Answer:
20%
Explanation:
Okay so the phrase apples in trees ( Adenine & Thymine ) and cars in garages (Cytosine & Guanine ) can help in this situation.
Since Thymine is 30%, Adenine will also be 30%. This gives you 60% of the DNA sample.
You have 40% left of the DNA sample so they must be Cytosine and Guanine.
Divide 40% by 2 and you get 20%. So you have 20% Guanine and 20% Cytosine.
Hope it helps!

The maximum amount of XeF4 that could be produced is 0.5 moles.
XeF4 = Xe (g) 2 F2 (g) (g)
Xe and F2 have a mole ratio of 1:2. Because of this, the reaction would be limited by F2 when there is 1 mole of Xe and 1 mole of F2.
<h3>What is mole ratio?</h3>
The mole ratio is the ratio of any two compounds' mole amounts that are present in a balanced chemical reaction.
A comparison of the ratios of the molecules required to accomplish the reaction is given by the balancing chemical equation.
A mole ratio is a conversion factor used in chemical reactions to link the mole quantities of any two compounds. A conversion factor's numbers are derived from the balanced chemical equation's coefficients.

Answer:
d. the relative age of these rock layers
Explanation:
Principle of superposition -
It is the form of relative dating , where the relative age of the rocks are determined .
It is on of the important principle for the study of geological stratigraphy .
According to the principle of superposition , the bottom most layer of the strata is one of the oldest one , and the top most is the most recent one .
Hence , the relative age of the rock can easily be determined by using this principle of superposition .
