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!

For any question comment me
400 BTU of wasted heat energy is present in the form of electricity.
<h3><u>Energy sources and usage</u></h3>
- Potential energy sources include fossil fuels like coal, oil, and natural gas. Other energy sources include hydro, solar, and wind.
- Additionally, nuclear energy may also come from radioactive materials.But energy will constantly lose its strength.
- Industries would never be able to derive a full amount of energy from their sources.We can only obtain 60% of the energy in ideal situations, such as the Carnot engine. This is if the case is ideal. Actually, we receive considerably less than this for roughly 40%.
So, when efficiency is 60%, energy is used 60% of the time and lost 40% of the time. Thus, according to question, the energy that is wasted is:
1000 BTUx (40/100) = 400 BTU
