The effect that disrupting tymbal organs had on the number of captures. The results if support the hypothesis that in Bertholdia trigona species, the tymbal organ has an echolocation jamming function. Given: In the given study, two groups of moths were studied. In one group of moths, the tymbal organs were punctured. In another group of moths, the tymbal organs were left intact. Next, the moths were released into the wild where they are preyed on by bats. Number of attacks and the number of captures were measured for both groups of moths. Introduction Bats are natural predators of nocturnal moths. They prey on these moths using echolocation abilities as they emit ultrasonic signals which help them locate the moths. Moths have evolved some forms of behavior to avoid capture by these bats. They either use rapid change in flying behavior like rapid dives or turning away. Alternatively they can use their unique tymbal organs to confuse the bats by producing ultrasonic sounds.

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…
