Answer:
d. if my hypothesis is correct, I can expect certain test results
Explanation:
To create a theory is not enough to state an assumption. Called scientific research, the practice tries, through a logical procedure, to produce tested, proven and safe scientific knowledge. This concept is based on the logic of scientific research that states that a hypothesis must be tested, because if the hypothesis is correct, certain test results can be expected. For this, some rules or phases are part of the process. And they are: observation, hypotheses, research method and conclusion.
Thus, we can conclude that among the alternatives presented, the one that best describes the logic of scientific investigation is the letter D.

Answer:
The correct answer is - Similar nucleotides are present in both fruit-fly and frog DNA.
Explanation:
Fruit fly or drosophila DNA sequence and DNA sequence of the gene of frog for a particular trait is combined and heated to separate the DNA strands by separating the nucleotides present between the strands of both organisms.
This is observed after cooling down the single strands after paired up that some of the DNA paired with the DNA. This is only possible if the DNA strands of the particular gene have similar nucleotides to form hydrogen bond in single strands of DNA of frog and fruit-fly.
