Answer: Covalent bonds form when atoms share their valence electrons with other atoms to become a more stable molecule.
Explanation: Atoms form covalent bonds as a result of the Octet Rule. The Octet Rule states that all atoms in a molecule need to have eight electrons in their valence shell. This rule can be satisfied by sharing, losing or gaining electrons. A covalent bond allows atoms to satisfy the Octet Rule via sharing.
The last type of symmetry is the bilateral symmetry. Bilateral symmetry is when the body plan can be divided along a plane that splits the animal's body into right and left sides that are mirror images of each other. Let's look at this type of symmetry a little more.
<span>The autonomic nervous system
The autonomic nervous system (ANS) is the part of the peripheral nervous system that acts as a control system, functioning largely below the level of consciousness and controlling visceral functions. The ANS affects heart rate, digestion, respiratory rate, salivation, perspiration, pupillary dilation, micturition (urination), and sexual arousal. The ANS is classically divided into two subsystems: the parasympathetic nervous system (PSNS) and sympathetic nervous system (SNS).</span>
