2.10 Selenium (Se) Selenium is found in the body in an important group of enzymes (glutathione peroxidases) which have important antioxidant properties and work in conjunction with vitamins C and E to destroy free radicals in cells. Some studies have shown that a higher selenium level is linked to a lower risk of breast, prostate and colon cancer, which may in part be due to selenium's antioxidant function.

Geometrical isomerism can b 1.3 Parallel and perpendicular lines We often wish to know whether two lines are parallel (that is, they never meet) or perpendicular (that is, they meet at right angles). Two distinct lines, y = m1x + c1 and y = m2x + c2, are parallel if and only if they have the same gradient; that is, if and only if m1 = m2. For example, the lines y = −2x + 7 and 5.1.2 In what context was the text published? This amounts to asking, when was it written and for what audience.
