Answer:
The most likely explanation for the truncated polypeptide -due to the substitution of cytosine for adenine- is that mutation introduced a stop codon in the middle of the gene.
Explanation:
A codon consists of three nucleotides -in the RNA chain- whose order determines a specific amino acid. Not all codons code for amino acids, as there are termination codons, also called stop codons, which are UAG, UGA and UAA.
If in Manny's computer model, the substitution of cytosine by adenine produced a termination codon, the synthesis of a peptide is stopped prematurely resulting in a truncated peptide.

Reverse Osmosis.
Explanation:
This is the mechanisms of water purification for drinking water which is droven by the chenical potential of the solvent .
It involves the use of partiaiy permeable membrane to allow ions , water molecules ,solvent molecules to pass through during purification
A pertial permiable menenrane in this prurifiction process is the membrane that allow only water molecules, ions and restricted other unwanted chemical contaminants from passing through it.
The Pezizales are an order of the subphylum Pezizomycotina within the phylum Ascomycota.

Explanation:
Immunity to a disease is achieved through the presence of antibodies to that disease in a person's system. Antibodies are proteins produced by the body to neutralize or destroy toxins or disease-carrying organisms. Antibodies are disease-specific. Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system's antibodies and other cells to target the invader. A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response.
These molecules are called antigens, and they are present on all viruses and bacteria.
