Biology is the science of life and living organisms. Aside from instruction relevant to this, students are given the chance to learn complex laboratory techniques (e.g., DNA extraction) as well as develop mindful opinions about controversial topics in biology (e.g., stem-cell research and genetic modification).

This process can occur either through direct contact between cell surfaces such as cell junctions or indirect interaction, where cells attach to surrounding extracellular matrix, a gel-like structure containing molecules released ...
Thermodynamically the flow of substances from one compartment to another can occur in the direction of a concentration or electrochemical gradient or against it. If the exchange of substances occurs in the direction of the gradient, that is, in the direction of decreasing potential, there is no requirement for an input of energy from outside the system; if, however, the transport is against ...
