D. controlled
An experiment in which only one variable is changed is a controlled experiment.
Explanation;
-A control experiment is an experiment where the researcher only changes one variable at a time in order to isolate the results.
In a controlled experiment, most conditions are constrained so that they do not change. One or two other conditions are then changed and measured by the experimenter. These are known as the independent variables.
For example; An experiment where all subjects involved in the experiment are treated exactly the same except for one deviation.

See answer below
Explanation:
Hi there,
Assuming this DNA strand is fully capable of being mature mRNA (5' m7G cap and PolyA tail), nucleotides lead to an mRNA codon, which is 3 nucleotides per codon. In turn, 1 codon leads to 1 amino acid. However, as a single strand, it must be capable of terminating translation, which always requires a stop codon, and thus 3 nucleotides. Hence, we must subtract this from the total amount of codons <em>first</em>.
Hence, only 11 amino acids will be coded by a single DNA strand 36 ncltd long.

The eruption of Mount Saint Helens has proved to have dramatically change the abiotic and biotic factors of its environment. As what was shown in the image just 24 years from its eruption, we can already observe that animal life began to populate the region due to its sufficient vegetation.
