To measure the population of lake trout in a 250 hectare lake, 200 individuals were netted and marked with a fin clip, and then returned to the lake. The next week, the lake is netted again, and out of the 200 lake trout that are caught, 50 have fin clips. Using the capture-recapture estimate, the lake trout population size could be closest to which of the following?

Members of the Poaceae family, which includes all of the cereal crops, use benzoxazinoids, these alkaloids shows;

a) Alkaloids are derived from the tryptophan as constitutively produced defensive secondary metabolites

b) These benzoxazinoids such as DIBOA and its derivative DIMBOA are usually stored in the peroxisome

c) Upon damage, the inactive glycosides are hydrolyzed, generating glucosinolate, which are toxic not only to insect herbivores but also against pathogens

d) DIBOA and DIMBOA perform insecticidal and pesticidal activities
