The nitrogenous bases placed in between the DNA double helix strands, like rungs on a ladder, are positioned there because of the hydrophobic effect and are stabilized by hydrogen bonding. The stability of DNA also relies on the interactions between the hydrogen bonds between bases, hydrogen bonds between bases and surrounding water, and base interaction between neighboring bases.
Hydrogen bonds are able to stabilize the DNA double helix by pairing up with their complementary base pairs (guanine with cytosine and adenine with thymine)

We can confirm that Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed vestigial.
<h3>What are vestigial features?</h3>
These can be thought of as features that belonged to ancestors of a specific species and are no longer needed, and thus have been reduced to functionless vestiges through many generations of evolution. The appendix is one such example in humans.
Therefore, we can confirm that Anatomical features that are fully developed and functional in one group of organisms but reduced and functionless in a similar group are termed vestigial.

Answer and Explanation:
The sympathetic nervous system prepares the body for vigorous physical activity and is often referred to as the fight-or-flight. The parasympathetic nervous system relaxes the body and inhibits many high energy functions and is often referred to as rest and digest. Parasympathetic system is one of several excitatory pathways during arousal. The excitatory signals can originate in the brain, either by the sight or thought of an appealing sexual partner. Arousal is an example of parasympathetic system.
During flight and fight, the liver can be stimulated to release glucose into the bloodstream providing more energy that will be ready to power the muscles.
