Answer:
Biotic factor
Explanation:
Competition only exist due to limited resources (abiotic factors AKA environment) which occurs in biotic factors (living organisms).
Fear factor is nonsense because fear does not exist in plants but they still compete for sunlight and water.
Factory factor is nonsense as well because this term does not exist in biology.
Answer:
The answer to your question is pH = 9.08
Explanation:
Data
pH = ?
Concentration = 1.2 x 10⁻⁵ M
Process
1.- Calculate the pOH of the solution
Formula
pOH = -log[OH⁻]
pOH = -log[1.2 x 10⁻⁵]
pOH = 4.92
2.- Calculate the pH
Formula
pH = 14 - pOH
Substitution
pH = 14 - 4.92
Result
pH = 9.08
Answer:
Independent variables are ones that can be controlled and dependent variables are results of these changes. So, in question a, an independent variable is amount of a released energy, in these case in form of heat. We reduced that amount and as a result we get a dependent variable as high temperature of chocolate for longer time, so we changed time of a heat releasing from chocolate. In question b, an independent variable is temperature of water, and a dependent variable is amount of produced oxygen. In question c, an independent variable is an intensity of exercise. When we change the intensity of exercise, as a results, breathing rate is changed, which is dependent variable.
