Explanation:
Luis was most trying to model the Earth's rotation. As you know the earth rotates around it's axis once every 24 hours and this is why we have different times in the day because the sun shines on different parts of the Earth as it rotates.
Luis used the flashlight as the sun and when he used the toothpick to spin the model of earth, the model would represent earth rotating around its axis.

The main purpose of seeds is to carry out reproduction so that the plants can perpetuate themselves. After pollination and Fertilization the seed formed has the capacity to germinate into an adult plant over time. It has all the necessary nutrients and food sources required for a plant to germinate and are also modified for different species to allow for further dispersal so the plant can spread more easily to better growth conditions.
Answer: A microscope is an instrument that produces a clear magnified image of an object viewed through it. A microscope must be able not only to magnify objects sufficiently but also to resolve, or separate, the fine details of the object that are of interest to the viewer. In the optical microscope visible light rays, reflected from or transmitted by the viewed object, pass through a series of lenses and form an enlarged image of the object. This image is produced at the normal distance of clearest vision, which is about 10 inches, or 25 centimetres, from the eye of the viewer.
