Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA.
Answer: This modern-day researcher used some of the same theories that Darwin proposed. Like Darwin and his finches and tortoises, this scientist understood that the Galapagos cormorants inherited flightless wings.

This evolution was similar to how the flightless Galapagos cormorants evolved from other species of cormorants.
Explanation:
The right ventricle pumps deoxygenated blood to the lungs.
Mutations acquired by somatic cells are generally only retained by the individual they acquire in as there is no vector by which to transmit the mutation.
<span>Between generations, the only mutations that may be transmitted are those already acquired from a parent, and those that occur within the individuals own germ cells. If mutations in the germ cells result in sperm or eggs that contain that mutation, then they may be transmitted to their offspring. </span>
<span>Red blood cells in all humans and other mammals, though, don't contain nuclear DNA and as such cannot acquire mutations.</span>
In the absence of oxygen, fermentation releases energy from food molecules by producing ATP.
Explanation: By fermentation releasing food molecules it allows for ATP to begin.
