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:)
Explanation:
ATP is the short form of Adenosine Triphosphate. The molecule is made up of three basic things:
- Adenine ring
- Ribose sugar
- Three phosphate groups(triphosphate)
This molecule is provides the energy needed for life processes when broken down.
The elements that makes up ATP are:
- Carbon(C)
- Hydrogen(H)
- Nitrogen(N)
- Oxygen(O)
- Phosphorus(P)

Answer: Minerals
Explanation: The body decomposes and after about 40 to 50 years bones are mostly brittle and dry with no traces of flesh. After thousands of years bones also disintegrate (decay) leaving brittle mineral frame. The life of bones is determined by the soil type its buried in, nuetral soils takes longer then acidic soil condition.
In this case osteocytes(bone cells) are the first to decompose followed by the cartilage and bone marrow, leaving behind mineral traces that scientist can study after thousand years.
