Answer: Fluorescence microscope

Explanation:

The basic function of a fluorescence microscope is to irradiate the specimen with a desired and specific band of wavelengths. A fluorescence microscope uses a mercury or xenon lamp to produce ultraviolet light. The light comes into the microscope and hits a dichroic mirror. The dichroic mirror reflects the ultraviolet light up to the specimen. The ultraviolet light excites fluorescence within molecules in the specimen. The objective lens collects the fluorescent-wavelength light produced. This fluorescent light passes through the dichroic mirror and a barrier filter, making it to the eyepiece to form the image.

How does the size of the moon’s core support the impact of the moon’s formation?
kogti [31]
The span of the moons center has nothing to do with the effect hypothesis, however has a remark with materials on the moon itself.
Since this hypothesis itself did not merged with regards to the arrangement for the lunar center however it emerged as a result of the materials that make up the moon itself in light of the fact that the materials that make up the moon contrasted with our own particular planet looks like an enormous similitude.


Or the answer will be:

If the event that effect the hypothesis is r8ght at that point after the impact material from the surface and mantle of the earth was brushed off into space gathering into the moon. There would be next to no material to shape a gigantic center.

Suppose molecules were unable to diffuse into and out of the cells. How might life be different if cells had to use active trans
antiseptic1488 [7]

Answer:

Cells would most probably not exist because these units of life metabolize energy molecules like glucose to harness their energy for the running of biochemical processes, like active transport, to support life. However, harnessing this energy from these energy molecules is NOT 100 percent efficient. A higher percentage of energy is lost as heat in the process.

Therefore if the cells were required to carry all molecules in and out of the cell, actively, including the energy molecules themselves (which is counterintuitive), this would require a lot of energy and would be unsustainable. This would be analogical to the counteracting and infinite loop of more fuel needed to carry the mass of the more fuel in space travel...
