<span> Dimers formed by a normal protein will run through the gel-filtration column faster than a mutant protein Y monomer. Choice (b) is unlikely, because gel-filtration columns separate proteins on the basis of size, not charge or affinity for small molecules. Choice (c) is unlikely, because if the mutant protein were larger than normal it would be less able to enter the porous beads and would run through the column faster than the normal protein. Choice (d) is unlikely, because a small change in shape without a change in size </span>
<span>would be unlikely to have a major effect on the behavior of a protein in a gel-filtration column.</span>
I'd say pollution and waste being dispersed the wrong way
Answer: Infrared radiation.
The answer is:
the change in red blood cell volume is principally due to the movement of WATER.
<span>The beak shapes of the finches on the Galapagos islands differed in shape and size.
Finches arrived on the Galapagos islands approximately 2 millions years ago. Darwin noticed that finches on each of the islands were different, resulting in the discovery of 15 distinct kinds of finches.
In some cases the beak shapes differed due to the food available on each island, such as large strong beaks for breaking open nuts, while others ate insects.
Other differences included body shape, song, and feeding behaviors.</span>
