One example of how natural selection can change the distribution of a trait is the peppered moths during the industrial revolution. The moths were originally mainly white with a few black spots, however, when all the factories were built, the trees the peppered moths lived on turned a black color, causing ones who were mostly white to be picked off by predators, but the ones that were black with a few white spots survived and blended in better, leaving them to breed and produce more black-colored moths that would survive easily. This shows the changing of a trait because ones that used to be mostly white were killed, showing a shift in the trait pattern in favor to the black moths that now lived instead of the white moths.

Answer:
mRNA: AUG CAA AAU GCG AUC UGA
Amino acids: Methionine, Glutamine, Asparagine, Arginine, Isoleucine, Stop
Explanation: for amino acids just make the usual pairs, so G-C and T-A but T is U in mRNA. For the amino acids, just read off the table starting with the first letter of the triplet in the centre then reading outwards for the second and third.
Hope this helped :)
Answer:
adenine (A), cytosine (C), guanine (G), and thymine (T)
Answer: The advantages of spines in these unrelated organisms are as follows:
- for escape and defence
- for regulations of body temperature
- for conservation of water
Explanation:
The evolution of spines in Tenrecs, echidnas and hedgehogs represent STRUCTURAL ADAPTATION i.e when a part of the body of a living organism undergoes changes to become structurally adapted to its mode of life.
- The evolved spines in hedgehogs are for physical defence
- in tenrecs, they are for physical defense
