Vertebrates developed about 550 million years ago. The oldest vertebrate fossils are those of FISH with no jaws. These e<span>arly jawless fish did not have paired fins and their bodies were covered with heavy, bony scaled, but their skeletons were made of cartilage. For the next 50 million years, they were the only vertebrates.</span>
There's a great picture that I attached below that is a great representation
The nucleus would be like the command center in the cell, because it monitors the cells functions and keeps everything "running smoothly".
Electromagnetic waves are waves propagated by simultaneous periodic variations of electric and magnetic field intensity that include radio waves, infrared, visible light, ultraviolet, X-rays and gamma rays.
Damped oscillation means that there is some force that causes the oscillation to become smaller and smaller over time. For example, the pendulum exhibits an oscillation motion. Over time, the swinging of pendulum would come to a stop, unless a force is acted on it.
Forced oscillation means that an outside force causes an object to oscillate at a certain frequency. For instance, if you decide to swing the pendulum so that it won't stop from swinging, the action is called forced oscillation.
On the other hand, resonance oscillation refers to the increase in an amplitude of oscillation of an electric or mechanical system exposed to a periodic force whose frequency is equal or very close to the natural undamped frequency of the system.
Among the three types of oscillation, resonance is most likely to produce an electromagnetic wave.

no
