Peacock Butterfly Predator Defenses The photographs below represent theexperimental and control groups used in the peacock butterfly experiment discussedin Section 1.6. See if you can identify the experimental groups and match them upwith the relevant control group(s). Hint: Identify which variable is being tested in eachgroup (each variable has a control).

- Figure 1.15 Example of error bars in a graph. This graph was adapted from the peacock butterfly research described in Section 1.5. The researchers recorded the number of times each butterfly flicked its wings in response to an attack by a bird. The squares represent average frequency of wing flicking for each sample set of butterflies. The error bars that extend above and below the dots indicate the range of valuesthe sampling error. Figure It Out: What was the fastest rate at which a butterfly with no spots or sound flicked its wings?arrow_forwardselect all that applyarrow_forwardLook at the two graphs in Figure 52-21.

What information can factorialarrow_forwardIdeally, an experimental group differs from a control group (a) only with respect to the hypothesis being tested (b) because its subjects are more reliable (c) in that it is less subject to bias (d) in that it is less vulnerable to sampling error (e) only with respect to the variable being studiedarrow_forwardPlease help me with this and explain.

- 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? * nd 2 school 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…arrow_forwardContinuing with the side-blotched lizard study... What would be an appropriate control group to use in this study?
