Solution and Explanation
(i) Three Database Retrieval Tools from NCBI: The National Center for Biotechnology Information (NCBI) offers several database retrieval tools that allow access to biological information. Some of them include:
Entrez: Entrez allows users to access literature, sequences and structures, and it provides a very broad access to various types of information related to biology and medicine.
Taxonomy Browser: The Taxonomy browser provides taxonomic classification of various organisms (like animals, bacteria, plants etc).
Locus Link: Locus Link provides information on official gene names, descriptive information about the genes and about homologous genes.
(ii) Information in UniProtKB and PDB:
UniProtKB: The UniProtKB (Universal Protein Knowledgebase) provides detailed information about proteins, including annotated protein sequences, functions, structures and other related information.
PDB: The PDB (Protein Data Bank) provides information about the three-dimensional structure of proteins and other macromolecules. This is a key database in structural biology, and allows researchers to view the structure of the proteins.

- Ankur Sachdeva did his MBA from ITB University. He decided to apply his knowledge of scientific management in the fast food restaurant chain 'Coffee Bean' set up by him. This restaurant was providing burgers, fries, shakes etc, as a part of its menu. Nowadays people are quality conscious, so he was using standardised raw materials, processes, methods, working conditions, machinery etc. The objective was to establish standards of excellence. By doing this he was not only able to reduce the cost but was also able to provide new varieties of burgers, fries and shakes leading to increased turnover. Ankur Sachdeva also believed that there was only one best method to maximise efficiency. As a result he developed best way of grilling burgers, cooking fries and preparing shakes. His main objective was to maximise the satisfaction of customers, which he was able to achieve. Not only to learn the best way of doing a job, but to perform their tasks efficiently, 'Coffee Bean' regularly invests in training and development programmes to equip employees with the necessary skill and knowledge. 'Coffee Bean' believed that efficient employees will produce more and earn more. This will ensure their greatest efficiency and prosperity for both company and workers. The above case highlights the use of Scientific principles and techniques by 'Coffee Bean'. Explain any one such principle and two techniques.

- Preeti started her own cooking channel on 'Youtube Mood Art'. As her subscribers increased, she was not in a position to manage everything on her own. She hired Rahul and Riya to help her with filming editing, lighting and content research. She granted authority to them to operate within prescribed limits. She was thus, able to use her time on high priority activities like developing new recipes and content development etc. As a result, Rahul and Riya were given opportunities to develop and exercise initiative. Preeti was now able to focus on objectives and meet the target of achieving a subscriber base of one million in six months.
