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...

1. Which of the following properties of HIV makes it difficult to trace the source of the virus from one person to the next? a. The transmission of the virus involves very few (often just one) viral particles. b. HIV evolves very slowly within the host. c. The host can have a genetically diverse population of viruses. d. Molecular phylogenies of viruses cannot be constructed. e. None of the above Answer: c Textbook Reference: 22.0 Phylogenetic trees in the courtroom Page: 464 Bloom’s ...

Evolution - The change in allele frequencies in a population over time Selection - Changes in allele frequencies due to organisms with advantageous alleles reproducing more successfully than organisms with other alleles Genetic Drift - Random changes in allele frequencies in a population Mutation - The source of all new allelic diversity Migration - Movement of alleles between populations Adaptation - A trait that evolves by selection for a particular function (because it increases fitness...

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...

1. List the characteristics that all living organisms have; describe how biologists distinguish living organisms from non-living entities. Characteristics of all living organisms: ● Has potential to reproduce ● Responds to environmental stimuli ● Composed of 1 or more cells ● Contain genetic material (DNA) and can replicate their genetic material ● Made up of organic molecules (contain C) and water based ● Populations of this entity evolve ● Obtain energy and materials fro...
