McMaster Bio 1M03 Exam Verified A Score 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 does the law ...

Evolution Questions and Answers Already Graded A adaptive radiation (divergent evolution) process by which a single species or small group of species evolves into several different forms that live in different ways; rapid growth in the diversity of a group of organisms analogous structures is a trait or an organ that appears similar in two unrelated organisms anatomical homology similar body structures among different species from a common ancestor biogeography is the study of the distributio...

How does mutation lead to gene pools changing? - Answer alleles mutate into another form; important for variation How does natural selection lead to gene pools changing? - Answer not all individuals have ability to produce offspring; "survival of the fittest" How does non-random mating lead to gene pools changing? - Answer mating based on proximity and preference; not all individuals have equal chance of finding mate How does gene flow lead to gene pools changing? - Answer migration; los...

What are Darwin's three conditions for natural selection? 1) Heritable characters 2) Characters show variation between individuals 3) Differential fitness (= survival, reproduction) between individuals What is the definition of evolution? genetic change over time in a population Is all evolution caused by natural selection? no Is natural selection the only consistent force leading to adaptations? yes What types of evidence can be gathered for evolution? Fossil...

BIO 101 EXAM QUESTIONS AND CORRECT DETAILED ANSWERS What makes the "head" of a phospholipid hydrophilic? A) The even distribution of electrons across the fatty acids makes the head polar. B) The uneven distribution of electrons across the fatty acids makes the head polar. C) The phosphate group carries a negative charge, making the head polar. D) The phosphate group carries a negative charge, making the head nonpolar - ANSWER C Which would most likely pass unaided through a pla...

1. Darwin described evolution using the phrase "descent with modification." Please select the response that describes most accurately from a modern perspective what the phrase entails. A) Evolution takes a long time - it is a gradual process - and produces decent results. B) Evolution is a natural phenomenon that is ongoing, changing individuals even today. C) Closely related species are similar at the genetic, developmental, and structural levels. D) Populations living today are identi...
