i believe it would be the last one "screens remove solid debris, grits and sand"
Explanation:
Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.

Explanation:
Answer:
1. The difference in charge across the membrane is called the - membrane potential.
2. It is measured in mV
3. At resting potential, the charge of the outside of the neuron is 70 mV less negative than the inside
4. Once a stimulus changes the membrane potential, the neuron conducts an impulse called a(n) Action Potential
5. This causes the charge outside the cell to temporarily become positive and the inside to temporarily become negative
6. When the action potential arrives at the axon terminal it reaches a junction called the Chemical Synapse
