Heyy there.
I'm thinking that it would be B. or D. but idk exactly which one it is.
I hope you figure out wat it is.
B. Thinnest under the oceans and thickest under continents
D. Least dense layer overall, consists of two layers of different thickness
Good Luck and enjoy the rest of ur day!! ^^
Carbon dioxide gas and oxygen gas
Tell me the question clearly I cannot understand
Thinking if I'm right Eukaryotes are more complex so they are capable of during more things, Prokaryote is smaller than eukaryotic. hope this helps out
after careful thinking and research and reading i am pretty confident its D
but dont take that answer because its pretty sketchy. so wait till someone else answers, because C also fits into the equation at some point. but yeah mainly D
