A glass bulb is connected to an open limb manometre. The level of mercury in both limbs of the manometer was same. The bulb was heated to 57∘C. If the room temperature and the atmospheric pressure were 27∘C and 750 mm.Find the difference of levels in the two limbs now.
The diagram shows two air filled bulbs connected by a U-tube partly filled with a low density (or light) oil. How the levels of oil in the limbs X and Y change after the electric bulb is lighted

When the chromosome has a centromere near one end of a chromosome resulting in one shorter and one longer arm, the chromosome is called
