In today's world, the Industrial Revolution, the age of machinery, new technologies have developed rapidly with the production of goods that have opened doors for humankind. There have been new-age technologies that have helped speed up agricultural domains and result in overgrowing productions. 'Nature may have tricks up her sleeve to check us if the chemists exploit her too greedily' is related to today's context as overexploitation of resources is very harmful to today's Nature. When all these technologies override Nature without any control, we humans have to face many problems in the future. The use of chemical fertilisers in factories, agricultural fields create a varied impact on Nature. Thus, the author, G.B Shaw, means that there should be a check on natural resources.
A school is organizing a debate competition with participants as speakers and judges. $ S = \{S_1, S_2, S_3, S_4\} $ where $ S = \{S_1, S_2, S_3, S_4\} $ represents the set of speakers. The judges are represented by the set: $ J = \{J_1, J_2, J_3\} $ where $ J = \{J_1, J_2, J_3\} $ represents the set of judges. Each speaker can be assigned only one judge. Let $ R $ be a relation from set $ S $ to $ J $ defined as: $ R = \{(x, y) : \text{speaker } x \text{ is judged by judge } y, x \in S, y \in J\} $.
Given below is a heterogeneous RNA formed during Eukaryotic transcription:
How many introns and exons respectively are present in the hnRNA?
A certain reaction is 50 complete in 20 minutes at 300 K and the same reaction is 50 complete in 5 minutes at 350 K. Calculate the activation energy if it is a first order reaction. Given: \[ R = 8.314 \, \text{J K}^{-1} \, \text{mol}^{-1}, \quad \log 4 = 0.602 \]
