- Asian tiger mosquito Trace its origin and evolutionary history or changes in the species. Describe its structures and their functions. What is the importance of this species to our environment? Give trivia about this species. Does this organism produce oxygen? Explain. What are the ancestral species of your chosen organism? Has this species been genetically engineered? If yes, in what way? How does this species reproduce? What organisms have similar structures to this species? Do these structures have the same function? Does the species have tissues, organs, and/or organ systems? What is its role in the flow of energy? Give at 15 least a sentence to each question.WRITE ABOUT A THEME: Organization You have seenmany examples of how form fits function at all levels of thebiological hierarchy. However, we can imagine forms thatwould function better than some forms actually found innature. For example, if the wings of a bird were not formedfrom its forelimbs, such a hypothetical bird could fly yet alsohold objects with its forelimbs. In a short essay (100–150words), use the concept of “evolution as tinkering” to explainwhy there are limits to the functionality of forms in nature.Describe the step-wise process of how inorganic matter on primitive Earth evolved into multicellular, eukaryotic cells. Be sure to provide enough detail with each step and make sure you cover inorganic, organic, protocells, prokaryotic, energetics, eukaryotic, and multi-cellularity
- 1. Based on the Cytochrome C data, which organism is most closely related to humans?2. Do any of the organisms have the same number of differences from human Cytochrome C? In situationslike this, how would you decide which is more closely related to humans?3. Charles Darwin published his book On the Origin of Species in 1859. Of the different types of evidence thatyou have examined, which do you think he relied upon the most, and why?NOTE: ANSWER THE 3 SUBQUESTIONS. From the choices below, select which perfectly describes the situation: CHOICES a. Capacity for Precise Self-Replication and Self-Assembly b. Defined Functions for Each of their Components and Regulated Interactions Among Them c. Systems for Extracting, Transforming and Using Energy from the Environment d. Mechanism for Sensing and Responding to Alterations in their Surroundings e. A High Degree of Complexity and Microscopic Organization f. A History of Evolution Change SITUATIONS: 1.1. Even though organisms tend to be of same species, they exhibit different feature or characteristic which is brought about by their adaptation at a certain condition; thus, evolution is dependent on the specific environmental condition the organisms are living in, as well as can be specific to a particular species. Which among the distinguishing characteristics of living organisms explains this? 1.2. All organisms experience environmental pressure which threatens their…One of the simplest definitions of a life-form is anything with the capacity to reproduce and regulate itself. Before life began, the complex organic, or hydrocarbon-bearing, molecules that makeup RNA and DNA, the building blocks of life, must have formed. No one knows exactly how life is formed from these molecules, but many ideas have been put forward. As you enter this area, go toward the large video screen on the right and explore the “Life at the hydrothermal Vents” label deck. Some scientists theorize that life begins at deep-sea vents. Find three lines of evidence to support this claim.
- An astrobiologist discovers a new form of life on another planet. Life here appears to have evolved using DNA as the information storage molecule and proteins to carry out cellular function, much like on Earth, however the individual building blocks on this planet are different. On this planet, there appear to be 3 different nucleotides in the DNA and 30 different amino acids in the proteins. Which of the following conclusions about this form of life would be most justified? These organisms can produce proteins no more than 30 amino acids in length. These organisms must produce 30 different forms of mRNA Amino acids must be coded by sets of 3 nucleotides in the DNA of the organisms on this planet. Amino acids must be coded by sets of at least 4 nucleotides in the DNA of the organisms on this planet. These organisms cannot produce more than 30 kinds of protein.1) Describe how the structure of a protein (such as hemoglobin) is related to DNA. In other words, what does the structure of a protein tell us about the DNA structure of a gene? 2) Geology and the Geological Time Chart. Using the Geological Time, answer the following questions. __________________ Which evolved first, amphibians or trees? __________________ There was a major extinction that occurred between the Permian and Triassic periods. Over 90% of all marine life and around 70% of vertebrates went extinct! How long ago did this extinction take place? __________________ There was another major extinction between the Cretaceous and Tertiary periods. This is when the dinosaurs and most other reptiles went extinct. How long ago did this happen?1. We have sent two objects into distinct space with information meant to be found by an extraterrestrial intelligence, the Pioneer Plaque and the Voyager Golden Record. Pick one of these objects and describe three things included. 2. In class we discussed the emergence of intelligent life on Earth. Why might or might not this be considered an evolutionary advantage? 3. In biological terms, what is the definition of a species?
- Science fiction movies have been known to sketch out a world of the near-future where terrible things have happened such as the evolution of antibiotic resistance in flesh-eating bacteria. What might we reasonably say about this topic? (Select all that apply) A - While one can have fun with entertaining stories about evolution (including ones that are very plausible), this is not a good reason to fund research on antibiotics because that is a solved medical problem. B - It has already happened with some early antibiotics (like penicillin)-the only reason we are momentarily okay is the continued development of additional antibiotics. C - In principle, it is possible but evolution takes millions of years, so don't expect it in the near-future. D - The bodies of humans have evolved since the discovery of antibiotics such that they are less and less effective already. E - We shouldn't find antibiotic resistance to be evidence for evolution because it is only a science-fiction story: it…Atlantic Thorny oyster.

But how did the first living cells appear?
