6. What trait separates lizards and snakes from crocodiles and
alligators?

the backbone of the dna and rna compound is sugar phosphate.

age range would be the answer

not only is it colder, it also becomes darker, less salty, and more dense.

the main thing i would use is bricks because if there is a hurricane, there is a great possibility for the house to still stand. and i would also use plexiglass windows instead of regular windows because plexiglass isn't prone to breaking.
