The two main points from Darwin's theory of evolution is that 1) most, if not all living organisms evolved from one or just a few common ancestors and that subsequent specialization of further generations then led to new species. Furthermore, he said that 2) the process how this was done was by natural selection where the organisms which were most adapted to their environment were successfully 'remembered in the gene pool'.

A mutation in _____ results in a change in _____ that sometimes produces a(n) _____ with altered structure and function.

xenn [34]

Answer:

A mutation in DNA results in a change in RNA that sometimes produces a protein with altered structure and function.

Explanation:

DNA is the hereditary material which causes gene expression in our body by producing protein. The type of protein which is produced by DNA totally depends upon the sequence of nucleotides in the DNA. But, DNA molecule does not produce protein directly. Initially it produces RNA (mRNA, tRNA, rRNA) by the process of transcription, the nucleotides in the RNA are complimentary to those in DNA. In short, the message regarding the structure and composition of the type protein to be produced by DNA is first decoded from DNA in the form of RNA. These RNA molecules then synthesize the protein as per the instructions from DNA by the process of translation.

But, in case a mutation occurs in the DNA which causes a change in it's nucleotide/nucleotides, the protein which will be produced will be different in the structure and function than the protein which was supposed to be synthesized. It happens because, a triplet of nucletiodes in the DNA and hence RNA specifies a particular type of amino acid and several amino acids are joined in a long chain to form polypeptide which ultimately forms protein. But, if any nucleotide in the triplet is changed due to mutation it may change the amino acid and if amino acid will change the protein will also get altered.

Would the left or right ventricles of the pig heart have more cardiac muscle? explain.

I am pretty sure a pigs heart has the same structure as a human heart so in saying this the if i remove correctly the right side has more muscle as it has to provide blood to most of the body not including the lungs
