The answer is D. <span>Conclusions are drawn.
This is the only choice that can be done after data gathering, formulation, and analysis.
Other choices are in correct
</span><span>A. Controls and variables are chosen. (Identified before an experiment)
B. The initial experiment is designed. (Has been planned before an experiment is done.)
C. The initial hypothesis is formed. (Before the experiment a hypothesis is already drawn.</span>
The answer would be: It would have no effect, because tyrosine is also available from the diet
The pathway is different, alkaptonuria increased tyrosine is caused by decreased usage. In phenylketonuria, it is caused by increased production. While tyrosine is increased in phenylketonuria patient, it won't cause alkaptonuria because tyrosine could be found in the diet.
<span>In both cases money is being taken away from her total amount. A negative negative is a positive, so you don't want any expression with a negative negative. This eliminates A, B, and D, leaving only C. In this expression, both times money is being taken away, making it correct.</span>
Nucleic acids<span> are long polymers of repeating </span>subunits<span> called nucleotides. Each nucleotide is made </span>up<span> of three smaller building blocks (Figure 17): Figure 17 The structure of a nucleotide and the formation of </span>nucleic acid<span> chains.</span>
