C. experimental
Explanation:
Experimental variables are the variables that are changed during the experiments to observe the effects of these changes. An experiment usually has one or more experimental variables. An experimental variable that is changed to know its impact on some other variable is called the independent variable.
In the given experiment, goldfishes were exposed to various temperature conditions to observe the effect of temperature on respiration. Therefore, both temperature and respiration rate are the experimental variables here.
Answer:
9 amino acids
Explanation:
A segment of a gene that has 27 nucleotides will code for<u> 9 amino acids.</u>
<em>Each codon on the gene potentially represents an amino acid and a codon is made up of 3 nucleotides each. Hence, in order to find out the total number of amino acids that a gene segment with 27 nucleotides can code for, the number of nucleotides should be divided by 3.</em>
number of amino acids = number of nucleotides/3
27/3 = 9 codons/amino acids
