Sponge - Sponge - Form and function: Sponges are unusual animals in that they lack definite organs to carry out their various functions. The most important structure is the system of canals and chambers, called a water-current system, through which water circulates to bring food and oxygen to the sponge. The water-current system also helps disperse gametes and larvae and remove wastes.

pH, Buffers, Acids, and Bases Introduction to Chemistry

Key Points. A basic solution will have a pH above 7.0, while an acidic solution will have a pH below 7.0. Buffers are solutions that contain a weak acid and its a conjugate base; as such, they can absorb excess H + ions or OH – ions, thereby maintaining an overall steady pH in the solution.; pH is equal to the negative logarithm of the concentration of H + ions in solution: pH = – log[H +].
