Chemical weathering changes the composition of rocks, often transforming them when water interacts with minerals to create various chemical reactions. Chemical weathering is a gradual and ongoing process as the mineralogy of the rock adjusts to the near surface environment.
Answer:
I believe that the protists were the first organisms on earth. And the other 5 kingdoms then came from the protists.
I think that's it! :)
Answer: There will be no effect on the protein produced
Explanation:
According to the genetic code, the triplet codon GAG code for the amino acid, glutamate, while GAC code for aspartate.
Since GAG and GAC code for amino acids with similar properties (aspartate and glutamate are both acidic amino acids due to the extra carboxyl group present in their side chain), the change in nucleotide is still similar to the original, so will result in a different amino acid sequence, but will not alter the function of the protein at all. Thus, this kind of mutation is called silent mutation.
