Plant cells have a rectangular shape and a cell wall, while animal cells have a circular shape and no cell wall
1. homeostasis
2. negative feedback loop
3. the hypothalamus
4. the body’s optimal temperature, which is 37 degrees C, or 98.6 F
5. humans are endothermic, which means they don’t completely rely on their environment for heat, unlike ectothermic organisms such as reptiles. the diagram shows that the brain is in control of the body’s temperature, and that the body can raise its own temperature in its blood.
or something like that, hope this helped
Diverging plate boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates. We almost never see these volcanoes, because most of them are located on the sea floor.
