They have very sharp teeth to cut through their prey, or try to escape if they are trapped
Their bodies are very narrow, enabling them to be very quick and nimble, it also enables them to hide it tight spaces
Their teeth also enables them to escape a fishermen's line ( I'm a fishermen and I've lost many barracuda due to those teeth.)
I hope this helped
<span>a. They have homologous structures because they have a common ancestor.

<span>The answer to this question would be: e. increase the rate of the glycolytic reactions.
</span>Lack of oxygen limits the possible chemical reaction that can be done to produce energy. In the anaerobic environment, fermentation of glucose would be the source of energy for bacteria. The net amount of ATP can't be increased, so you need to increase the rate instead.
No it is not balanced because there are four oxygen atoms in H2SO4 while there 5 oxygen atoms in the reactants side
