A graph shows the frequency distribution of the character (body size). B graph shows the relation between body size and fitness, within one generation, and the third the expected change in the average for the character over many generations (if body size is inherited).

 Among the diverse components of plant defense arsenals are proteins that interfere with herbivore digestion, Given some defense compound of plants in column I with its given action in column II

Column I

column II

I)  α-amylase inhibitors

a) Antidigestive proteins, block the action of herbivore proteolytic enzymes. After entering the herbivore’s digestive tract, they hinder protein digestion by binding tightly and specifically to the active site of protein-hydrolyzing enzymes such as trypsin and chymotrypsin

II) Lectins

b) block the action of the starch-digesting enzyme

III) proteinase inhibitors

c) A defensive proteins that bind to carbohydrates or carbohydrate-containing proteins. After being ingested by an herbivore, bind to the epithelial cells lining the digestive tract and interfere with nutrient absorption

Correctly match the defence compound withits action on herbivore;
