Why is the scientific method bad? - Answer-It is oversimplified, it implies that an experiment can answer a research question. Science isn't linear. It implies science is an independent effort, no creativity or imagination, and it ignores technology and society What is a theory? - Answer-Theories are broad explanations. They are supported by lines o evidence, with no contradictory evidence. Therefore the evolutionary theory isn't just a "theory" Why don't community analysis and feedbac...

McMaster Bio 1M03: Exam Questions and Answers A, Guide Why might Pasteur's experiment be inconclusive? The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? To ensure that results were not achieved by random chance What is the definition of a replicate? Unit that shares a common thing (4 mice in one cage = 1 replicate) What ...

change from gen to gen via selection of heritable traits evidence for evolution - Answer - fossils - extinction - transitional forms - vestigial traits why is the myth about evolution being goal oriented false? - Answer species do not adapt because they "want" or "need" traits; they adapt them because an ancestor with that triat just so happened to reproduce sooner or more successfully than others why is the myth that evolution is a hierachy false? - Answer evolution is more a ne...

BIO 117 Exam 1 Questions and Answers 100% Pass What is an adaptation? - Correct Answer ️️ -a trait that improves the fitness of its bearer, compared with individuals without the trait How can biological fitness be estimated? - Correct Answer ️️ -Count the number of healthy, fertile offspring produced by different individuals in a population. All of the following are true for natural selection EXCEPT: - Variation exists in populations (all individuals are NOT the same). -Characteri...

convergent evolution - Answer the process by which organisms are not closely related, but independently evolve similar traits that help them adapt to similar environments evolution - Answer the process by which living organisms have developed and diversified from earlier forms during the history of the earth natural selection - Answer a process by which individuals with certain alleles produce the most surviving offspring in a population fitness - Answer the ability for an individual to...

Why might Pasteur's experiment be inconclusive? - Answer The swan-necked flask broth may not support cell growth, or the broth was poisoned. Experiment did not confirm hypothesis that all cells come from pre-existing cells Why are replicates important in experiments? - Answer To ensure that results were not achieved by random chance What is the definition of a replicate? - Answer Unit that shares a common thing (4 mice in one cage = 1 replicate) What does the law of succession suggest?...

We recommend doing that activity before trying this one.] Prior Knowledge Question (Do this BEFORE using the Gizmo.)

Two types of dispersal - Answer-active and passive What are the three ways species know how/when to disperse? - Answer-innate, learned or environmental cue response physical barriers - Answer-ocean, mountain Behavioural barriers - Answer-competition, zonation Anthropogenic barriers - Answer-human caused - roads, dams, poaching What is the most prominent thing preventing dispersal - Answer-Barriers range expansion - Answer-the idea that the geographic areas occupied by species change over ...

ASU BIO 182 Exam 2 Questions And Answers Head in the Clouds Giraffes are the tallest animals on land. An adult giraffe has a neck that exceeds 2 m in length. This neck enables a giraffe to access food that other animals cannot reach and detect predators from a long distance. Studies have shown that giraffes will browse trees at heights that other herbivores cannot reach. The water and nutrients gained from leaves enhance a giraffe's fitness by increasing survival and reproduction. Howev...

Life Science 15 Phelan Graded A+ Evolution ️A change in allele frequencies over time. Allele ️A variant form of a gene. Gene ️A segment of DNA that provides instructions for producing a trait. Natural Selection ️Involves variation, heritability, and differential reproductive success. Fitness ️The relative reproductive success of a genotype or phenotype. Four Agents of Evolution ️Natural selection, mutation, gene flow, genetic drift. Natural Selection ️Non-random elimination ...
