Answer:
codons
each codon encrypts a specific amino acid
Explanation:
Answer:
Mutation, Gene flow/Migration/Immigration of gene and Recombination
Explanation:
For any species there are majorly three sources of genetic variations –
a) Mutation – This leads to change in the genetic code with in the DNA of an organism. Sometimes mutation does not produce any effect on the organism. Mutation can produce both positive and negative impact. Its effect is observed in long run as its rate is slow.
b) Recombination – When an organism undergoes sex, his/her genes recombine with the genes of mating partner. The rate of recombination is faster than the rate of mutation
c) Gene flow /Migration/Immigration of gene – In this gene travel from one set of population to the other. The frequency of gene in the mixed population lies between the original population gene frequency and the migrated or donor population gene frequency

Each group of three nucleotides encodes one amino acid. Since there are 64 combinations of 4 nucleotides taken three at a time there are 20 amino acids.
Answer:
The correct answer is - reducing competition between the birds for resources.
Explanation:
In this ecosystem, the two species of birds brown creepers and nuthatches share habitat in the same tree for their food resources are insects. Brown creepers feed on resources on the bottom of the tree whereas nuthatches feed on the top of the tree.
By this, they avoid competition between these two birds for the same food resources in the same tree. The competition would be more if both have depended on the insects all over the tree.
