Textbook Question
Chapter 28.6, Problem 4CC
MAKE CONNECTIONS Ø The bacterium Wolbachia is a symbiont that lives in mosquito cells and spreads rapidly through mosquito populations. Wolbachia can make mosquitoes resistant to infection by Plasmodium; researchers are seeking a strain that confers resistance and does not harm mosquitoes. Compare evolutionary changes that could occur if malaria control is attempted using such a Wolbachia strain versus using insecticides to kill mosquitoes. (Review Figure 28.16 and Concept 23.4.)

MAKE CONNECTIONS Like animals, cyanobacteria havea circadian rhythm. By analyzing the genes that maintainbiological clocks, scientists concluded that the 24-hourrhythms of humans and cyanobacteria reflect convergentevolution (see Concept 26.2). What evidence would havesupported this conclusion? Explain.
WHAT IF? The myxoma virus kills up to 99.8% of infectedEuropean rabbits in populations with no previous exposureto the virus. The virus is transmitted between living rabbitsby mosquitoes. Describe an evolutionary trend (in eitherthe rabbit or virus) that might occur after a rabbit population first encounters the virus.

Imagine 4 hypothetical parasites that use humans as a definitive host that have evolved, in isolation, on Australia (an island). Which of the 4 (described below) would be most likely to successfully colonize Madagascar (another island, distant from Australia, and already populated by humans) if a group of 8 infected Australian humans emigrated to Madagascar?
a. A trematode that uses direct penetration to infect humans and has 3 intermediate hosts.
b. A cestode with an indirect life cycle and trophic transmission
c. An apicomplexan transmitted to humans by a biological vector.
d. A nematode with a direct life cycle and fecal-oral transmission.

- MAKE CONNECTIONS Explain how natural selection could increase the resemblance of a harmlessspecies to a distantly related harmful species. In addition to selection, what else could account for a harmlessspecies resembling a closely related harmful species?

Use the steps to explain how PCB resistance became so common among tomcod in the Hudson. Be sure to include the terms mutation, fitness, selective pressure, and adaptation in your explanation. 2. In this blog post, the author describes the tomcod as "a quick learner" because of the population's adaptation to PCBs. Is "learning" an accurate way to describe the change in the Hudson River tomcod population? Why or why not? 3. The data shown on the map above support the hypothesis that natural selection for PCB resistance has occurred among tomcod in the Hudson. What sort of evidence regarding gene frequencies in different populations would argue against this hypothesis (i.e., imagine what the scientists would have observed in this study if natural selection on the AHR gene had not occurred among Hudson River tomcod)? 4.

Chloroplasts are photosynthetic. Aerobic bacteria evolved before photosynthetic bacteria (cyanobacteria).

- Explain in short plz. Asap. Thanks Imagine a population of cacti living on an imaginary island called Plantopia. These cacti evolved to stop producing spines because there are no herbivores on Plantopia. Every year, a few cactus seeds are washed onto the shores of Plantopia from the mainland. There are many large herbivores on the mainland. (Tip: Try drawing the scenario to help you visualize it.) Name three mechanisms of evolutionary change ( 3 of mutation, natural selection, genetic drift, andgene flow.) that may be acting on alleles for spine production on Plantopia. For each mechanism, explain what effect it may have on spine production, and whether this change is adaptive or non-adaptive.arrow_forwardTest Your Understanding Know and Comprehend 3.
