To carry out an integrated pest management(ipm) program, you need to recognize abnormal conditions and identify their causes, understand the different control methods available, and determine the costs and benefits of treatment. a) water your crops extensively b) scout and monitor your fields c) plant the same crop year after year d) apply broad spectrum pesticides annually

Correct B). Scout and monitor your fields

Integrated pest management is a long-term pest prevention or the damage caused by using the combination of techniques like biological control, modification of cultural practice, use of resistant varieties of seeds and habitat manipulation technique.

The main principle involved in the process of integrated pest management is to identify the pest and their host. Then establish monitoring guidelines for each pest.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

cells use diffusion to get substances in and out of themselves. that diffusion will occur across the cell membrane or the outer covering of the cell. because we are talking about the surface of the cell, surface area and volume are  important factors here. as a cell increases in size, its surface area and volume increase as well.  we call that the surface area to volume ratio (sa: vol).  but the catch is that  volume increases at a greater rate than surface  area. in other words, as a cell gets bigger, the sa: vol gets smaller. so a really small cell like bacteria is mostly cell membrane (surface) with very little contents (volume). a really big cell like an egg, is mostly insides with a super thin membrane. so what ends up happening is that the cell cannot efficiently diffuse all of the stuff it needs in/out to survive. therefore cell size is limited to about 100mm. so how do we make organisms bigger than 100mm? cells divide! by dividing and becoming multicellular, organisms are able to grow!   check out the diagrams i attached to see the effect of sa: vol. i hope this ! good luck!
