32. interpret visuals use figure 26-9 to identify the two characteristics that were required forpoints animals to move from aquatic environments to land. why were these characteristics necessary?

The two features are four limbs and lungs. These features were essential for animals to move from aquatic to land.

Lobe-fins are not common among the living fish and are only exhibited by the lungfish and coelacanth. However, the lobe limbs are exhibited by various living species, like humans. This is due to the fact that all the tetrapods, that is, four-limbed vertebrates, share a more recent common ancestor with the lungfish and coelacanth.

Tetrapods evolved from a group of species, which were aquatic and exhibited scales and fleshy fins. However, they also had lungs, which they used to breathe oxygen. About 360 to 390 million years ago, the predecessors of these species started to thrive in shallower waters and finally moved to land.

With this, they experienced natural selection, which assisted various adaptations for a terrestrial way of life. The modern humans still persist the proof of the aquatic past in the manner the arms and legs are attached to the body.

hey, i believe your answer would be d. sugar ribose and the base uracil. i believe this is the answer, because rna consists of sugar ribose, adenine, guanine, cytosine, and uracil.

your first option is incorrect, because that's dna. where it consists of sugar deoxyribose, adenine, guanine, cytosine and thymine.

your second option is also incorrect, this is because sugar deoxyribose is in dna, and uracil is in rna. these two do not make sense together.

your third option being incorrect, because sugar ribose is in rna, but not the base of thymine. rna consists of uracil, not thymine.

lastly your fourth option being correct! this answer is correct, because both sugar ribose, and the base uracil are in rna! ~

answer is d. sugar ribose and the base uracil.

ur answer is e & d
