Help as soon is possible (ONE YOUR OWN WORDS) I will mark Brainliest TO THE CORRECT ONE! A major oil spill happened 20 years ago in the Antarctic Ocean. Since then, scientists have been studying its effects on the food chains in this area, like the ones shown in the figure. What prediction can be made about how the presence of the oil spill continues to affect the animals shown in the web? Compare the effects now with those expected 20 years later and be sure to include specific examples of the impact on the different trophic levels.

prophase: we can observe the chromosomes to coil up and condense. they become visible. nuclear membrane and envelope disintigrate.s

metaphase: chromosomes align at the center, the metaphase plate. spindle fibers attach to centromeres of the sister chromatids. they meet at kinetochores.

anaphase: sister chromatids are pulled towards each opposing centromere, set on different poles.

telophase: chromosomes are now clustered up only on either sides of the cell. nuclear membranes reform, and a new cell wall forms along the cell plate. this will lead to cytokinesis, the process that divides the cell membrane and forms the cell wall.

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
