In an ecosystem, two factors are being classified which are the abiotic and the biotic factors. Both of these factors play an important role in order to balance the ecosystem and maintain the harmony of the living things therein. The environment includes the abiotic factors which are the sunlight, weather, water, air, and all other factors which are not living but contribute to the growth and development of the living ones. For example, plants cannot live without water, sunlight and carbon dioxide. The effects that humans have on the environment is both good and bad. Humans also play an important role in maintaining the environment, and they also have the capability to endanger it.
Anaphase is one of the stages that takes place during cell division either mitotic or meiotic. Anaphase in mitosis and meiosis II involves the separation of the two sister chromatids at the centromere and then the each migrates to opposite ends of the pole which is aided by the spindle assembly. Anaphase in meiosis I involves the separation of a pair of homologous chromosomes to opposite ends of the poles.
