Fifty seeds were selected at random from each 5 bags of seeds and were kept under standardised conditions favourable to germination . After 20 days , the number of seeds which had germinated in each collection were counted and recorded as follows : What is the probability of germination of (i) more than 40 seeds from a bag ? (ii) 49 seeds from a bag ? (iii) more than 35 seeds from a bag ?

A polling agency recently surveyed 1,000 adults who were selected at random from alargecity and asked each of the adults,“Are you satisfied with the quality of air in the city?”Of those surveyed,78 percent responded that they were satisfied with the quality of air in the city. Based on the results of the survey, which of the following statements must be true? I. Of all adults in the city,78 percent are satisfied with the quality of air in the city. II. If another 1,000 adults selected at random from the city were surveyed,78 percent of them would report they are satisfied with the quality of air in the city. III. If 1,000adults selected at random from a differentcity were surveyed,78percent of them would report they are satisfied with the quality of air in the city

Engage, explore, explain,elaborate and evaluate are five important 'Es' in relation to effective teaching of Science. To provide practical experiences to the students related to the concept of 'Necessary conditions for germination', a Science teacher asks them to do the following activites A. Soak seeds overnight and keep these in a wet cotton cloth. B. Observe the seeds after two days and record the changes. C. Read the book and attempt the given worksheet. Which of the five 'Es' given above are not being covered in the above activities given by the teacher ?

Collect some seeds sow them in a particular place in your school garden. Observe how many days each type of seed takes to germinate. Tabulate your observation.

Two bottles were half filled with water from Ganga ('P") and kaveri ('Q') and kept under identical airtight conditions for 5 days. The oxygen was determined to be 2% in bottle ('P') and 10% in bottle ('Q'). What could be the cause of this difference ?
