Check Your Understanding 1. A system consists of components of matter and energy and the processes that involve the matter and e
irina [24]

Here, matter is gas, rock, lava and water, energy is heat, light. While the process in a system is melting and motion.

<h3>What is matter?</h3>

Matter is any material that has a mass and occupies space by having volume in classical physics and general chemistry.

Energy is a physical system's ability to perform work. The uppercase letter E is a common symbol for energy.

The act of determining the best intercommunication of processing units, as well as the best type and design of units in a process system.

In the given scenario,

  • Mater: gas, rock, lava and water.
  • Energy: heat, and light.
  • Process of system: melting and motion.

Thus, this way the given scenario can be classified.

Sunny_sXe [5.5K]

Answer:

a vestigial structure

Explanation:

Vestigial structures are a rudimentary (or even functionless) version of a body part, but they have important functions in a closely correlated or evolutionarily close species, an example of which is the presence of eyes in fish of the genus Astyanax. The existence of these vestigial structures is strong evidence that evolution occurs in organisms, since this structure, today without much apparent function, may in the past have been extremely important to the ancestors of that species.

Describe how the action potential is regenerated by local ion flux
zhenek [66]
Action potential is a mechanism of transfer of ions across the plasma membrane down their elctrochemical gradient. Action potential is regenerated by the influx of ions such as sodium in case of voltage gated sodium channels. The voltage gated channels can be either open or closed depending on the action potential. Depolarization of membrane leads to the opening of these channels that allow the sodium ions to enter the cell down their electrochemical gradient. The threshold of action potential is reached when the entry of sodium ions out reach the exit of potassium ions from the cell. This leads to the generation of action potential.
