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.
Since all of the three beetle species posses the protein, we can use it to determine their relations. We can study the sequence of the amino acids that make the protein and the 3D structure of the protein. The more differences there are in amino acid sequences and the structure of the protein, the species are more distantly related because they have diverged a long time ago and their genes that produce that protein have undergone many changes over time.
3. Mechanical energy is the energy used by organisms to function and move.
3. The conservation of energy is the process in which organisms use up the energy in a cycle where nothing is wasted.
I would believe the correct responses would be option 1,2,4.
