Hypothesis: If i increase the amount of stirs then the salt will dissolve faster
Independent: variable the amount of times you stir the liquid or rate at which you stir the liquid
dependent variable: the rate at which the salt dissolves
Materials: beaker, water, salt, and stir rod
Explanation:
Endotherms use metabolic heat to keep a stable body temperature, while ectotherms do not. ... Metabolic rate varies with activity level. More active animals have a higher metabolic rate than less active animals. Some animals enter a state of torpor in which their metabolism slows.
Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement
The best and most correct answer among the choices provided by your question is the first choice.
The best analogy would be: the body storing energy is like a car holding gas: the car's gas tank keeps the gas until it is needed.
I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!
the Speed = Wavelength*Frequency. For example 22*5 = 110 which means the answer would be S = 110mm/s.
Are you sure this question is correct?
If you made a mistake and the question is 20mm/s and 5 freq instead of 22 and 5. Then your answer would be A. 100 mm/s.
Hope this helps! Please mark as brainliest if it did.
