Match the following  Special Techniques Are Used in Nutritional Studies;

A.) Hydroponic growth system	1.) plant roots lie on the surface of a trough, and nutrient solutions flow in a thin layer along the trough over the roots and this system ensures that the roots receive an ample supply of oxygen
B.) Nutrient film growth system	2.) In this technique, plants are grown with their roots suspended in air while being sprayed continuously with a nutrient solution, This approach provides easy manipulation of the gaseous environment around the root
C.) Aeronic growth system	3.) The technique of growing plants with their roots immersed in nutrient solution without soil and requires a large volume of nutrient solution or frequent adjustment of the nutrient solution to prevent nutrient uptake by roots from producing radical changes in nutrient concentrations and pH of the medium.

In a typical Mendelian population, individuals carrying gene ‘a’ in homozygous condition suffer from phenylketonurea. Those with A in homozygous condition are normal. Others, who are heterozygotic with Aa, are carriers. If the frequency of ‘a’ in a population is 0.20, what is the percentage of normal individual in the population?

A population of insects is in Hardy-Weinberg equilibrium for a gene with alleles A = orange and a = yellow eyes. There are 91% orange and 9% yellow individuals in the population. If the fitness of the yellow phenotype suddenly drops to zero, what will be the allele frequency in the next generation?
