A child consumed an ice cream shaped in an inverted right circular cone, from the top and left only 12.5% of the cone for her mother. If the height of the ice cream is 8 cm, what was the height of the remaining ice cream cone ?

A system of greater disorder of molecules is more probable. The disorder of molecules is reflected by the entropy of the system. A liquid vapourizes to form a more disordered gas. When a solute is present, there is additional contribution to the entropy of the liquid due to increased randomness. As the entropy of solution is higher than that of pure liquid, there is weaker tendency to form the gas. Thus, a solute (non-volatile) lowers the vapour pressure of a liquid, and hence a higher boiling point of the solution. Similarly, the greater randomness of the solution opposes the tendercy to freeze. In consequence, a lower temperature must be reached for achieving the equilibrium between the solid (frozen solvent) and the solution. The elevation in boiling point (DeltaT_(b)) and depression in freezing point (DeltaT_(f)) of a solution are the colligative properties which depend only on the concentration of particles of the solute and not their identity. For dilute solutions, (DeltaT_(b)) and (DeltaT_(f)) are proportional to the molarity of the solute in the solution. Dissolution of a non-volatile solute into a liquid leads to

Draw a diagram of cross - section of the human heart and label the following parts : (i) Right ventricle (ii) Aorta (iii) Left atrium (iv) Pulmonary arteries.

A student, while observing an embryo of a pea seed in the laboratory, listed various parts of the embryo as given below: Testa, Tegmen, Radicle, Plumule, Micropyle, Cotyledon. On examining the list, the teacher remarked that only three parts are correct. Select the three correct parts from the list:

Which of the following statements are true? If false, correct them: (a) Boron deficiency leads to stout axis. (b) Every mineral element that is present in a cell is needed by the cell. (c) Nitrogen as a nutrient element, is highly immobile in the plants. (d) It is very easy to establish the essentiality of micronutrients because they are required only in trace quantities.

Which of the following statement is correct about Digestive system of Cockroach? (i) Mouth opens into a short tubular pharynx, leading to a narrow tubular passage called oesophagus. (ii) Gizzard helps in grinding the food particles. (iii) A ring of 6-8 blind tubules called hepatic or gastric caeca is present at the function of foregut and midgut, which secrete digestive juice. (iv) At the junction of midgut and hindgut is present another ring of 100-150 yellow coloured thin filamentous malpighian tubules which help in removal of excretory products from haemolymph.
