What quantity does the gradient of a force against extension graph represent?

It is the force constant of the material in N/m. So you can substitute it into the equation F=kx (F=force, k=force constant or gradient in N/m, x = extension)
You would expect the extension to be on the y-axis normally since it is the measured value. However since you want to use the graph to calculate certain values it is on the x-axis (you can also find the work done by the force by finding the area under the graph)
Also it allows you to divide the y-axis values by the cross-sectional area and x-axis values by original length to get a stress vs strain graph where you can use the gradient to find the Young modulus of the material.

How can active transport differ from passive transport?
Active transport can occur against a diffusion gradient ("uphill flow).
Why active transport requires energy?
Active transportation is taken place against concentration gradient. So this requires energy .
Of friction is used to represent the degree to which two surfaces will resist sliding against one another.?
Coefficient~Apex:)
What is the energy given up by electrons as they move through the electron transport chain used for?
Pumping H+ against its concentration gradient.
Why is energy nonlinear?
I have no idea what you mean by energy being or not being linear. In math and physics, a relationship is linear if a graph of one quantity vs. another quantity is a straight line. It isn't clear what you are comparing the energy against. In other words, assuming you plot energy on the vertical axis, what you you plot in the horizontal axis?
Does osmosis work with or against the concentration gradient?
against the gradient
Does active transport move with or against the gradient?
Against the gradient. It requires energy because it's going against the concentration of high to low.
The transport of a substance across the cell membrane against its concentration gradient is called what?
The transport of a substance across the cell membrane against its concentration gradient is called active transport.
What is the process that requires cellular energy to move a substance against its concentration gradient?
Active transport uses energy to move substances against the concentration gradient.
What moves solutes against concentration gradient?
The processes that can move a solute against its concentration gradient are active transport. All cells are enclosed by a plasma membrane that is similar in structure and function.
What process is used to move proteins against the concentrarion gradient?
this is called active transport, bc it uses energy and goes against the concentration gradient
Proceeds Against a concentration Gradient requires a carrier?
Solute pump
What process is used to go against the concentration gradient?
active transport
Does simple diffusion work with or against the concentration gradient?
I think that it is something
Photosynthesis relies on gas defusion briefly describe the process of gas diffusion and explain what is meant by concerntration gradient?
well concentration gradient is when both sides are evened out and if both sides are evened out then they are withconcentration gradient but when they are not evened they are against concentration gradient!
What does the area under a force-extension graph represent?
The area under a graph of force against distance (or extension, if it's a spring) represents the work done by that force. Since it sounds like you're talking about a spring, you should know that the area would represent the work done to stretch the spring that distance, and also represents the amount of elastic potential energy contained by the spring.
What is measerment?
the comparison of unknown quantity against fixed with known quantity is called measurement.
