Explain how the creation of refuges for insect pests can counteract the evolution of pesticide resistance...
How can one do plant breeding for developing resistance to insect pests? Give a few examples to insect resistance characteristics. Also mention the source of pest resistance genes.
What is antibiotic resistance? Thoroughly explain. What is pesticide resistance? Thoroughly explain. What are the causes of antibiotic and pesticide reistances? Thoroughly discuss. What can humans do to prevent development and expansion of antibiotic and pesticide resistances? Thoroughly justify.
Q4.15. DDT is an insecticide that was used extensively in agriculture in the mid-1900s to kill many insect pests, including the boll weevil (pictured below), another pest of commercial cotton. DDT was initially effective at controlling boll weevil outbreaks, but after about a decade DDT became much less effective, because many populations of boll weevil had evolved resistance to DDT. Which of the following conditions would biologists say was required for the evolution of DDT resistance in a population of...
Write a detailed paragraph on how natural selection can help explain evolution.
8.Evolution explains both the unity and diversity of life. Explain how evolution can account for both why rabbits and opossums share certain traits and also why they differ. 7. In lab last week, you compared the two mammal species Eastern Cottontail and North American Opossum to learn how to construct dichotomous keys. Compare now using the Deep Tree of Life. http://www.pbs.org/wgbh/nova/lablablevolution research levo/deeptree a. How long ago did the Eastern Cottontail and North American Opossum share their most recent common...
Tired of collecting data at night, you decide to switch to a project studying whether pesticide-resistance genes from GMO crops are being spread among neighboring farms by pollinators. On Farm X, all of the corn plants are heterozygous at the pesticide resistant gene (genotype Aa). The "A" allele is dominant and confers resistance to pesticide. All of the corn plants planted on Farm Yare homozygous for aa (i.e. they have no copies of the A allele). If you know that...
What are the common myths about evolution and why are they wrong? Name and describe the three results of natural selection that can create changes in the percentages of alleles in a population? What are the allopatric and the sympatric speciation? Give examples of each. What are the two major types of barriers that result in reproductive isolation? Give several examples of each type that prevents the result of healthy, fertile offspring between two different species. Trace our hominid ancestor...
A) Is natural selection progressive? Why or why not? B) Explain how evolution can influence genotype-by-environment interactions. Provide an example to assist your explanation.
explain difference between natural selection and genetic drift and how each can influence evolution in different ways. Should not be less than 200 words
