Joy has a dna sample from each of five unknown animals she wants to find the molecular mass of each sample to determine which sample belongs to which animal which method should she use

not sure if this is what you'r looking for eubacteria and archaebacteria

since there are no options posted i'll give you a few examples.

a dolphin's flipper, bird's wing, cat's leg.

fossil's are like over rated rocks like low key not gonna lie i don't get why we can't just call them old rocks like for real i mean i call my grandpa and grandma that smh
