In the electron transport chain, protons are pumped from the <u>mitochondrial matrix to the intermembrane space</u>, and oxygen is reduced to form water.
The energy derived from the transfer of electrons through the electron transport chain is used to pump protons, as a result, an electrochemical gradient is generated, consisting of a proton gradient and a membrane potential.
The energy created by the formation of this gradient is then harnessed to form ATP as the protons travel down their gradient into the matrix through the ATP synthase channel.
The electron transport and ATP production occur simultaneously and are tightly coupled.

Answer:
The correct answer is -
the independent variable - if fertilizer added or not,
the dependant variable - the height of the plant and
the standardized variable - 200ml water
Explanation:
In this study, the student wanted to see the effect of the fertilizer on the growth of the plant so the independent variable is the treatment of the fertilizer as manipulated or the independent variable is the factor which is affected or changed purposely during an experiment while other variables remain constant.
The dependent variable is the factor that is based or depends on the independent variable and measured to see the effect which is the height of the plants in this case.
The standardized or the control variable is the variable that remains constant throughout the experiment, 200 ml water treatment is the control variable in this experiment.
Answer:
I believe the answer is
B. The biotic and abotic items in the ecosystem.
OR
A. All of the different population of species in one geographic area.
Explanation:
Biological community consisting of living organisms in different locations. For example, a forest trees and undergrowth plants, inhabited by animals and rooted in soil containing bacteria and fungi, constitutes a biological community.
An atmosphere is a layer of gas or layers of gases that envelope a planet, and is held in place by the gravity of the planetary body.
I believe the answer is A. this has to do with the law of conservation which states that nothing is either created or destroyed in a chemical reaction. so the mass of the reactants will be equal to the mass of the product
