BioBeyond Lesson 3- Galapagos Exploration | 60 Questions with 100% Correct Answers | Updated & Verified Which of the following statements about the Galapagos are true? - ✔✔️T️he Galapagos are a group of islands in the Pacific Ocean. For much of their history, the Galapagos Islands were not significantly influenced by human interaction Select some of the creatures you'd find in the Galapagos. - ✔✔️e️verything but monkey observations - ✔✔️t️hey have a unique shell. their population is in critical condition. Often has a white body and eats marine life. It lives in dry forest. It eats the eggs of seas birds and flesh of dead animals. observations - ✔✔️l️ive near the slopes of volcanoes and have a unique shell. Lives off the coast and eats marine organisms. Only eats fruits and fetuses, eggs, and baby turtles. Observation pt. 3 - ✔✔️A️n endangered species because of the destruction of their nests. Preys on squid and fish. It also is found on the eastern island. Gathers energy by eating berries and crickets. Only found in the Galapagos. ✔✔️I️ think these factors caused a difference because the animals had to adapt to things in order to survive. Read the info icons and select which of the cases below shows two different species. Select all that apply. - ✔✔️l️ion Page 1 of 9 cricket View the images below to see if the boobies on the different islands are different species. - ✔✔️Y️es, they are different species because they do not mate with each other. Which of the following best describes the beak size of the finches on Daphne Major? - ✔✔️M️ost have average-sized beaks (Around 10mm). Your challenge is to create a population of finches where 80% have large beaks (greater than 10mm) in less than 100 generations. - ✔✔️d️rought Does changing the average rainfall on the island seem to have an effect on the traits of the population? What trait is being affected by the change in rainfall? - ✔✔️y️es beak size Which statement best explains why lower rainfall favors finches with larger beaks? - ✔✔️L️arge-beaked finches are able to eat the large seeds that are more common in times of drought (little rainfall). Select which graph shows the beak size of finches (shown on the x-axis) getting larger over time. - ✔✔️f️irst graph Which of following best describes directional selection: - ✔✔️O️ne direction or extreme of the trait is favored (very large OR very small beak-depths). Which of the following demonstrates descent with modification? - ✔✔️T️wo purebred red ladybugs give birth to a white lady bug Select all of the following that are true. - ✔✔️T️he individual finches cannot change their beak size. Page 2 of 9 Select which of the following is/are example(s) of sexual selection. Click on each of the letters to read more about each image. - ✔✔️b️ird and elk ✔✔️S️exual Selection:1. Bright colors of male ducks attract potential mates Natural Selection:1. The pale soil of Nebraska makes darker deer mice more easily visible to predators.2. After the short plant died due to infection, only tall deer could reach the higher plant Artificial Selection:1. Kale was created from a wild mustard plant after years of selective breeding2. After years of selection, wild boars have become pigs raised by many farmers today Find out how you can use sexual selection to create a population where 80% of finches have large bodies in 30 generations. - ✔✔️v️ery selective mate preference Predict how increasing the rate of predation will affect the population of finches. - ✔✔️I️t will speed up trait shifts. What is the most effective way to make the population of finches go extinct on the Island? - ✔✔️P️redation Rate:Increase Rainfall:No effect Mate Preference:No effect Was your hypothesis about increasing the predation rate correct? You said: "It will speed up trait shifts." - ✔✔️Y️es, the outcomes in my simulation support my hypothesis. In this challenge, try to keep the population of finches on the island of Santa Cruz a single species for 60 generations. - ✔✔️d️ont move anything just play it Increasing the pressure of natural selection such as rainfall or predation rate. Page 5 of 9 Increasing the pressure of sexual selection or mate preference. - ✔✔️S️peed up trait shifts/speciation for both In all the cases where you have created a new species the process followed a particular pattern. Complete the diagram below showing the process leading up to speciation. - ✔✔️F️rom top to bottom only first three words One population exist 2 .natural selection next to the sexual selection A shift occurs Some organism are no longer attracted Organism no longer mate SPECIATION challenge 5 - ✔✔️m️ess with each one by itself one by one then put insects on plentiful put cactus on plentiful and play What did you do to create a new species? - ✔✔️N️umber of cacti= increase Number of insects= increase Temperature= did not change Select which graph shows the change in the population of finches over time. - ✔✔️3️ Which of following best describes disruptive selection? Check all that apply. - ✔✔️T️he average version of the trait is not favored. Both extremes of the trait are favored (very large AND very small beaks). table - ✔✔️F️irst arrow:small beak bird mushrooms Page 6 of 9 Second arrow:large beak bird cactus Which birds are favored by the introduction of cacti and insects on the island? Check all that apply. - ✔✔️T️he large-beaked finches The small-beaked finches sort - ✔✔️1️. all fish have yellow color 2. by chance a number of offsprings 3. blue bodied fish choose to mate 4.After generation of sexual selections 5.blue fish can no longer mate with yellow fish 6.END SYMPATRIC What is the divide isolating the bird population on Isabela - ✔✔️C️. A mountain range What do you predict will happen once a mountain range separates two populations of this bird? - ✔✔️T️he birds will develop new traits to become adapted to their new environments. Which best summarizes what happened to the traits on each side of the island after 100 generations? - ✔✔️B️eak depth changes from average size to favoring large beaks on one side and small beaks on the other side of the island. Was your hypothesis regarding the traits of the birds after separation supported by your observations? You said: " The birds will develop new traits to become adapted to their new environments." - ✔✔️y️es Page 7 of 9
