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

- Changing conditions put intense pressure on organisms-some of which become extinct. For example, of the original 62 species of honeycreeper found in Hawaii only 18 remain. Scientists have the technologies that may allow bringing back organisms that have become extinct. This brings up ethical questions about the cost/benefit of resurrecting extinct species and whether it is the right thing to do. Joseph Bennett, a professor of biology at Carleton University in Ontario, wanted to determine the cost of resurrecting and maintaining an extinct species. Since the up-front cost of resurrecting an extinct species is very difficult to determine, the researchers decided instead to look at the cost of reintroducing and protecting a resurrected organism in the wild. To accomplish this, the researchers considered 70 animals from New Zealand and 29 animals from New South Wales that went extinct within the last 1,000 years. From this list, they chose 11 New Zealand species and five NSW species that…arrow_forwardWhen describing this experiment to your friends, they point out that rotifers are multicellular predators and thus cannot have been responsible for the earliest transition from single cell to multicellularity. 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_forwardIf we compare DNA sequences of related species pairs (human vs. gorilla and D. melanogaster vs. C. elegans), which species pair is likely to show the most adaptive differences with the related species? Is it the human-gorilla pair or the fruitfly-nematode worm pair? Justify your answer.arrow_forward
- Multicellularity has evolved multiple times in different lineages on Earth. What is one major advantage of multicellularity over unicellularity? Multicellular organisms can move faster than unicellular organisms Multicellularity allows for specialization of cells into different tissues and organs Multicellular organisms have higher fitness than unicellular organisms. Multicellularity allows organisms to reproduce more rapidly. Only multicellular organisms can reproduce sexually.arrow_forwardWhen is being genetically identical to the parent an advantage for organisms? Question options: When many offspring are needed in a short amount of time. When the environment is just like the one the parent lived in successfully. When no mates can be found. When the environment is changing and fast reproduction is needed. Sexual reproduction increases which of the following? Question options: Survival rates for all organisms The rate (speed) of evolution Mutations Genetic diversityarrow_forwardYou are examining an organism you believe to be an animal. Which of the following would NOT support your hypothesis? O A The organism appears to be heterotrophic. O B The organism appears to be multicellular. O C The organism appears to be motile.

There are many phyla within the animal Kingdom, and in this activity, you will explore these phyla by building a dichotomous key that will allow you to consider almost any animal and determine which phylum it belongs to. Part 1: Organizing information for the dichotomous key 1) List the 9 animal phyla of macroscopic (visible) animals: Porifera, Cnidaria, Platyhelminthes, Nemotoda, Annelida, Arthropoda, Mollusca, Echinodermata, and Chordata. 2) Use on-line or library resources of your choice, to gather information about these 9 phyla. a. Start by finding two example species per phylum to help tie into your previous knowledge about animal types. Write down these examples. b. Make a list of characteristics that you could use that would help you tell these 9 phyla apart. The final goal is to build a…arrow_forwardYour friend remarks, "The giraffe stretched its neck while reaching for higher leaves; as a result, its offspring inherited longer necks” Which statement is the best response to correct your friend’s misconception? Group of answer choices Overproduction of offspring leads to a struggle for survival. Disuse of an organ may lead to its eventual disappearance. Characteristics acquired during an organism's life are generally not passed on through genes to its offspring. Only favorable adaptations have survival value.arrow_forward
