Write True if the statement is correct. If false, change the underlined word or phrase to make the statement true. Write your answers on the blanks. 1. Modern species look similar to their ancestors because they are descended from them but with modification. 2. Paleontology helps in understanding the organisms that have lived during prehistoric times. All organisms emanated from different ancestors. Individual organisms differ from one another. Some of their differences are inherited. 3. 4. Genes play important roles in the evolution of organisms. 6. Descent with modification is the change in the DNA of an organism. 5. 7. Artificial selection is mostly associated with organisms that survive in the environment. 8. Many plants and animals today are remarkably well-suited to the environment they live in. 9. A key factor in the survival of organisms is how well they adapt to their environment. 10. Because most present-day humans no longer live in natural environments, natural selection is…

Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply.   Scenario 1:Scientists have developed genetically engineered plants that are pest-resistant. By adding genes to the plant's DNA, they become toxic to insects (but not to plants or animals). This means that these plants may not need to be sprayed with pesticides to ward off the insects. Would you be willing to eat these genetically altered crops? Explain your answer.  What are some possible impacts (positive or negative) of this genetically engineered plant on the environment, society, and individuals?   Scenario 2:Jan's sister and mother have both had breast cancer. She is wondering if she should undergo genetic testing to check for a mutation of the BRCA1 gene. A mutation in the BRCA1 gene is commonly associated with,…

I need help answering these questions for these figures. I'm not sure how to interpret it.

Hello, I need help answering number 8 a, b, & c using the phylogeny below. Pls & thank you! 8. a) As you know, the largest mass extinction in the history of life on earth was the Permian extinction that occurred about 252 million years ago. The therapsids are often described as “mammal-like reptiles”. If the Permian extinction had caused the extinction of the therapsids, would mammals as we know them now have evolved? Why or why not? 8. b) Many lines of evidence, including biochemical evidence, show that living birds are direct descendants of dinosaurs. A number of dinosaur lineages had feathered dinosaurs, not just the lineage that includes living birds. Do you think that is it justified to believe that all feathered dinosaurs had behaviors known from living birds? Such behaviors of birds include colonial nesting, sexual displays by males using feathers, males moving to display their ornamental feathers to female mates. Give a brief reason for your answer. 8. c) A…

Hi, I'm gonna post the other two questions differently, so I only need the first 2 ones for this one. Thank you.

please write your response to 1 of the options below. Ensure you include specific details of your ideas. Also, explain WHY you have chosen to highlight those aspects and make connections between the materials and your own previous knowledge and/or lived experiences.  #1: Science is not done in a vacuum by singular hero-scientists -- it is a team effort. Which of these other scientists (i.e., not Darwin) highlighted in the lecture OR on the Evolutionary Scientists Today, Bio Anth Edition page did you find most surprising or intriguing? Why?    #2: Evolution is not a mystery. We have observed many examples of populations changing over time both in the lab and in the wild. Which of these examples of Natural Selection in Action helped you understand how natural selection works the most? Why?

A few years later, other scientists discover a similar fossil (Fossil B) in a layer of sedimentary rock closer to Earth's surface. Fossil A and Fossil B share some characteristics, but it is determined that they are not closely related and that Fossil B is a different species. One hundred years later, scientists discover another similar fossil (Fossil C) in a layer of sedimentary rock between those in which Fossils A and B were found. Upon examining all three fossils, scientists reach the conclusion that all three fossils represent the same species.

Please answer fast

Please help with the following prompt using as much details as possible. "One argument that is often made to invalidate evolution by natural selection is that some features of an organism are so complicated and need to work together in order to precisely function that it is impossible for such structures to arise from simpler ones by the random processes of mutation and selection: complicated design requires a designer. Using evidence from real organisms, explain how a complicated structure can arise from a simpler ancestral feature. You can use either an anatomical feature or molecular one."

During and after the Industrial Revolution, the color of the moths gradually changed from predominantly light-colored to black. What caused this change? Select one: O a. Black moths were able to camouflage themselves on the trees that had soot on the bark, but white moths were eaten more by predators because they were not camouflaged. O b. The bad pollution killed all of the white moths because they were not as strong as the black moths. c. Black moths grew stronger and ate all of the white moths, so the white moth population decreased. O d. Black moths ate all of the pale lichens, so the…
