Answer:
The correct answer is B. No jaws. The new species resembles an ostrachodermi.
Explanation:
Ostrachodermi is an extinct class of agnate fishes, considered as the most ancient vertebrate. They were little filtering organisms, with no mandible or jaws, and no paired fins. Their bodies were covered by squama, bony plates, and shields. They used to move in the bottoms when they were feeding on detritus.
The grass energy that mouse receive is 10%.
The 10% rule states that only 10% of available energy is transferred as food is consumed from one trophic level to the next. It's important since it generates the pyramidal structure and establishes the number of organisms at each trophic level. Heat, inedible components, and the mere reality that not all prey are consumed by predators all result non energy loss.

These are the possible genotypes RR, Rr, Rr, rr
First 3 carries dominant gene for tongue rolling, so they can do it,
while the 4th genotype rr is homologous for recessive, and he/she can't
perform tongue rolling.
