Microbe CORRECT ANSWER -Free living organisms so small that they are only visible under the microscope. -Viruses are not really microbes- they lack one key quality of living cells; the capacity to main their bodily integrity throughout their life cycle. -Exceptions: Epulopiscium fishelsoni is huge (600+ um), Mycobacterium leprae is not free living. -Bacteria, Archaea, Fungi, Protists. LUCA CORRECT ANSWER -Last Universal Common Ancestor= microbe -About 4 bya -Core features for cellular...

Honors Biology – Evolution Questions and Answers Graded A+ What is the significance of genetic drift in small populations? Genetic drift causes random changes in allele frequencies, which can significantly impact small populations. How does the concept of speciation relate to evolution? Speciation is the process by which new species arise from existing ones, contributing to evolutionary diversity. What role does sexual selection play in evolution? Sexual selection favors tr...

"Salting out" - certain ions become too concentrated in soils and draw water out of roots by osmosis, causing plant death 2 types of lateral meristems: - Cork cambium vascular cambium 2 ways to increase allele diversity/allele frequency distribution: - 1.) gene flow 2.) mutation 3 Chordate Subphyla - Urochordata, Cephalochordata, and Vertebrata 3 criteria for designating species: Boys Make Pasta - biological, morphological, phylogenetic 4 key characteristics of chordates - 1.) notochor...

Last Universal Common Ancestor (LUCA) CORRECT ANSWER Was a microbe of unknown type that lived about 4 billion years ago; the origin of all organisms. What is 16s small unit rRNA used for? CORRECT ANSWER It's used to study construct phylogenetic trees of organisms because it's highly conserved and hasn't changed much over time. Antonie von Leeuwenhoek CORRECT ANSWER Father of microscopy in 1620 Increased surface area like folded membranes CORRECT ANSWER How do larger cells maximize di...

One definition of evolution is that evolution is "descent with modification". What does "modification" refer to in this definition? (1) Mutation and (2) Sexual Mixing What is the only statement that is NOT true about the genetic relatedness of life on Earth? Gorillas are the closest living relative to humans All but one feature listed below are shared between family trees and phylogenetic trees. Represent populations on each branch Which of the following is the only TRUE statement abou...

Biology 1108 Final Exam Quiz Questions with 100% pass The term "n" refers to the size of a population, that is, the number of individuals in that population. In general, in a sample of n individuals, the frequency of an allele is: - Correct Answer ️️ -the number of occurrences of the allele divided by twice the number of individuals in the sample (2n) If a population is not in Hardy-Weinberg equilibrium, we can conclude that: - Correct Answer ️️ -evolution has occurred because on...
