**Impact of Pesticide Usage on Bollworm Population**The bollworm is a pest that eats and damages corn crops. During their short lifespans, bollworms hatch, eat, mate, and lay eggs that hatch the following spring. In order to save her business, a local farmer has chosen to use a pesticide toxin that’s deadly to 90% of bollworms. The remaining 10% of the bollworm population carries a rare inheritable gene that makes them immune to the toxin.The farmer switches to using the pesticide in 2006. At first, this seems to solve her problem: her first crop showed very little sign of bollworm damage. As time went on however, the modified corn plants began to show increasing signs of damage. Less than 10 years later, the plants showed nearly the same damage as the original crops.### Table and Graph Analysis#### Bollworm Population Over TimeThe table below lists the number of immune and non-immune bollworms over the years:| Year | # Immune Bollworms | # Non-immune Bollworms ||------|--------------------|------------------------|| 2004 | 50 | 450 || 2005 | 48 | 447 || 2006 | 47 | 450 || 2007 | 60 | 410 || 2008 | 110 | 350 || 2009 | 150 | 300 || 2010 | 220 | 280 || 2011 | 325 | 325 || 2012 | 415 | 315 || 2013 | 345 | 300 || 2014 | 396 | 296 || 2015 | 403 | 295 || 2016 | 459 | 350 || 2018 | 478 | 340 |#### Bollworm Population Over Time GraphThe graph provides a visual representation of how the bollworm population has evolved over time, specifically indicating the number of bollworms that are immune and not immune to the toxin from 2004 to 2018. - The y-axis lists the number of bollworms.- The x-axis lists the years from 2004 to 2018.- Dark bars represent immune bollworms.- Light bars represent

Stress

Stress is defined as the feeling of being overwhelmed or unable to cope with emotional or mental pressure. Any event or action that makes a person annoyed, furious, or nervous can trigger it. Chemical changes in the body caused by stress can cause blood pressure, blood sugar levels, and heart rate to rise.

**Impact of Pesticide Usage on Bollworm Population**

The bollworm is a pest that eats and damages corn crops. During their short lifespans, bollworms hatch, eat, mate, and lay eggs that hatch the following spring. In order to save her business, a local farmer has chosen to use a pesticide toxin that’s deadly to 90% of bollworms. The remaining 10% of the bollworm population carries a rare inheritable gene that makes them immune to the toxin.

The farmer switches to using the pesticide in 2006. At first, this seems to solve her problem: her first crop showed very little sign of bollworm damage. As time went on however, the modified corn plants began to show increasing signs of damage. Less than 10 years later, the plants showed nearly the same damage as the original crops.

DOTa species The pesticide DDT was widely used in the 1940s as a method of insect control. In the late 1950s the first DDT-resistant mosquitoes were discovered, and eventually DDT-resistant mosquitoes were found globally. When DDT is used now, the development of DDT resistance in mosquito populations occurs in months rather than years.Which of the following best explains the observations concerning DDT resistance in mosquitoes? * The proportion of DDT-resistant mosquitoes in a population remains constant due to the metabolic costs of DDT utilization DDT is a chemical signal that delays normal reproductive cycles in many mosquito populations. Natural selection favors DDT-resistant mosquitoes that are already present in a population when DDT exposure occurs. Competition for limited resources causes mosquitoes to migrate to geographical areas that have richer supplies of DDT. A population of 1,492 finches is introduced to a rainforest. Over the next year, the finches showa death rate of…
The fruit fly Drosophila neotestacea carries a bacterial symbiont and can also be infected by a nematode worm. The figure shows the number of eggs produced by female fruit flies that are or are not infected by the nematode (two bars on the left vs two bars on the right) and that do or do not have the bacterial symbiont (red vs blue bars). 30 | Symbiont | No symbiont 25 15 10 5 Infected Not infected Assuming that the nematode benefits by being inside the fly, the fly- nematode relationship, when there is no bacterial symbiont, is best described as a(n). Select one: a. mutualism b. competition c. commensalism d. host-parasite relationship Number of eggs produced per ovary 20
You are maintaining a small population of fruit flies in the laboratory by transferring the flies to a new culture bottle after each generation. After several generations, you notice that the viability of the flies has decreased greatly. Recognizing that small population size is likely to be linked to decreased viability, the best way to reverse this trend is to cross your flies with flies from another lab. True or false

A Scientist, John Smith, was conducting research on aphids that can undergo both methods of reproduction.

Entomologists at the New York State Department of Agriculture are interested in determiningthe connection between pest insects infesting crop plants with populations of the same insectinfesting native plants in natural habitats. Long term trapping and monitoring studies haveestimated that on average 3% of the populations move between habitats (farm to natural and visversa) each generation. A new insecticide resistance allele (∆K) has begun to increase infrequency in the agricultural populations.
