Matter must have two physical properties: 1. have mass, and select all that apply. must move take up space be measureable use energy

Explanation:

Matter is defined as a substance that has mass and take up space as a matter also has volume.

For example, a wooden box is a matter.

Matter exists in solid, liquid and gaseous state. When an external force is applied then matter moves from its initial place.  Whereas we can measure the volume or mass of a matter.

Therefore, we can conclude that matter must have two physical properties: 1. have mass, and 2. take up space and be measurable.

surface mining destroys mountain tops, landscapes, forests and wildlife habitats. on top of that, it leads to soil erosion and destruction of agricultural land. the landscape changes can also disrupt river channels and streams, which leads to flooding. which, can destroy plant life and other animals as well.

explanation:

the answer that best describes the relative refractory period in the neuron is the resting membrane potential is restored, but concentrations of sodium and potassium are not restored to their original state.

the refractory period is the time during which another stimulus given to the neuron will not lead to a second potential. thus, because na+ channels are inactivated during this time, additional depolarizing stimuli do not lead to new action potentials.
