The correct answer is:
Option 2: Colchicum
Colchicine is a toxic compound used primarily in the treatment of gout and for inducing polyploidy in plants. It is extracted from the Colchicum plant, specifically from the species Colchicum autumnale (autumn crocus).
The other plants listed are not used for extracting colchicine:
Tulip (Option 1): Not a source of colchicine.
Aloe (Option 3): Known for its medicinal properties, especially for skin care, but not related to colchicine extraction.
Asparagus (Option 4): Primarily known for its culinary uses and not for colchicine extraction.
Thus, Colchicum is the correct plant used to extract colchicine.
Colchicine is a chemical compound used in biotechnology and medicine, especially for inducing polyploidy in plants by interfering with spindle formation during cell division.
It is extracted from the plant Colchicum, commonly known as autumn crocus or meadow saffron.
Correct answer: Colchicum
A block of certain mass is placed on a rough floor. The coefficients of static and kinetic friction between the block and the floor are 0.4 and 0.25 respectively. A constant horizontal force \( F = 20 \, \text{N} \) acts on it so that the velocity of the block varies with time according to the following graph. The mass of the block is nearly (Take \( g = 10 \, \text{m/s}^2 \)):
A wooden block of mass M lies on a rough floor. Another wooden block of the same mass is hanging from the point O through strings as shown in the figure. To achieve equilibrium, the coefficient of static friction between the block on the floor and the floor itself is
The circuit shown in the figure contains two ideal diodes \( D_1 \) and \( D_2 \). If a cell of emf 3V and negligible internal resistance is connected as shown, then the current through \( 70 \, \Omega \) resistance (in amperes) is:
