The idea needs to be tested for it to be scientifically reliable. First, a hypothesis has to be drawn up. A simple explanation for the word "hypothesis" is an educated guess. The scientist makes an educated guess in answer to a problem. He then sets about proving or disproving the hypothesis. This is done by setting up related scientific experiments. <span>For the theory to be scientifically proved, the experiments need to be set up in such a way that the results are measurable. </span>
The benefits of the endangered species act are
-Helps most at risk plants and animals regulate population, and hopes to eventually move these plants, as well as animals from the endangered species list.
-It's proven to have helped over 99 species recover and start going steady again, for example Gray Wolves, People hunted them in the Southern States, Until most of them we're towards a couple of states in the North. Until they we're reintroduced in the 1980's, Since then the wolf population has thrived and now has over 5,000+ across the United States.

Answer:
Because of the natural selection
Explanation:
Variation in nature is all we can found out there. Through millions of years nature went with the survival of the fittests, like Darwin said.
When we talk about artificial selection, we talk about humans getting involve on that selection, but we deppend on variation in nature. We can't "create" a new species, but we do can choose the genetic traits we want to prosper and which no.
Answer:The inward flow of sodium ions increases the concentration of positively charged cations in the cell and causes depolarization, where the potential of the cell is higher than the cell's resting potential.
