Jack is using an OPTICAL MICROSCOPE. This type of microscope uses a light that is visible in order to magnify the samples sharply. The optical lenses refract the lenses which means that light is set to an angle as it bounces through the glass lens. There are actually three types of optical microscopes: The compound microscope which is built with dual lenses and bigger magnification, stereo microscope which provide a view of the specimen that is 3D, and confocal laser scanning microscope that is so advanced that it can delve into observing the specimen in detail, and often with the help of computer <span> </span>
The correct answer is - D) covered by warm shallow seas.
The fact that the crinoids are have an abundance in the fossil records in Pennsylvania in the Mississippian Period, tells us that this area was covered with shallow and warm seas. The reason why we can get that conclusion is that the crinoids live only in that kind of environment, so it simply a logical conclusion.
The geological data is also confirming this, as it is easily noticeable in the layers that during this period of the geologic past, what is now Pennsylvania, was covered with shallow sea waters. Also, this waters were warm too, as the climate was warm and humid and that period, so it was a perfect environment for the crinoids to flourish.
The leaders of the earliest philosophers were Socrates and Aristotle. This led the thinkers who arrived at the conclusion regarding the Primary Entity.
<h3>
What was the proof for the conclusion of the Primary Entity?</h3>
Their logic for arriving at the above conclusion that "the primary entity (arche) always persists)" was that, since nothing can be completely annihilated or truly generated from the origin, but each returns to it's origin if they are destroyed, then it means that the primary entity must always persist.
In simple language, nothing is either destroyed or created.
