(c) Copper(ll) ions (Cu2+) inhibit the function of a proportion of the chlorophyll a present in single-celled, photosynthetic protoctists.
The concentration of functional chlorophyll a in these organisms was measured in two
different months of the same year in an unpolluted lake and in a lake polluted with
copper ions.
The results are shown in Table 3.1.

condensation. good luck!

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
