Is Anthracite Coal manmade

No

Explanation:

"Anthracite coal forms when bituminous coal undergoes very low-grade metamorphism, accompanied by structural deformation. The fixed carbon content under these conditions reaches 85-95%. If anthracite is metamorphosed further it turns into graphite."

the ozone layer acts as a filter for the shorter wavelength and highly hazardous ultraviolet radiation (uvr) from the sun, protecting life on earth from its potentially harmful effects. when the sky is clear, there is an inverse relationship between stratospheric ozone and solar uvr measured at the earth's surface.

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
