Re: WBJEE Entrance Exam Question Paper
Hi friend below I am giving you the West Bengal Joint Entrance Examinations Board Biology Question Paper 1. Passage cells help in (A) transport of water towards pericycle (B) transport of water towards epiblema (C) absorption of water from soil (D) passage of CO2 towards stomata Ans : (A) Hint : Passage cells are endodermal cells lacking casparian strip which allow comparatively faster movement of water into stele. 2. Medullary rays are tissues made up of (A) phloem parenchyma (B) xylem parenchyma (C) sieve tube (D) sclerenchyma Ans : (B) Hint : Medullary rays or Wood rays are made up of xylem parenchyma. 3. An allosteric inhibitor of the enzyme acts by binding to the (A) substrate (B) product (C) catalytic site of the enzyme (D) non-catalytic site of the enzyme Ans : (D) Hint : Allosteric inhibitor attaches with non catalytic site of enzyme called ‘Allosteric site’ 4. A set of genes will be in a complete linkage when the progeny phenotypes for parental (P) and recombinant (R) types are (A) P = 0%, R = 100% (B) P = 50%, R = 50% (C) P < 50%, R > 50% (D) P = 100%, R = 0% Ans : (D) Hint : Since there is complete linkage, parental combinations are 100% and recombinant types are 0% 5. Which one of the following statements is WRONG in relation to transgenic Bt cotton plant? (A) Crop yield loss due to attack by Bacillus thuringiensis bacterium is reduced (B) Crop yield loss due to attack by lepidopteran insect pests is reduced (C) The use of chemical insecticides in the cotton field is minimized (D) Better quality cotton is produced Ans : (A) Hint : Bacillus thuringiensis does not attack cotton plants and hence cannot reduce crop loss.
