YES.The distribution of bases in sea urchin DNA and salmon DNA follow Chargaff's rules because the percentage of A bases is approximately equal to the percentage of T bases, and also the percentage of G bases is approximately equals to the percentage of C bases in both species. According to Chargaff's rule the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine.
The effect of a catalyst is to increase the speed of the reaction, this is the speed at which reactants, A and B, are consumed, ant the product, C, is produced.
Given that when C is produced the solution bubbles, the bubbles are an indication of progression of the reaction.
The greater the speed of reaction, the earlier the reaction will end and the earlier the bubbles will stop.
So the student can identify the catalyst because the bubbles will stop first.
Answer: <span>The test tube that stops bubbling first contains the catalyst.</span>
It is known as a transgenic organism. This procedure is otherwise called "genetic engineering." Genes of one species can be altered, or qualities can be transplanted starting with one animal types then onto the next. Genetic engineering is made conceivable by recombinant DNA innovation. Living beings that have modified genomes are known as transgenic.
D because they are complete systems
