At a county fair, Tom enters a haunted house with his friends. As soon as he steps inside, his heart rate and breath rate increase. When a costumed character jumps out at him, Tom jumps. When the costume character retreats, Tom runs out of
the haunted house.

Draw a flowchart that explains how Tom's nervous system controls his actions. As part of the flowchart, write one or two
sentences describing how the rervous system is involved in each of these steps:
1. Tom steps into the haunted house.
2. Tom feels his heart pumping and his breathing speed up.
3. Tom jumps when he sees the costumed character.
4. Tom runs out of the haunted house

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.

the answer is b)3/8x+1
