What cellular events occur in the G1 phase of the cell division cycle? - ANSWER normal growth and cell function What is the best way to describe homologous chromosomes? - ANSWER they carry information for the same traits In some parts of Africa, the frequency of individuals who are heterozygous for the sickle-cell anemia allele is higher than the frequency in North America, presumably because this reduces the frequency of malaria. Such a relationship is related to what? - ANSWER Darwin's ...

What are the 2 theories of evolution? Explain each - correct answer Gradualism- geologic changes result from slow, gradual, continuous process Punctuated Equilibrium- Long period of stasis punctuated by short bursts of significant change. What was Lamarck's theory and why was it wrong? - correct answer Lamarck = Inheritance of Acquired characteristics- traits acquired during lifetime could be passed on What is natural selection - correct answer Comptetition for limited resources re...

Brooks Biological Principles Exam 3 Questions and Answers Mitosis - Answer- • the duplication and division of the nucleus • results in clones with *no* variation or adaptation • takes place in somatic cells (non-sex cells) • starts with one cell and creates 2 identical daughter cells • replicated chromosomes are evenly divided so that each daughter cell receives a complete set (46 chromosomes) • *can occur by itself*, but usually involves cytokinesis • not synonymous with ...

Which of the following is a true statement about a human zygote? correct answers This diploid cell contains all of the genetic information for the individual it will become. Which of the following sets of statements is true of a homologous pair of chromosomes? correct answers They have the same genes but unique alleles. One member of the pair is inherited from each parent. Can the expression of highly heritable traits, such as maze-running ability in rats, be influenced by environment? Why...
