<span>Polypeptide
</span><span>
When Polypeptides join together, they form protein. The term Polypeptide chain is used to define the combination of Polypeptides. They are joined together by the peptide bonds. These Polypeptides are chains of amino acids. When one or more Polypeptide chains joined together, that is the time when Protein was born. As we all know, protein is very essential to our body. Because protein helps our body to function well. Protein makes our cells function properly. Can you imagine our body without protein? Thanks to Polypeptides chains that are joined together to form Protein so our body can function well. </span>
Answer:
Positive natural selection.
Explanation:
The positive natural selection is a type of natural selection that increases the frequency of an allele or trait when it is advantageous for the population. What happened in the example is that the mouth with the slight change in morphology (trait) was more advantageous for the population in the south in relation to the ancestral morphology (still preserved in the population in the north), and therefore its frequency increased. This, in turn, is due to the fact that the food (prey) is not the same in the two habitats (north and south). The specific prey in the south, caused the new morphology to be selected, (increasing the frequency of individuals with the new mouth), becasue probably that trait allows the trouts in the south to hunt more effectively.
Answer:
The correct answer is rRNA plays an important role during translation (protein synthesis) of mRNA.
Explanation:
Ribosomal RNA or rRNA are the RNA molecules which build up the site for protein synthesis known as ribosomes.
Ribosome synthesis takes place in nucleolus where two types of rRNA molecules associates with proteins, one in large subunit and one in the small subunit to form ribosomes.
These ribosomes physically moves along an mRNA molecule and catalyze the assembly of amino acids where rRNA molecules performs the catalytic steps of protein synthesis that is stitches amino acids together and makes up proteins.
Thus, rRNA plays an important role during translation (protein synthesis) of mRNA.
Answer: Lettuce
Explanation:
Lettuce is a plant, therefore it makes its own food through photosynthesis. Since it does this, we call it a producer or an autotroph.
