Please help me I will give you the brain thing and extra points. image below part 3

Explanation:

Baking soda (NaHCO₃) and acetic acid (C₂H₄O₂) in vinegar react.

They form water (H₂O), sodium acetate (NaC₂H₃O₂), and carbon dioxide (CO₂).

This must be a chemical change, because new products are formed. We can eliminate choices B and C, because they are physical changes. Physical changes don't require a chemical composition change.

So, we are left with choices A and D.

Choice D must be incorrect because mass cannot disappear. According to the Law of Conservation of Mass, mass can't be made or destroyed.

That leaves choice A. Combining baking soda and vinegar is a chemical change, because new products, like gas, are formed. The gas helps blow up the balloon.

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.
