What is the carbon cycle? Why is it important? - Answer The carbon cycle is the mouvement of carbon between species, the earth, the atmosphere and oceans. Without carbon, ecosystems would not function and persist over time. Most exchanges involve the ocean. What are the crucial processes in the carbon cycle? Why are they important? - Answer Cellular respiration and photosynthesis. They cancel each other out so that there isn't too little CO2 (causing a frozen earth) or too much CO2 (causi...

A new species has been discovered and is said to have its own non pre-existing cells, unique from cells found from every existing Earth species. The species is not extraterrestrial, is this possible? No this is not possible because all cells have to come pre pre-existing cells. 2. Natural selection is the transition of genome material? T or F (genetic material) 3. A trait that allows a bird to grow a long heavy tail, is transferred to the next generation. I
