EDTA is a hexadentate ligand: one EDTA ion binds a metal ion through six donor atoms, so it forms complexes with coordination number 6.

Ordinary plastics are non-biodegradable, so bacteria and fungi cannot break them down in any useful length of time. Most plastics, such as polyethylene, polypropylene and PVC, are long synthetic polymers made from petroleum.

The pardoning power is exactly the power by which the sovereign, acting through the President, can set aside or soften the result of its own courts' judgment, so saying it is never exercised against the judicial mandate is wrong.

In Opuntia and in many Euphorbia species the leaves are reduced to spines to cut down transpiration, and the stem takes over photosynthesis by becoming flattened, green and fleshy; such a stem is a phylloclade.

The mud of a tidal swamp is waterlogged and almost free of oxygen, so these plants send up roots that grow vertically out of the soil into the air and take in oxygen through pores; such roots grow against gravity and are therefore called negatively geotropic.

The banyan's horizontal branches grow so long and heavy that they send down thick aerial roots which reach the soil, thicken into pillars and carry the weight of the branch; these are called prop or pillar roots.

The carrot stores food in its primary root, which is broad at the top and tapers steadily to a point, and that shape is described as conical.
