The measurements taken by Jay are least likely to contain random errors.
When you increase the number of measurements, the random errors tend to minimize, because errors in one direction cancel with errors in the opposed direction.

Explanation:
Rôche moutonnée (or sheepback) could be a rock formation created by the passing of an ice mass. The passage of ice mass ice underlying bedrock usually leads to uneven erosional forms as a result of abrasion on the "stoss" (upstream) facet<span> of the rock and plucking on the "lee".

The TYR, TRP2, and TRP1 genes are located next to each other on a single chromosome and are organized into an operon is most likely to be accurate.
The option a is correct.
Explanation:
The genes for the Tyrosinase, TRP2 and TRP1 are located on the same chromosome and are operons. These are operons because they are controlled by same transcription factors on mRNA.
Tyrosinase enzyme is important for the synthesis of melanin, eye pigments and hair colour. The synthesis of all these is completed in three distinct reactions catalysed by TRP1, TRP2 and Tyr genes. These work as operon and the protein product is almost 40% similar of the three genes.
The amount of melanin production depends on tyrosinase enzyme activity of all the three genes.
The genetic regulation is done by operons.
