18%. If a cell contains 32% cytosine then it contains the same amount of its base pair, guanine. That means 64% of the cell is cytosine and guanine. The remaining 32% must be adenine and thymine, of which there should be equal amounts. Therefore to fine the amount of thymine divide 32 in half, which gives you 18%.
I don't think this is correct, but the four bases are adenine, thymine, guanine, and cytosine. So, if there is 32% cytosine then there has to be 32% guanine because that pairs up with cytosine. so percentages are out of 100, meaning that 100-64=36 which is how much percent we have left for the other two bases. 36/2=18 which would be the percent of adenine and thymine because those two pair up in dna.
Increasing Substrate Concentration increases the rate of reaction. This is because more substrate molecules will be colliding with enzyme molecules, so more product will be formed.
