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 correct answer for the fill in the blank is Asexually.
Asexually reproducing organisms have rapid rate of reproduction as only a single parent is involved in this. Also, there is no formation and fusion of gametes in this mode of reproduction.
They produce larger number of offsprings through rapid rate of reproduction. By doing so they have larger chances of survival.
For instance, if a part of bacterial species population is wiped out through viral infection, bacteria can compensate this loss by the rapid rate of reproduction. This increases their chances of survival.
Explanation:
Species of rats are found throughout the order Rodentia, but stereotypical rats are found in the genus Rattus. Other rat genera include Neotoma (pack rats), Bandicota (bandicoot rats) and Dipodomys (kangaroo rats). Rats are typically distinguished from mice by their size.
This is extremely vague, but assuming this is regarding concentration gradient in the nervous system, the Sodium-Potassium pump is responsible for transporting sodium and potassium.
