Consider the following statements regarding the importance of diffusion and choose the correct answer:
1. The exchange of gases takes place by the principle of dependent diffusion
2. The process of diffusion is involved in transpiration of water vapours
3. The ions are absorbed by the simple diffusion during passive salt uptake
4. Diffusion is an effective means of transport of substances over a very short distance and helps in the translocation of food materials
Match List 1 with List 2 and choose the correct answer form the code given below: List 1 (Cultural diffusion) List 2 (Definition) (a) Relocative  1.Upward/downward movement of dispersal through a system of classes or centres (b) Hierarchical Diffusion  2. When acceptance of or information about an innovation spreads throughout the society (c) Expansion Diffusion  3. When expansion affects almost uniformly to all individuals and areas from a source region (d) Contagious Diffusion  4. Geographical transfer of culture traits by movements of people across space
Assertion (A) From its inception, the study of organisational change has noted the fact that many participants respond with dogged resistance to altering the status quo. Since the industrial revolution began, workers have at times sought, occasionally in extremely violent fashion, to block the introduction of new technology.
Reason (R) Such behaviour may be either overt or covert. Overt resistance may take the form of employees deliberately failing to do the things necessary for successful change or simply being unenthusiastic about the change.
Covert resistance can be more detrimental to change than open resistance because it is harder to identify and eliminate.
Identify the characteristics of psychological behaviour according to the cognitive field theory of learning and motivation: (a) An overt purposive act (b) Reinforcement contingent response (c) An attitudinal shift (d) Behaviour with longer latency (e) A change in the perceived value of an object (f) Behaviour showing associative shifting (g) A new relationship established between two or more events. Select from the options to given your answer:
From the following list, identify those which are relevant for the theory of rational choice: (a) Aggregation of social behaviour (b) Random behaviour (c) Determinants of behaviour (d) Prediction of behaviour (e) Study of interest groups (f) Behaviour problems associated with information Indicate your answer from the codes. Select the correct option:
In a gas mixture of hydrogen and oxygen, steady state equimolar counter diffusion is occurring at a total pressure of 100 kPa and temperature of 20°C. If the partial pressures of oxygen at two planes 0.01 m apart, and perpendicular to the direction of diffusion are 15 kPa and 5 kPa, respectively and the mass diffusion flux of oxygen in the mixture is 1.6 * 10–5 kmol/m2.sec, calculate the molecular diffusivity for the system. For equimolar counter current diffusion:
If 'blue' means 'green', green' means 'yellow' 'yellow' means 'orange', 'orange' means 'black', 'black' means 'white', 'white' means 'red', 'red' means 'pink', 'pink' means 'brown', 'brown' means 'grey', than what is the color of human blood?
Read the following passage and answer the item that follows. Your answers to this item should be based on the passage only. An innovative India will be inclusive as well as technologically advanced, improving the lives of all Indians. Innovation and R&D can mitigate increases in social inequality and relieve the pressures created by rapid urbanization. The growing divergence in productivity between agriculture and knowledge-intensive manufacturing and services threatens to increase income inequality. By encouraging India's R&D labs and universities to focus on the needs of poor people and by improving the ability of informal firms to absorb knowledge, an innovation and research agenda can counter this effect. Inclusive innovation can lower the costs of goods and services and create income-earning opportunities for the poor people. Which among the following is the most logical and rational assumption that can be made from the above passage?
