Answer:
convention cells
Explanation:
In the field of fluid dynamics, a convection cell is the phenomenon that occurs when density differences exist within a body of liquid or gas. These density differences result in rising and/or falling currents, which are the key characteristics of a convection cell. When a volume of fluid is heated, it expands and becomes less dense and thus more buoyant than the surrounding fluid. The colder, denser part of the fluid descends to settle below the warmer, less-dense fluid, and this causes the warmer fluid to rise. Such movement is called convection, and the moving body of liquid is referred to as a convection cell. This particular type of convection, where a horizontal layer of fluid is heated from below, is known as Rayleigh–Bénard convection. Convection usually requires a gravitational field, but in microgravity experiments, thermal convection has been observed without gravitational effects.
Answer:
stem
Explanation:
because the branch is connected to the tree and the branch has stems that have leaves on them
Lashley is looking at different ways in which the brain works, especially different parts of the brain. If part of the brain was damaged and you compare how well the rat completed the task before and after the damage, then you can determine what function that part of the brain does. Also, if you study how well the rat completes the task as time progress, you can see if the rat is able to use other parts of the brain to "learn" and repair the damaged part of the brain.
