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

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.

answer: tributaries flow into rivers.

wetland is a biome that develops when the water gets accumulated in a land exhibiting a huge depression. these form either seasonally or permanently. the water in the wetland comes from rivers, lakes, ocean, flood, rain or other sources. the wetlands includes mangroves, marshes and peatland.

tributaries flow into the rivers develops a wetland because such water will get deposited in the depression and will restrict the original flow of tributary water. hence, water with low drainage current combines with the river water.
