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!

Answer:
It's because removal of electron from an atom, reduces the size of an atom.
Explanation:
When an electron is removed from an atom, it becomes an ion and in this case it will become a postive ion.
When an electron is removed from an atom, the charge balance of an atom is disturbed and positive charge increases in comparison to the negative charge. This results in increase nuclear (positive) charge which exerts greater attraction on the remaining electrons and as a result the remaining electrons are more strongly attracted by the nucleus and in this way the atomic size is decreased. Due to this increased nuclear attraction and reduced atomic size, it bcomes difficult to remove more electeon from the positively charged ion of reduced size. This is the reason that each successive ionization of electron requires a greater amount of energy.
The ionization energy has inverse relation with the size or radius of an atom. This also justifies the reason that why each successive ionization of an electron requires greater amount of energy.
