Anew organism is discovered in the forests of costa rica. scientists there determine that the polypeptide sequence of hemoglobin from the new organism has 72 amino acid differences from humans, 65 differences from a gibbon, 49 differences from a rat, and 5 differences from a frog. these data suggest that the new organism is more closely related to

Frog

Explanation: It is the frog because the less differences there are, the more closely related it is to the organism.

frog

Explanation:

It is given in the question that the new organism that has been discovered at Costa Rica has 5 differences from a frog. So the new organism is suggested to have been closely related to the frog species because among the other species ( that is humans, gibbons, rat ), the new organisms shows very less differences with the frog species. So it is concluded that the frog species and the new organisms are closely related.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
