a. The top of the atmosphere is at about 400 kV with respectto the surface of the earth, corresponding to an electric field that decreases with altitude. Near the surface of the earth, the field is about 100 Vm^(-1). Why then do we not get a electric shock as we step out of our house into the openy (Assume the house to be a steel cage so there is no field inside!) b. A man fixes outside his house one evening a two metre high insulating slab carrying on its top a large aluminium sheet of area 1m^(2) . Will he get an electric shock if he touches the metal sheet next morning? c. The discharging current in the atmosphere due to the small conductivity of air is known to be 1800A on an average over the globe. Why then does the atmosphere not discharge itself completely in due course and become electrically neutral? In other words, what keeps the atmosphere charged? d. What are the forms of energy into which the electrical energy of the atmosphere is dissipated during a lightning? (Hint: The earth has an electric field of about 100 Vm^(-1) at its surface in the downward direction, corresponding to a surface charge density =-10^(-9) Cm^(-2) ?.

Arrange the following statements in correct sequence: 1. These vapours condense to form tiny droplets of water. 2. The water droplets come together to form large water droplets. 3. The heat of the sun causes evaporation of water from the surface of the earth, oceans, lakes, rivers and other water bodies. 4. The large water droplets become heavy and the air cannot hold them, therefore, they fall as rains. 5. Water vapour is also continuously added to the atmosphere through transpiration from the surface of the leaves of trees. 6. Warm air carrying clouds rises up. 7. Higher up in the atmosphere, the air is cool. 8. These droplets floating in the air along with the dust particles form clouds.

Assertion:Colchicine reduces the chromosome number. Reason:It promotes the movment of sister chromatids to the opposite poles.

During cell division chromatin fibres become condensed to form thick structures called ………….

Failure of chromatids to segregate during cell division and resulting in gain or loss of chromosomes is called.

During karyokinesis, the spindle fibres get attached to condensing chromosome at a highly differentiated region. This region is called as
