Chapter 1, Problem 3CT
Imagine you are a marine biologist and you notice that a certain type of crab tends to be larger in a local bay than in the waters outside the bay. What hypotheses might account for this difference? How would you go about testing these hypotheses?

Consider that you are a civilian resident living on the Chatham Island in New Zealand where a long-finned pilot whale stranding event with 100 beached whales is happening and maybe have even been participating in the response to the strandings. Raise specific questions that you may have for the local government or researchers about the stranding. Argue for an alternate hypothesis as to why the event occurred. Use and fully cite in-text peer-reviewed journals and government organizations, to support all data. Then, provide a full reference section at the end to list all the sources used
Question 1. What is the most recent estimated time of divergence between invertebrates and vertebrates, based on the ATPase 6 gene? What is the most distant?
Question 2. Based on the most recent plausible age, which gene gives the most recent time for the divergence between invertebrates and vertebrates? According to that estimate, how long ago was this?
Question 3. Based on the most distant plausible age, which gene gives the most distant time for the divergence between invertebrates and vertebrates? According to that estimate, how long ago was this?

- South America North America Pacific Panama Caribbean Panama The cladogram above illustrates the relationships between four hypothetical species of oysters found along the coasts of western North America, western South America, and western (Pacific) and eastern (Caribbean) Panama. Use this tree to answer the following question. The two species from Panama are separated from one another by the Isthmus of Panama, the narrow land bridge connecting North and South America, which formed approximately 2.5 million years ago. If sea levels rise and the Isthmus of Panama is submerged, allowing the Pacific and Caribbean species to expand their ranges until they overlap, will there be gene flow between the Pacific and Caribbean species currently living on either side of the isthmus? O No, because these species have been separated long enough that they are now different species, incapable of reproducing and having viable offspring. O Yes, because oysters don't have any reproductive behaviors or…arrow_forwardAn experiment was designed to analyze the metabolic rate of several bird species. A single bird was isolated in a chamber, and the amount of respired carbon dioxide was measured for 30 minutes. During this time, the heart rate of the bird was also measured. The table shows the average amount of carbon dioxide after three trials. Based on this data, which of the following species would you predict to have the smallest body mass? A - All species will have equal masses. B - Species A will have the smallest body mass due to its heart rate being the lowest. C - Species A will have the smallest body mass due to its exhaled carbon dioxide being the lowest. D - Species D will have the smallest body mass due to its exhaled carbon dioxide and heart rate being the highest.arrow_forwardn which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive dataarrow_forward

Note the location of the sea urchin in the model as the reference point for the observation.

Based on what you have learned in this lab and in the paper by Herron et al. 2019, what would be an informed response to this comment include? Select all that apply. Question 3 options: It is irrelevant that rotifers are multicellular in our study as some of the predators of small unicellular organisms are themselves unicellular, and predation, whether by a unicellular or multicellular organism, was all that was needed. Multicellularity evolved many times. While multicellular predators cannot have been responsible for the earliest transition from unicellular to multicellularity, they may have played a role in some of the later transitions which occurred after the evolution of animals. Using a multicellular predator is…arrow_forward

An asteroid crashed into the region where the birds lived and only affected their survival and not the other animals that lived there. C. Cannibalism within the species caused the population to decline. D. Each bird dove into the water even though it could not swim, which led to mass drownings. U E.
