Answer:
1
Explanation:
5÷2=2.5 that means it's 2.5 L for every one ATM
Missing question: Z:X = 7:1 A:Z = 2.5:1 A:Z = 2.2:1 Y:X = 11:1.
Answer is:<span> Z:X = 7:1 and Y:X = 11:1.
Law of multiple proportions or Dalton's Law
said that the ratios of the masses of the second element which
combine with a fixed mass of the first element will be ratios of small whole
numbers.
In this example ratios are whole numbers, A:Z = 2.5 : 1
and A:Z = 2.2 : 1 are not whole number ratios.</span>
Answer: D. Insects
Fossils that are preserved in the Burgess Shale are mostly the remains of soft-bodied organisms.
So the answer is D because insects don’t really have bones like the rest of the other options. They have exoskeletons which protects their organs and gives them support for moving around.
