The rotation of the Earth in its axis
Answer:
In this case, the scientist want to test the presence of the limonite in the yellow rocks, So, proposed hypothesis should include the color of rock they want to observe and the posssible outcome, which need to be tested. So, a proposed hypothesis can be: The rocks, which have yellow color are made up of mineral lime.
May I see the answer choices? If so, then I can help. :)
1. Respiration-process by which plants release CO, while they break down the sugar
2. Animals eat plants- They break down sugars and starches by a process of metabolism and the products are energy water, and CO2 molecules.
3. Decomposition-when plants die, their parts (wood, leaves) decay bringing the carbon into the ground
4. Root respiration- respiration that occurs in roots, adds to soil respiration (the amount of CO2 produced through root respiration is determined by the root biomass ).
Carbon dioxide and water 6CO2 + 6H2O
