Answer:
Energy does not cycle the way nutrients and atoms do. Energy enters the ecosystem from the Sun and exits after the organisms have taken as much as they need. Organisms release energy back into the biosphere as heat.
The microscope made the discovery of cells possible
<u>Answer:</u>
The typical state of a neuron is the<u> resting potential</u>, but when electrical signals stimulate it to its threshold, the <u>action potential</u> is immediately observed.
<u>Explanation:</u>
The capacity for rest shows what occurs when a neuron is at rest. A capacity for action takes place when a neuron passes information down an axon, far from the cell body. When depolarization exceeds approximately -55 mV a neuron can activate the capacity for action.
Sodium-potassium valves start moving two potassium ions within the cell as three sodium ions are poured out to keep the negatively charged membrane within the cell; this keeps the resting potential in place.
Answer:
Lack of ability to adapt to changes in the envrionment
Explanation:
Asexual reproduction produces offspring that are genetically identical to the parent and no DNA is mixed, so they would not be able to adapt because there would be no genetic variation.
