WRITE ABOUT A THEME: INTERACTIONS Animal life changed greatly during the Cambrian explosion, with some groups expanding in diversity and others declining. Write a Short essay (100-150 words) interpreting these events as feedback regulation at the level of the biological Community.

- Climate change causes problems for organisms that have adapted to their environments. Please list two problems that climate change could cause which would prevent organisms from surviving in an environment to which they are well adapted.arrow_forwardCheck Your UnderstandingWrite the word TRUE if the statement is correct; if not, write the WORD that makes it false. Cladosporium cladosporioides is used for biodegradation. Speciation and extinction can be seen in the temporal pattern of biodiversity. The barrel concept can be used to explain the effects of limiting factors.arrow_forwardTwo species of fish live in the Pacific ocean. The first species, Bigous fishis, can only live in the upper level of the sea close to the surface. The second species, Littlout fishis, lives in the lower levels of the sea near the ocean floor. However, without the presence of Bigous fishis, the Littlous fishis, can live in all the parts of the ocean. For Bigous fishis, the lower level of the sea would be considered_______For Littlous fishis, the entire ocean would be considered their_________and the lower levels of the ocean would be considered their________ A.

- In essay format talk about the characteristics of monkeys, cheetahs, lions, and west caucasion tur then using these animals and including giraffes, wildebeests, camels, and donkeys explore how these animals share similar characteristics but show diversity based on their different living environments, Compare these similarities and differences such as structural and behavoural differences. Then analyze some risks and benefits of human intervention to the biodiversity of mammalia and analyze the impact that climate change might have on the diversity of mammalia and these animals specifically.arrow_forwardYou have now studied three different types of anatomical structures. Homologous structures show individual variations on a common anatomical theme. These are seen in organisms that are closely related. 1. Give an example of a homologous structure from this activity: Analogous structures have very different anatomies but similar functions. These are seen in organismsthat are not necessarily closely related but live in similar environments and have similar adaptations. 2. Give an example of an analogous structure from this activity: Vestigial structures are anatomical remnants that were important in the organism's ancestors but are nolonger used in the same way. 3. Give an example of a vestigial structure from this activity: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_forward
- Read the research on each pair of organisms for information on how they interact with each other. Based on your reading, state the type of relationship they have, the symbols for that type of relationship, and the evidence you used to explain and support your decision.arrow_forwardCreate a diagram illustrating the level of the organizational structure of the Tilapia fish. To begin, you will examine the fish as an organism. What structures did you notice? How are these structures constructed? How might this tilapia contribute to the ecosphere?arrow_forwardFour organisms are analyzed for various biological features as described below. Plant Multicellular Fossils found in Fossils with Fossils with fruiting Fossils with stromatolites teeth bodies stomates A No Yes No No No B Yes No Yes No No Yes No No Yes No Yes No No No Yes Part A: Explain how to tell which major groups of living things these come from and how to tell whether they may come from an aquatic habitat or from a terrestrial habitat, if it is possible to tell. Part B: Decipher which organism comes from what major groups of organisms and explain how you deciphered this. B red 000 吕口 F3 F1 F2 O00 F4 F7 F8 % 2 3 6 8 W E R T * 00arrow_forward
- What is the main idea of this text? In the years right after the invasion, zebra mussels evolved and adapted to the Hudson River ecosystem. In the years right after the invasion, zebra mussels evolved and adapted to the Hudson River ecosystem. In the years right after the invasion, zebra mussels caused a number of changes in the Hudson River ecosystem and food web. In the years right after the invasion, zebra mussels caused a number of changes in the Hudson River ecosystem and food web. In the years right after the invasion, zebra mussels did not have a major impact on the Hudson River ecosystem or food web. In the years right after the invasion, zebra mussels did not have a major impact on the Hudson River ecosystem or food web. At first, zebra mussels did not have any impact on the Hudson River ecosystem, but their impact increased over timearrow_forwardAt what level of organization do humans and zebra mussels diverge? Question 1 options: Phylum Kingdom Domain Classarrow_forwardPart A Which of the following statements regarding the diversification of animals is supported by the current available evidence? sponges are a paraphyletic group of organisms ctenophores are basal metazoans most animals belong to the clade Bilateria animals descended from multiple ancestors Submit Provide Feedback Request Answerarrow_forward
