carrier.
Hurricanes are not an example of density dependent limiting factors!
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>
