1) False. Scientists may predict something but realize a difference soon after before the test, so they could definitely change the hypothesis if they want. It’s only AFTER the experiment they cannot. Because a hypothesis is like a “guess” as to what’s going to happen, right?
2) False. A hypothesis can’t be “valid” because it’s literally a prediction.
3) True. Especially if you’re doing a chemistry lab, it’s really important things are done in order or else the product might result as something else you were expecting, or can be very dANGEROUS
4) True. The conclusion must be based on data because it’s the observation that was seen.
Hope this helps!! I could have answered in short form but I just wanted to make them understandable:)

Answer:
the glutamate causes an influx of ca2+ions the nerve cell akin to what occurs during depolarization.
Answer:
b. Yes, the average efficiency is 10%
Explanation:
The average efficiency at each trophic level is 10% because there is about 10% of energy is transferred from one trophic level to another. In some trophic levels the efficiency of organisms is 20% but in most of the trophic level has 10% efficiency so that's why the average efficiency is 10%. Yes, this ecosystem obeys the Lindeman's Law for ecological efficiency due to its 10% of ecological efficiency.
