QUESTION 3 Darwin's theory of natural selection explains: O The way life began. O The way evolution works at the genetic level. The way dinosaurs became extinct. O That traits within a breeding population that are adaptive to specific environmental circumstances become more numerous in that population over time.

Enlarge Image 100 Mutation causes variation Conditions do not favor some mutations Survivors reproduce Change in conditions do not favor some traits Survivors reproduce 1) This model shows the process of natural selection on rabbits demonstrating variation in fur color over several generations. Using the model, what most likely led to the loss of white furred rabbits in the population? A) XB) C) The white rabbits did not reproduce fast enough to survive. White was a recessive trait and therefore not passed on to any offspring. The white fur was a favorable trait but was never prevalent in the population. The rabbits with white fur had less camouflage in D) the environment and were more easily preyed on by predators. 2) If this model continues, with no major changes to the environment, what do you expect to happen? XA) Rabbits will continue to get lighter over time.

2020 Online Discussion B. Darwin's Theory Warm-Up Active Developing the Theory of Evolution WARM-UP What was Charles Darwin's contribution to the theory of evolution? O Charles Darwin was the first to express the belief that all living things are related. Charles Darwin believed that organisms had a goal to adapt and did so through the inheritance of acquired traits. Charles Darwin introduced the idea that organisms better adapted to their environment would tend to survive, reproduce, and increase in number. Charles Darwin developed the theory of population growth. DONE O Intro Activity DII 96 2, or go

Question 23 What is the MOST LIKELY explanation for why there is variation in aging across different species? O The strength of selection is determined by aging O Trade-offs only apply to some species O Mutation accumulation theory applies to some species while antagonistic pleiotropy applies to others O Different species suffer different levels of background (i.e., extrinsic) mortality

Revise the passage Darwin is best known for his Theory of Inheritance of Acquired Characteristics, first presented in 1801 (Darwin's first book dealing with natural selection was published in 1859):Based on these observations and inferences, Darwin concluded that these traits, called adaptations were the product of evolution by Acquired Traits, these traits made the members of the population who had them equally fit for survival. an organism could also change during their lifetime in order to adapt to its environment, those changes are passed on to its offspring. For example, darwin believed that if giraffes stretched their necks to reach food, Their offspring and later generations would inherit the resulting long necks.

17 The graph below represents the number of brown and green beetles collected in a particular ecosystem. Change in Coloration of Beetle Population Green beetles Brown beetles Time (years) The change observed in the number of green and brown beetles in the population is most likely due to (1) natural selection (2) selective breeding (3) gene manipulation (4) a common ancestor [4] Number of Individuals

Hello, I need help answering number 35(INCLUDING THE SUB-PARTS) multiple choice questions. Pls and thank you! 35. A.) The significance of genetic polymorphism in evolution relies on the fact that: a) such genetic polymorphisms do not change over time b) without genetic differences, natural selection cannot cause evolution c) phenotypic polymorphism is always the same as genetic polymorphism d) inbreeding increases the amount of genetic polymorphism in a population   B.) Stabilizing natural selection can occur when: a) the mean phenotype is evolving to track a changing environment b) the population is already at a peak on the adaptive landscape c) the population is adapting to two different ecological niches d) the selection differential is positive   C.) Evidence that Homo sapiens originated in Africa includes: a) the highest heterozygosity per locus is found in East Asia b) populations in Africa show evidence of founder effects c) populations in Oceania and South America are quite…

Please help with Evolution Bio problem please quick! A flock of 300 Red Legged Jabberwockys gets blown off course during a storm and ends up taking refuge on an island several hundred miles offshore. All 300 members of the Jabberwocky flock have the genotype BB1 for the B locus. On the island where this lost flock lands, the resident population of Red Legged Jabberwockys consists of 700 individuals, all of which have genotype B2B2 for the B locus. Given this information, calculate the observed allele frequencies of the combined population on the island, and the expected genotype frequencies of the next generation. Observed allele frequencies of current generation: (express answers in 1 significant digit: 0.0) p = B1 = q = B2 = Expected genotype frequencies of the next generation: (express answers in 2 significant digits: 0.00) B1B1 = B1B2 = B2B2 = Has migration increased or decreased genetic variation in the island population? Assuming natural selection favors the Be allele in the…

Question zo Multiple Choice Which of the following statements BEST describes Population Genetics? The analysis of fossits from different strata, to understand how "intermediate forms" can represent common ancestors between species. The study of the evolution of living populations by looking at how the frequency, distribution, and inheritance of alleles changes over many generations. The field of biology that deals with the naming, identifying, and classifying of species, to understand how different populations are evolutionarily linked. The comparison of embryonic development in different species to understand ascertain how closely two species are related.

Question- How is genetic drift different from natural selection? choose one from below 1. Natural selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error  2. natural selection has a stronger effect in large populations, whereas genetic drift acts primarily in small populations 3. natural selection is a mechanisms of evolution, whereas genetic drift is not a mechanisms but an outcome of evolution 4. natural selection tends to cause very rapid evolution, whereas genetic drift tends to operate on much longer time scales.

Hello, I need help answering number 20(including the sub-parts). Pls and thank you  20. A.)T / F Both negative frequency-dependent selection and positive frequency-dependent selection act to maintain genetic polymorphism. B.) T / F The mass extinction at the end of the Cretaceous caused the extinction of all non-avian dinosaurs. C.) T / F Natural selection can occur without any evolution in the next generation if individual differences in the trait are not heritable.

Directions: Perform the task below based on your understanding on the topic " Mechanisms 'of Evolutionary Change" . There are four factors that can change the allele frequencies of a population namely Natural Selection, Mutations, Genetic Drift and Gene Flow. Make a creative outline summarizing the processes happened in these mechanisms of evolutionary change (use separate sheet if
