Mitotic spindle formation depends on the capturing of microtubules at kinetochores. During prophase phase of the cell division, spindle fibers emerge from the centrosomes after nuclear envelope breaks down and nucleolus disappears
In the Prometaphase, kinetochores appear at the centromeres on one hand and on the other hand chromosomes continue to condense and mitotic spindle microtubules attach to kinetochores
Hence, it is true
Answer: In the lab activity, I used a virtual watershed to demonstrate how pollutants enter and flow through the watershed. I constructed food chains to show how biotic factors are related. I also predicted and modeled how human activity affected the biotic factors in an ecosystem. Based on my observations, I can conclude that biotic and abiotic factors are closely linked and that human activity that changes the environment, like pollution, can affect all the other parts of an ecosystem in a negative way.
