Summary Introduction
To explain: The trial in which the most control crabs and experimental bled crabs died.
Concept introduction: Horseshoe crab belongs to Phylum: Arthropod. They are normally found around shallow ocean waters. Horseshoe crabs are living fossils. Though the horseshoe crabs look like crustaceans, they are marine arachnids.
Expert Solution & Answer
Explanation of Solution
The uniqueness of horseshoe crab is that they clot upon encountering bacteria. Therefore, they are used in experiments where highly virulent bacteria are involved. The blood of horseshoe crabs is taken and then, they are let out in their habitat in order to conserve their population, but this might also lead to their death. Therefore, experiments were conducted to check their survival after taking their blood and the results were obtained as seen in Fig.24.40 in the question.
In trial 5, the number of control crabs is 30; out of which, 1 died. In trial 5, the number of bled animals is 30; out of which, 6 died.
Conclusion
Conclusion: Trail group 5 marked the highest number of control crabs and bled crabs that died compared to the other trial groups.

Experiment on The Predator-prey Interactions Between Zebrafish and Daphnia1. Six 1-L beakers were filled with aged tap water.2. To test the effect of light on the survival of Daphnia, the 6 beakers were divided equally into 2 treatments: light & dark. Beakers assigned to the dark treatment were covered w/ aluminum foil.3. One zebrafish (about 2-3 cm) starved for 24 hours was placed in each beaker.4. Fifty (50) Daphnia sp. individuals were added in each beaker containing the starved zebrafish. The top of the beakers assigned to the dark treatment were covered with aluminum foil.5. One hour after, the zebra fish was scooped out & the no. of surviving Daphnia in each set-up were counted.

- mussel defenses induced by the presence of crabs? Hypothesis: Mussels increase investment in defense in the presence of crabs Null hypothesis: Mussels do not increase investment in defense in the presence of crabs Experimental setup: Seawater No crab Crab (fed fish, not mussels) Mussels Mussels Prediction: Mussels downstream of the crab tank will have thicker shells than mussels downstream of the empty tank. Prediction of null hypothesis: Mussels in the two tanks will have shells of equal thickness Results: 0.6- 0.4- 0.2 00 No crab Crab What conclusion can you draw from the figure above? Without direct contact, mussels can sense the presence of crabs. O Mussels can sense the presence of crabs only visually. O Mussels are increasing their shell thickness in response to water current. Shell thickness is a non-inducible defense. O Crabs hunt for mussels by focusing on the chemicals they emit into the water.

- In the Introduction, the authors set the stage for their experiment. What ecological issues were facing Yellowstone National Park when wolves were no longer there, and how were the researchers going to test the questions they wanted to ask? In 4 – 6 sentences, summarize the Methods section of this paper. One of the questions the researchers asked when they began their experiment was “With wolves now back on the Yellowstone landscape for 15 years, how has the reintroduction of wolves affected the recruitment of the woody browse species?” Use data from the Ripple and Beschta paper to support your answer. In any scientific paper, the Discussion is often the most hard-hitting, and where researchers elaborate and explain their results in the context of their experiment and the real world. Explain why when researchers tried culling some of the elk herd it did not have trophic effects, while reintroducing wolves did have trophic effects.

This includes ticks and other ectoparasites, but also dead skin and blood of the mammal. The attached image shows a red-billed oxpecker sitting on the back of a warthog with a tick in its bill. A recent study found that the depletion of African mammals due to habitat loss and hunting leads to declines in oxpeckers. Researchers were interested in whether the nature of the interaction between African mammals and oxpeckers was context-dependent. They compared the effect of removal of oxpeckers in two areas in which the number of ticks on the mammals differed. Given the data described in the introduction to this section, what effect do African mammals have on oxpeckers a) Positive b) negative c) neutralarrow_forward

They compared the effect of removal of oxpeckers in two areas in which the number of ticks on the mammals differed. In area 2, stomach content data of oxpeckers showed they consumed ~400 ticks per day. Cows were infested experimentally with large numbers of tick larvae and then oxpeckers were introduced at different stages in the tick life cycle (larvae; nymph; adult). They counted the number of adult ticks that dropped off the…arrow_forwardhttps://media.hhmi.org/biointeractive/click/lionfish-invasion/introduction.html Now you'll tie together what you've learned.
