Explanation:
Answer:
Mutation.
Explanation:
All adaptations begin as a genetic mutation because these adaptations passed from one generation to another generation through genes of that organisms. Organisms that are adapted to their environments and survive more better, it will produce more offspring in which that genetic characteristics are transmitted from the parents so we can say that genetic mutation is responsible for adaptations.
Answer:
FIRST ONE
Explanation:
Reproduction. Pink salmon in their native range have a strict two year life cycle, thus odd and even-year populations do not interbreed. In the state of Washington, Pink salmon runs occur on odd years. Adult pink salmon enter spawning streams from the ocean, usually returning to the stream where they originated.
Explanation:
Central dogma represents the pathway in which the information encoded in the DNA flows into proteins.
The DNA is made up of the nucleotide monomers in which the nitrogenous bases are present as one of the constituents. These bases are present in the sequence are transcribed into the RNA molecule through the process of transcription.
The nitrogenous sequences in this RNA molecule are then translated into the proteins through the process of translation during which the sequence is read in pairs of three called "codons". A specific amino acid is attached to the peptide when the codons are read by the translation machinery and a protein is formed.
These proteins could perform various roles in organisms from physical to biochemical and thus the physical traits are controlled by the DNA.
