Match the following deficiency diseases with the nutritional factor (shown under the table) whose absence provoked these conditions (you can use the factor or corresponding letter (a, b, .)1. childhood blindness2. marasmus3. anemia4. kwashiorkor5. mental retardation6. pellagra7. low-toned8. rickets9. beri-beria. proteinb. fiberc. vitamin Ad. vitamin Bl (thiamine)e. vitamin Cf. vitamin Dg. vitamin Eh. niacini. iodinej. ironk. overall calorie/protein shortageC. True/False. Indicate T or F in the space before each numbered question. If the rehearsal is false, revise it below in the box provided to make a correct statement focus your response on the words in bold.1.
