The correct Answer is:
To solve the question of marking the odd one with respect to the transverse section (T.S.) of a plant's part, we will analyze each option step by step: ### Step-by-Step Solution: 1. **Option 1: Vascular bundles are arranged in a ring.** - In a dicot stem, vascular bundles (which consist of xylem and phloem) are typically arranged in a ring. This is a characteristic feature of dicotyledonous plants. - **Conclusion:** This statement is correct and not the odd one. 2. **Option 2: Epidermis is covered by a thin layer of cuticle.** - The epidermis serves as the outer protective layer of the plant and is often covered by a thin layer of cuticle, which helps in reducing water loss. - **Conclusion:** This statement is also correct and not the odd one. 3. **Option 3: The cells of the endodermis have a deposition of water-impermeable, waxy material called lignin.** - The endodermis is the innermost layer of the cortex in roots. It is characterized by a deposition of a water-impermeable substance, but this substance is called suberin, not lignin. Lignin is found in other parts of the plant, such as in the xylem. - **Conclusion:** This statement is incorrect and is the odd one out. 4. **Option 4: Pericycle contains both sclerenchyma and parenchyma.** - The pericycle is a layer of cells located just inside the endodermis and can contain both sclerenchyma (which provides strength) and parenchyma (which is involved in storage and transport). - **Conclusion:** This statement is correct and not the odd one. ### Final Answer: The odd one out is **Option 3: The cells of the endodermis have a deposition of water-impermeable, waxy material called lignin.** ---

A screen is at distance D = 80 cm form a diaphragm having two narrow slits S_(1) and S_(2) which are d = 2 mm apart. Slit S_(1) is covered by a transparent sheet of thickness t_(1) = 2.5 mu m slit S_(2) is covered by another sheet of thickness t_(2) = 1.25 mu m as shown if Fig. 2.52. Both sheets are made of same material having refractive index mu = 1.40 Water is filled in the space between diaphragm and screen. A monochromatic light beam of wavelength lambda = 5000 Å is incident normally on the diaphragm. Assuming intensity of beam to be uniform, calculate ratio of intensity of C to maximum intensity of interference pattern obtained on the screen (mu_(w) = 4//3)

When a sound wave enters the ear, it sets the eardrum into oscillation, which in turn causes oscillation of 3 tiny bones in the middle ear called ossicles. This oscillation is finally transmitted to the fluid filled in inner portion of the ear termed as inner ear, the motion of the fluid disturbs hair cells within the inner ear which transmit nerve impulses to the brain with the information that a sound is present. The theree bones present in the middle ear are named as hammer, anvil and stirrup. Out of these the stirrup is the smallest one and this only connects the middle ear to inner ear as shown in the figure below. The area of stirrup and its extent of connection with the inner ear limits the sensitivity of the human ear consider a person's ear whose moving part of the eardrum has an area of about 50mm^2 and the area of stirrup is about 5mm^2 . The mass of ossicles is negligible. As a result, force exerted by sound wave in air on eardum and ossicles is same as the force exerted by ossicles on the inner ear. Consider a sound wave having maximum pressure fluctuation of 4xx10^-2Pa from its normal equilibrium pressure value which is equal to 10^5Pa . Frequency of sound wave in air is 332(m)/(s) . Velocity of sound wave in fluid (present in inner ear) is 1500(m)/(s) . Bulk modulus of air is 1.42xx10^5Pa . Bulk modulus of fluid is 2.18xx10^9Pa . Q. This person (without hearing aid machine) is sitting inside a busy restaurant where average sound intensity is 3.2xx10^-5(W)/(m^2) . How much energy in the form of sound is taken up by the person in his meal time of 1 h?

In a Young's double slit experiment, a parallel beam containing wavelengths lambda_(1)=4000Å and lambda_(2)=5600Å is incident at an angle phi=30^(@) on a diaphragm having narrow slits at separation d=2mm. The screen is placed at a distance D =40 cm from the slits. a mica slab of thickness t=5mm is placed in front of one of the slits and whole of the apparatus is submerged in water. if the central bright fringe is observed at C, determine.
