Consider why there might be natural selection for poisonous plants to warn potential herbivores with bright colors, but why there seems to be no similar selective pressure for poisonous mushrooms to do the same. Which of the following best explains this difference? Tooo a) Fungi, like mushrooms, do not rely on photosynthesis and hence do not need to attract or warn herbivores with bright colors. Plants have a symbiotic relationship with herbivores, which is not the case for mushrooms. Mushrooms are typically more toxic than plants, so there is no need for them to develop warning colors. Most of a fungus's body is the mycelium which exists underground, hence consumption of the above-ground mushroom cap represents a comparatively smaller fitness cost than for plants, whose vital photosynthetic structures can be consumed by herbivores.

The Darwin Moth is the sole pollinator of a particular type of orchild. What type of symbiotic relationship exists between these organisms?
Many people like to eat spicy foods, but most other mammals don’t. Historically, the general trend was that the hotter the climate, the spicier the foods a society traditionally favored. Using these facts as a starting point, what might be the selective advantage for plants that can manufacture spicy chemicals? Why might it be useful for humans to tolerate, and even enjoy, spicy food?
Which of the following scenarios may demonstrate an organism selecting a resource non-randomly? (Hint: think about the availability versus use of each type of resource .) a. )A tide pool contains twice as many red urchins as purple urchins. Otters eat twice as many red urchins as purple urchins . B. ) In a desert with equal numbers of creosote and saltbush, ants gather only creosote seeds. C. ) In a desert of only creosote bushes, ants gather creosote seeds. D. ) A tide pool contains twice as many purple urchins as red urchins. Otters eat twice as many red urchins as purple urchins.
Which of the following is NOT an adaptation among plants to increase access to nitrogen? Mutualistic association with fungi that convert atmospheric nitrogen into a biologically available form Carnivory of insects and other invertebrates None of the above are adaptations that increase access to nitrogen All of the above are adaptations that increase access to nitrogen Mutualistic association with bacteria that live within the root tissue and convert atmospheric nitrogen into a biologically available form
Coral reefs are unique, living structures. Even though they appear to be hard, rock-like structures, the soft-bodied coral animals that build the elaborate, hard, rock-like reef structures around themselves live inside. Corals are unique animals because they have photosynthetic algae that live inside their cells. This unique relationship is beneficial to the algae since it has a safe place to live inside the coral cells, and it is beneficial to the coral since the algae are producing food via photosynthesis. From the description above, what type of symbiosis is described, and at what ecological level does this relationship exist? The relationship is an example of parasitism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the community level. The relationship is an example of commensalism, and it exists at the community level. The relationship is an example of mutualism, and it exists at the…
In 1955, conservationists in Hawaii were concerned about an invasive species, the giant African land snail, Achatina fulica. A. fulica was reproducing widely and had few predators. In an attempt to control the invader and protect the environment, the conservationists imported the rosy wolf snail, Euglandina rosea (E. rosea), that preys on other snails for food. Which of the following explains what will most likely happen to A. fulica? Why? E. rosea quickly becomes the top predator, instead of A. fulica. The number of A. fulica decreases. A. fulica and E. rosea become competitors, but A. fulica remains the top predator. The number of A. fulica stays constant. A sudden genetic mutation in A. fulica causes them to become smaller and more attractive to E. rosea. The number of A. fulica decreases. Natural selection causes A. fulica to grow bigger, be more aggressive, and eat more snails, including E. rosea, over time. The number of A. fulica increases.
The Lazy River Environmental Group is a group of fishermen and environmentalists that have worked to assess and clean up the pollution from an old factory on the Lazy River. One early study revealed that species on the river had absorbed pollutants from the water. Select the Pollutant Levels in Tissue, by Species dataset and follow the interactive to graph the data. Which statement(s) correctly describe the graph? (Check all that apply.) The two species with highest levels are both fish.The two species with highest levels are both fish. Turtles had a pollutant level about three times that of clams.Turtles had a pollutant level about three times that of clams. No invertebrate (excludes fish and turtles) had a level above 0.05 ppm.No invertebrate (excludes fish and turtles) had a level above 0.05 ppm. The fish species with the highest level was about three times the value of the fish species with the lowest level.The fish species with the highest level was about three…

Which of the following situations has revealed that mutualistic interactions can evolve from prior parasitic relationships? A. Yucca plants are pollinated only by moths of the genus Tegeticula; however, some of the moth species 'cheat" by laying eggs on seeds without pollinating the plant. B. Large-sized lice of the genus Columbicola tended to live on larger species of pigeons. Body size matching had a significant effect on the ability of lice to escape defensive preening by the host bird. C. The nonvenomous yellow-eyed salamander has the same coloration as the toxic California newt. Related nontoxic salamanders which do not mimic the newts are prone to attacks by predators. D. Glochidion trees and Epicephala moths are in an obligate mutualism with each other. Significant cospeciation led to an increase in diversity of the two species.
Discuss how adaptations allowed plants to move from an aquatic environment to the variety of habitats they inhabit today. Maybe, start out by discussing single celled algae and include the transition from prokaryotes to eukaryotes. Then explain why those traits are adaptive, and how they arose. Don't forget the role of natural selection in adaptation.

According to the video, what was the effect of artificially-modified ant density in acacias on the elephant feeding behavior? (Choose one.) a. As the number of ants swarming increased per minute on acacia branches, so did the number of branches fed on by elephants. b. As the number of ants swarming increased per minute on acacia branches, the number of branches fed on by elephants decreased. c. As the density of ants per A. depranolobium increased, the number of trees fed on by elephants decreased. d. Elephants fed more frequently on Acacia depranolobium trees with their ants removed than on A. depranolobium trees with ants. video link: https://www.youtube.com/watch?v=s3blzcbll7Q&t=293s
