Answer:
A great example of homologous structures are the wings of a bat and the arms of a human. Bats and humans are both mammals, so they share a common ancestry. Both a bat's wing and a human's arm share a similar internal bone structure, even though they look very different externally.
The reactants for fermentation are:
1.) Pyruvate
2.) NADH
3.) A proton
The products are a lactate and NAD+.
The process of fermentation results in the reduction of pyruvate to form lactate acid and the oxidation of NADH to form NAD+

sweepstake route
Explanation:
From the view of the horses, the ocean barrier would be seen as a <u>sweepstake route</u>.
<em>By definition, the sweepstake route refers to a rather difficult or dangerous path through which animals can move from one place to another. No animal would take this path ordinarily except by pure chance or when events leave no other option.</em>
