The answer is <span>a.Deletion.
Original gene: A B C D E F G H
New gene: A B C E F G H
As can be noticed, letter D is missing and that now there are only 7 letters instead of 8. In other words, a base or whole segment (depending on what the letters represent on DNA - bases or some random segments) is deleted. This change in chromosomal structure is obviously deletion.</span>
The answer is b. nematocyst. (hope this helps!)
your answer is a <em>habitat</em>
Answer: conservative model
Explanation: DNA isolated after one generation produced a single band which was a higher and intermediate in density between the heavy and light Nitrogen isotopic DNA used, showing that the first generation was a hybrid DNA. This observation fit with the dispersive and semi-conservative models only. And so at this generation, the conservative model was discarded.
Carbon dioxide and oxygen are two molecules that undergo this simple diffusion through the membrane.
