Given below are four jumbled sentences. Pick the option that gives their correct order. A. According to hair loss experts, excess DHT drastically increases collagen production in the hair follicle. B. Hair loss can be traced to an increase of internal Dihydrotestosterone (DHT) and collagen production. C. Eventually, collagen blocks the pore completely causing a lack of necessary blood flow due to which your hair loses its sheen, thins down and finally you lose your hair completely. D. When too much collagen lines the interior of the follicle, it narrows the pores, decreases blood flow and slowly strangles your hair to death.

Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:

Eight north Indian Ocean countries, namely, Bangladesh, India, the Maldives, Myanmar, Oman, Pakistan, Sri Lanka and Thailand, were asked to contribute names so that a combined list could be compiled. Each country gave eight names and a combined list of 64 names was prepared. This list is currently in use, and all cyclones arising in the north Indian Ocean are named from this list, with one name from each country being used in turn. Almost 38 or 39 names from the list have been used up, but since many cyclones dissipate long before they hit land, their names rarely figure in the papers or other media. The names that people do know about, and remember are, naturally, those that were most destructive ones, or very recent. Aila, in 2009 is remembered with a shudder for the enormous destruction it caused in West Bengal and Bangladesh; Phaillin, also for the damage it caused when it hit the Odisha coast in 2013. Two harmless cyclones, which also might remain in peoples memory, are the more recent ones of 2014 — Hudhud, which threatened the east coast of India and Nilofar, which was expected to, but did not, devastate the western coast. The names in the cyclone list are usually words one associates with storms; words which mean water or wind or lightning in various national languages. Sometimes they are names of other things — birds or flowers or precious stones. The name Aila, contributed by the Maldives means fire, the name Phaillin from Thailand means sapphire, the name Hudhud from Oman is the name of a bird, probably the hoopoe, and the name Nilofar, given by Pakistan, is the Urdu name of the lotus or water lily. The eight names suggested by India, and which are in the list of 64, are Agni, Akaash, Bijli, Jal, Leher, Megh, Sagar and Vayu, meaning in that order, fire, sky, lightning, water, wave, cloud, sea and wind. Five of these names (that is, up to Leher) have been used so far.
For the next cyclone if it is the turn of an Indian name to be chosen, then what will be that name?
'Nail' is related to 'Nail-cutter' in the same way as 'Hair' is related to ?
