What is the exposer of the plant shown during necrosis or chlorosis to high fluoride concentration? Correct Answer Leaf tip and leaf margins

  • In dicotyledonous broad leaves, the initial symptom of fluoride effects on leaves is usually chlorosis of the leaf tip.
  •  Later it extends downward along the margins and inward toward the midrib.
  • This chlorosis becomes more intense and extensive with prolonged exposure until the midrib and some veins appear as a green arborescent pattern on a chlorotic background.
  • Continued exposure may lead to the tip becoming necrotic and falling off, leaving the leaf notched.

A bar tender replaces some quantity of alcohol having 40% concentration with water and thus the concentration of alcohol changes to 30%. If the alcohol which he replaced is mixed with another sample of 260 ml alcohol having 20% concentration, then a mixture having 27% concentration of alcohol is prepared. Find the initial quantity of alcohol having 40% concentration.
The concentration of oxygen at the inner surface of the vessel is maintained at a level C depending on the pressure in the vessel, while the concentration at the outer surface is reduced to zero by the escape of oxygen to the surroundings. A steady state will eventually be reached when the concentration everywhere reaches a constant value.

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:
The given bar graph represents data of the production of paper (in ten lakh tonnes) by three different companies X, Y and Z during the years 2008 to 2012. The x-axis shows the 'years' and the y-axis represents the 'production of paper (ten lakh tonnes)'. (Note: The data shown is only for mathematical exercise. They do not represent actual figures.)  The total production of Company Y during 2008 and 2009 and Company X for 2011 and 2012 taken together is p% (p is correct to the nearest integer) more than the total production of Company Z during 2010, 2011 and 2012. The total production of Company Z during 2008 and 2009 taken together is q% (q is correct to the nearest integer) less than the total production of Company X during 2008, 2009 and 2012 and Company Y during 2010 and 2011 all together.  What is the positive difference between p and q ?
