biconcave वाक्य

The red blood cells of mammal s are typically shaped as biconcave disks : flattened and depressed in the center, with a dumbbell-shaped cross section, and a torus-shaped rim on the edge of the disk.
Shape change of erythrocytes under applied forces ( i . e ., shear forces in blood flow ) is reversible and the biconcave-discoid shape, which is normal for most mammals, is maintained after the removal of the deforming forces.
Forewing : basal two-thirds black brown, with basal patch, costal streak, and reniform stigma fuscous grey; crossed at middle by a pale ochreous band oblique from subcostal and widening downwards, its outer half yellowish; limited externally by a biconcave ochreous band, narrower below, followed below vein 6 by a broad brown band, on the outer edge of which are three or four irregular black patches, and above and beyond it on costa a black blotch, sharply angled externally on vein 6, these black marks forming the inner edge of a diffuse submarginal pale line; terminal area shaded with brown and fuscous, with a short black apical streak and a diffuse dark cloud below the middle; fringe grey with white base, altogether whitish round apex : hindwing olive fuscous, becoming blackish towards termen; a white band from costa at one-third to anal angle, and a round white submarginal spot in submedian fold; fringe brightly white, but grey between veins 2 and 4; the form " stupida"
