Golgi apparatus is absent in
Glycosylation of proteins is done by
Gas in a cylinder is maintained at $10 \,atm$ pressure and $300\, K$ temperature. The cylinder will explode if pressure of gas goes beyond $15\, atm$. What is the maximum temperature to which gas can be heated?
F-centre is
Diagrams of hypogynous, perigynous and epigynous flowers are given below. Find out the option that correctly exemplifies A, B, C and D.
Developing spermatozoa receive nutrition from
Zone refining is based on the solubility of impurities in the molten state than in the solid state of the metal. Pure metal oxide is obtained in zone refining.
Water waves in a river are not polarized. Water waves are longitudinal as well as transverse in nature.
Transpiration occurs only when stomata are open. Transpiration occurs only through stomata.
Surface tension decreases with increases in temperature. On increasing temperature kinetic energy increases and intermolecular forces decreases..
$Si??i$ bonds are much stronger than $Si??$ bonds. Silicon forms double bonds with itself.
Respiratory pathway is an amphibolic pathway. In respiration, there is breakdown of many substances (catabolism) and synthesis of many substances (anabolism) by respiratory intermediates.
$Pb_3O_4$ reacts with $HNO_3$ and forms $PbO_2$. Lead is stable in $+4$ oxidation state.
Oxidation state of hydrogen is +1 in $H_2O$ while -1 in $CaH_2$. $CaH_2$ is a metal hydride and for hydrides, hydrogen is assigned the oxidation number of -1.
Oxidation of glucose by $Br_2$-water gives saccharic acid. $Br_2$-water oxidises ??HO and ??H group.
On passing electric current in colloidal solution they do not move towards anode or cathode. They do not contain any charge.
Net primary productivity is gross primary productivity minus respiration. Secondary productivity is produced by heterotrophs.
Metal deficiency defect can be seen in $FeO$. $Li$ compound (LiCl) has pink colour due to F-center.
Gallium arsenide phosphide is used for making LED. Valance band overlaps with conduction band in case of semionductor.
For angular projection, when angle of projection ? = tan (1), the horizontal range is four times the maximum height. The horizontal range of projectile is directly proportional to square of velocity and inversely proportional to acceleration due to gravity.
Due to Frenkel defect, there is no effect on the density of the crystalline solid. In Frenkel defect, no cation or anion leaves the crystal.
Colpa aurea is a specialised pollinating agent of orchid Ophrys speculum. Male Colpa mistakes the Ophrys flower for female wasp to copulate with it.
Auerbach?? plexus controls the secretion of intestinal juice. Meissner?? plexus controls the peristalsis in alimentary canal.
