Continous is the variation which changes during time, like youe height, weight......
Discountinous varitation is the one which doesnt change during time, like the gender,blood group...

 this is correct sweety but we r supposed to know it like this;this is the base for y it changes with time and y it doesn't

Continuous variation are features/characteristics which are affected by both the environment and the genes like height and weight
Discontinuous variation are features/characteristics which are affected only by the genes and not by the environment like blood group,ability to roll your tongue,lobed ears

know abt the harmful effects of all these
herbicides r used to kill weeds that compete with important plants(crops) for nutrients and sunlight
insecticides r pesticides that kill insects specifically (the name says it) cuz pests r not only insects there r plant pathogens,molluscs,birds and many more
