Textbook Question
Chapter 48, Problem 15TYU
EVOLUTION LINK The number of protonephridia in a planarian is related to the salinity of its environment. Planaria inhabiting slightly salty water develop fewer protonephridia than those inhabiting less salty water, but the number of protonephridia quickly increases when the concentration of salt in the environment is lower. How is this increase adaptive? Explain.

True Falsearrow_forwardConsider 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? 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.arrow_forward

A species of shrimp soon moves into the burrow with the gobi fish. The gobi fish is blind and only comes out of the burrow when the shrimp leads it to a patch of algae near its den. What type of relationship is represented by this fish and shrimp? OMutualism OParasitism OCommensalism Osaphrophytismarrow_forwardYou discover a new species of bacteria that grows in aquatic environments with high salt levels. While studying these bacteria, you note that their internal environment is similar to the salt concentrations in their surroundings. You also discover that the internal salt concentrations of the bacteria change as the salt concentration in their environment changes. The new species can tolerate small changes in this way, but dies from large changes because it has no mechanism for altering its own internal salt levels. What type of homeostatic mechanism is this species using to regulate its internal salt levels? regulation integration assimilation conformationarrow_forward

- write in 5 paragraphs answer this Plants and animals both arose in the seas and moved onto land during evolution. This move to land required the evolution and adaptation of several key features to survive in a dry environment (versus being surrounded by water). Compare and contrast different mechanisms to avoid desiccation in Kingdom Plantae and Kingdom Animalia.arrow_forwardDinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves. Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…arrow_forwardDinoflagellates are unicellular, marine protists.
