Using the following data, calculate the filtration coefficient for the capillary bed:
Plasma colloid osmotic pressure = 30 mm Hg
Capillary hydrostatic pressure = 40 mm Hg
Interstitial hydrostatic pressure = 5 mm Hg
Interstitial colloid osmotic pressure = 5 mm Hg
Filtration rate = 150 ml/min
Venous hydrostatic pressure = 10 mm Hg

The colored pigments of plants are of two principal types: carotenoids and flavonoids. Given below some statements of about these pigments;
a) Anthocyanins
are colored flavonoids that attract animals
b) Flavonoids are phenolic compounds that include a
wide range of colored substances
c) Carotenoids are coloured terpenoid compounds that
also serve as accessory pigments in photosynthesis
d) most widespread group of pigmented carotenoids is
the anthocyanins, these are glycosides that have sugars. Without their sugars,
anthocyanins are known as anthocyanidins
Which of the following is incorrect statements of these pigments;
