Mathematically the it would be D
but scientifically since eventually food and resources will start becoming scarce it would be A then as the ecosystem recovers it goes back to D <span />
Their bodies taper to points at both the snout and the tail, reducing water resistance. Also decreasing drag -- and therefore noise -- are dermal denticles, sharp scales that cover the skin of most shark species. Rather than bone, sharks have cartilage, which is much lighter and more flexible. In addition, their livers produce squalene, a fatty oil that helps them remain afloat. Their pectoral fins allow them to quickly change direction, dive and swim upward.

Answer:
<em>The four nucleotides that make up DNA are </em><em>adenine (A), cytosine (C), guanine (G), and thymine (T).</em>
<em>What happens if one of these nucleotides are swapped for another?</em>

<em>I hope this helps and have a great day!</em>
