Mosquitoes can carry and transmit many diseases to humans. In the past, the insecticide DDT was heavily used to reduce mosquito populations in order to reduce instances of disease transmission. However, after some time, mosquito populations developed a resistance to DDT, which made the DDT less effective in reducing mosquito populations.
Based on what you’ve learned about natural selection, in 3–5 sentences, describe how mosquitoes may have come to develop this resistance.

Scenario: Natural selection is a process by which organisms with favorable traits produce more successful offspring than organisms with less favorable traits, causing the favorable traits to become more common in the population. In the southern United States, two different tree frog species, green tree frogs and gray tree frogs, are an example of this. They both live in some of the same parts of the country and eat the same things. They both also live off of the ground and lay eggs in water.
Can you write a scientific explanation that explains why the tree frog species are different colors?

- Evolution: Describe an example of another species that has undergone evolution in response to human-driven changes to its environment.arrow_forwardNow, let's investigate growth in another population: bedbugs! Let's say a college in Kentucky experienced a bedbug infestation, and biology students were asked to help study the problem. Bedbugs are insects that live inside of mattresses (and other similarly warm places) and feed on the blood of sleeping humans. The origin of the bedbug infestation was traced to a student who accidentally brought a few bedbugs in his luggage, after spending a long weekend in New York City. Bedbugs reproduce sexually. In an infested room with a 4 m2 dorm bed, biology students find a population of 1200 bed bugs. In one month, they find that 240 bedbugs die, and 600 new bedbugs hatch. The maximum number of bedbugs is limited by the size of the bed that they live in. What is the density of bedbugs in the dorm bed studied by the biology students? (Explain)arrow_forwardWhich is an example of evolution? In Florida, the brown tree lizard has taken the trees from the green tree lizard. The feet of green tree lizards have become less sticky in recent years, making it harder for the green lizards to climb higher in the trees to escape the brown tree lizards. Mice have become more sensitive to poison, which has resulted in them dying quicker when they eat the poison in mouse traps. Bed bugs have developed thinner exterior shells and more sensitive nerve cells that are less resistant to the chemicals that are used to kill them. Due to global warming, the winters in Finland have been milder, resulting in less snow. The brown tawny owls in Finland are showing higher survival rates than the pale grey owls because they can blend into the trees to hide from predators.arrow_forward
- Look carefully at the picture below and you will see an insect called a katydid. Katydids evolved from grasshoppers through natural selection. Use this to explain how could have this happened.arrow_forwardConsider Lamarck’s idea in a hypothetical situation. For example, you decided that when you have children, you want them to be big ang strong. You decided to go to the gym every day for a year. You did all your exercise routines diligently and you were able to develop really bulky and toned muscles because you believed that your kids would inherit your big impressive muscles. Do you think this would work? Justify your answer using the concepts you have learned from Genetics, as well as Darwin’s concept of evolution.arrow_forwardOf the following, which one is an example of an evolutionary explanation (as opposed to a functional explanation)?A. People evolved a fear of snakes because many snakes are dangerous.B. Humans have a (tiny) tailbone because our ancient monkey-like ancestors had a tail.C. People evolved an ability to recognize faces because that ability is essential for cooperative social behaviors.D. People evolved a tendency to form long-term male–female bonds because human infants benefit from the help of two parents during their long period of dependence.arrow_forward
- Many species of animals make alarm calls, which warn others in their group that a predator is approaching. Alarm calls also attract the atten- tion of the predator, making it more likely that the individual making the call will be eaten. Why might natural selection favor the evolution of alarm calls in a species? How might you test that hypothesis?arrow_forwardBASED ON THIS GRAPH: A small community that is heavily infested with mosquitoes was sprayed weekly with the insecticide DDT for several months. Daily counts providing information on mosquito population size are represented in the graph below. Provide a biological explanation for the changes in the mosquito population over time. Use the terms: insecticide resistance/resistant, natural selection, favorable trait, reproduce, mutation/sexual reproductionarrow_forwardYour friend remarks, "The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks” Which statement is the best response to correct your friend’s misconception? Group of answer choices Characteristics acquired are generally not passed on through genes to its offspring. Only favorable adaptations have survival value. Body that are used extensively become larger and stronger. Overproduction of offspring leads to a struggle for survival.arrow_forward
- It has taken millions of years for the ancestors of whales to change into what we know today, as indicated in the diagram below. Based on your knowledge of evolution, which of the following is a reasonable explanation of why the organisms in the diagram changed over 25 million years? Question options: As the environment changed the food sources became more difficult to obtain so characteristics that allowed the organisms to hunt in an aquatic environment became more advantageous. As the environment changed the temperature became too hot and the organisms began to move to a more aquatic environment to keep cool. As the environment changed the food sources became more difficult to obtain so the organisms decided to change their characteristics to ones that would be beneficial when hunting in an aquatic environment. As the environment changed the predators on land became better adapted to hunting the whales ancestors forcing them to live in more aquatic…arrow_forwardSuppose that global warming causes ocean rise that obliterates most of the Gulf Coast of Florida and much of its human population, and that radiation leaking from the destroyed Big Bend Nuclear Power Station causes a mutation that yields green hair in humans with the homozygous recessive mutant allele. Many years pass and a new island appears in the Gulf. This island is then colonized by an intrepid human population that is fixed for the recessive green hair allele. If the island population grows to 10,000 individuals and then an individual who is heterozygous for the green hair locus arrives on the island and mates with one of the residents, how many generations will it take for the dominant, non-green hair allele to reach a frequency of 99%? (Assume viability selection 20% in favour of the non-green allele and ignore the effects of genetic drift).arrow_forwardSuppose that global warming causes ocean rise that obliterates most of the Gulf Coast of Florida and much of its human population, and that radiation leaking from the destroyed Big Bend Nuclear Power Station causes a mutation that yields green hair in humans with the homozygous recessive mutant allele. Many years pass and a new island appears in the Gulf. This island is then colonized by an intrepid human population that is fixed for the recessive green hair allele. If the island population grows to 10,000 individuals and then a new mutation arises once in the population, with a single individual becoming heterozygous for the green hair locus, a) What is the probability that this non-green hair allele will reach fixation by genetic drift? (Assume no selection or additional mutation at this locus). b) What is the average time to fixation of this new non-green allele?arrow_forward
