process by which organisms maintain a relatively stable internal environment
Cell Transport
The process of moving material in and out of cells.
Concentration
The spread of something over a given area.
Equilibrium
A state of balance
Diffusion

biology
Find the tangent line to $f(x)=\frac{x^{2}}{a+1}$ at x = a. Assume that a is a positive constant.
chemistry
The particles that make up a rock are constantly in motion. However, a rock does not visibly vibrate. Why do you think this is?
chemistry
For the reaction $$ \mathrm{A}(a q)+\mathrm{B}(a q) \rightleftarrows \mathrm{C}(a q) $$ $\Delta G^{\circ}=-1.95 \mathrm{~kJ} / \mathrm{mol}$ at $25^{\circ} \mathrm{C}$. What is $\Delta G$ (in $\mathrm{kJ} / \mathrm{mol}$ ) at $25^{\circ} \mathrm{C}$ when the concentrations are $[\mathrm{A}]=[\mathrm{B}]=0.315 M$ and $[\mathrm{C}]=0.405 M$ ? (a) $-1.95 \mathrm{~kJ} / \mathrm{mol}$ (b) $1.53 \mathrm{~kJ} / \mathrm{mol}$ (c) $-5.43 \mathrm{~kJ} / \mathrm{mol}$ (d) $8.16 \mathrm{~kJ} / \mathrm{mol}$ (e) $-12.1 \mathrm{~kJ} / \mathrm{mol}$
computer science
Algorithms `generate` and `generate_n` use a(n) _______ function to create values for every element in a *range* of container elements. That type of function takes no arguments and returns a value that can be placed in an element of the container.
