- 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…How do honey bees communicate information about food vectors? What is the honey bee waggle dance?

- You want to distinguish between two hypotheses to explain the patterns you see: 1) Males not feeding the young is an adaptation to dimorphism 2) If males don't feed the young in a species, it will allow them to become brightly colored To begin to address this question, map the characters changes in dimorphism and males feeding the young onto each of the trees on the previous page. CHARACTER SEXUAL DIMORPHISM MALES FEED YOUNG Cassin's Vireo No No Red Fox Sparrow Cape May Warbler Cedar Waxwing Golden-Crowned Kinglet Pyrrhuloxia Yes No No No No Yes No Yes Yes No California Gull No Yes Note: This data is fictional 5) Which of the hypotheses in part 4 is consistent with your analysis? Explain why in a brief paragraph.What is Brood parasitism? Give an example. What adaptation has evolved in this phenomenon?Thinking Analytically There are more parasitic species of animals than all other sorts of animals combined. (If this sounds impossible, consider how many animals parasitize any animal you can think about, including ourselves.) Why do you think parasitism is such a runaway success? What are the drawbacks of being aparasite?
- Mimicry of yellowjacket wasps by clearwing moths is an example of a harmless species resembling a dangerous one. What is the ad-vantage to the moth of this form of mimicry? What is the advan-tage to a dangerous species of mimicking another dangerous species?Activity 4. Make a Dichotomous Key.

These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.

This results in a permanent dipole, leaving a partial positive charge on the hydrogens. The extra electron density on the oxygen leaves a partial negative charge. Therefore, water is a polar molecule and has the ability to form hydrogen bonds. These properties explain many of water's characteristics, including…Read this quote from Charles Darwin (from Origin of Species). What is he describing? "Thus, I can understand how a flower and a bee might slowly become, either simultaneously or one after the other, modified and adapted to each other in the most perfect manner, by the continued preservation of all the individuals which presented slight deviations of structure mutually favorable to one another." An interaction network. A predator/prey cycle. O Coevolution. An obligate mutualism.Organisms have developed defense mechanisms to protect themselves from predation. These defense mechanisms include protective colouration Mullerian mimicry Batesian mimicry cryptic colouration chemical defense Match the following examples to the type of protective mechanism listed above.Stripes of a skunk AnswerA fawn with fur colouring that camouflages it in the forest AnswerTwo species of poisonous butterfly with the same colour pattern AnswerA hawkmoth with the same black and yellow body markings as a wasp Answer
