Pavia slips and falls in the bathroom and bangs her head on the tile floor. She begins to see "stars" and flashes of light, indicating some activation of brain cells in the . frontal lobe occipital lobe reticular formation parietal lobe

Explanation:

The occipetal lobe of brain is associated with the sense of vision. Any damage or activation of occipetal neurons will lead to disturbed visual effects.

Sometimes severe injury to this part may lead to vision loss or permanent blindness.

So we can conclude that Pavia started seeing stars and flashes of light as a result of activation of cells in the occipetal lobe.

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.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
