What are the three major events that occur during each of the stages in the life cycle of a cell such as skin cell, interphase, , prophase, metaphase, anaphase, telophase and cytokinesis

IN interphase During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, reads its DNA, and conducts other "normal" cell functions.  in the skin cell On average a skin cycle is 5-6 weeks. At the age of 19-21,the process can take 14-21 days compared to a middle-aged adult where it is estimated to be 28 days. As we grow older, this skin cycle slows to about 45-60 days in our 40's and 50's. It can further slow to about 60-90 days in our 50's and 60's.  Prophase is the first phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. Metaphase is a stage in the cell cycle where all the genetic material is condensing into chromosomes. These chromosomes then become visible. During this stage, the nucleus disappears and the chromosomes appear in the cytoplasm of the cell. ... As metaphase continues, the cells partition into the two daughter cells. Anaphase is the fourth phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. During anaphase, each pair of chromosomes is separated into two identical, independent chromosomes.  During telophase, chromosomes arrive at opposite poles and unwind into thin strands of DNA, the spindle fibers disappear, and the nuclear membrane reappears. Cytokinesis is the actual splitting of the cell membrane; animal cells pinch apart, while plant cells form a cell plate that becomes the new cell wall. Cytokinesis is the final stage of cell division in eukaryotes as well as prokaryotes. During cytokinesis, the cytoplasm splits in two and the cell divides. ... In animal cells, the plasma membrane of the parent cell pinches inward along the cell's equator until two daughter cells form

Explanation:

poor water quality affects most estuarine organisms, including commercially important fish and shellfish. the pollutants that have the greatest impact on the health of estuaries include toxic substances like chemicals and heavy metals, nutrient pollution (or eutrophication), and pathogens such as bacteria or viruses.
