I believe proteins are synthesized from amino acids during synthesis reactions.
Protein synthesis starts with transcription of mRNA from a DNA gene in the nucleus.Various types of RNA may have been synthesized using the appropriate DNA. The RNAs migrate from the nucleus to the cytoplasm where the process of translation takes place. During the process the mRNA with the codons (three nucleotide bases that code for a specific amino acids) is interpreted by the anticodons in the tRNA , thus forming amino acids with together forms polypeptides and then proteins are formed.
Morphological changes to function appendages arise because of different requirements this was termed by Darwin as adaptive radiation. For example darwins finches - each birds beak was slightly different in shape - this allowed them to exploit a different food source, thereby reducing intra specific competition. As for fins, these vary depending on the swimming requirements of the organism; balance, agility or speed may be selected for.
The correct answer is option A, that is, theories.
A restricted explanation of a phenomenon is referred to as a hypothesis. A statement regarding an observed phenomenon or a unifying concept is considered as a law. A law differs from a scientific theory in that they do not postulate an explanation or mechanism of the phenomenon, they are just a filtration of the outcomes of recurrent observation.
However, a scientific theory refers to a thorough explanation of the observed phenomenon.
well biological could be your well mainly your looks how tall how short think physical sameness
the motive could be like smoking you think its cool cause your parent do it maybe
