Students were tasked with developing a model of how pesticide resistance is developed in a population of farming pests. Each student submitted the scenario they would model to their teacher. Which student’s model would be most useful in demonstrating how pesticide resistance develops in a population?
A. Student B proposes a model showing how the quantity of pesticide used, compares to population size after breeding season for the pests, and how this correlates with average temperature.
B. Student D proposes to model the application of pesticides and how before and after each application this affects the ratio of phenotypes in each generation and the growth of the crops after each application.
C. Student A proposes a model showing how the quantity of pesticide used compares to population size after breeding season for the pests, and how this correlates with rainfall.
D. Student C proposes to model the application of pesticides and how before and after each application this affects the ratio of phenotypes in each generation and the pest population size after each application.

D. Student C proposes to model the application of pesticides and how before and after each application this affects the ratio of phenotypes in each generation and the pest population size after each application.

Explanation:

This experiment has into account the variables associated with the pesticide resistance and their assessment

significant amounts of nitrogen oxides, carbon monoxide, and other pollution

explanation:

passenger vehicles are a major pollution contributor, producing significant amounts of nitrogen oxides, carbon monoxide, and other pollution. in 2013, transportation contributed more than half of the carbon monoxide and nitrogen oxides, and almost a quarter of the hydrocarbons emitted into our air.

relative dating involves things like higher layers are most recent than rocks lower in the sequence. this can be extended to the known sequence of fossils. rocks containing rabbit fossils are later than those containing dinosaur fossils.  

absolute dating methods mainly use radioactive elements that have known rates of decay and produce recognizable products. for example potassium 40 decays to produce argon. once a rock has solidified the argon is trapped. by measuring the argon and potassium0 you can get an accurate number for the age.  

some other methods are good for archaeological ages. dendrochronology involves recognizing the sequence of tree rings. the orientation of magnetized particles in baked clay can be used to date a fire.

hope this .. .
