The difference in heterozygosity for most loci among populations in North America, Central America and South America for a species of sparrow that originally lived only in Alaska but recently expanded its range through North America, Central America and finally South America. Introduction: Heterozygosity refers to the presence of separate alleles of genes at a particular locus. Greater the heterozygosity, greater is the genetic variation . The frequency of alleles of a gene in a population is affected by the genetic drift. Genetic drift, along with natural selection, leads to evolution and adaptation of the organism to the foreign environment.

Summary Introduction

To determine: The difference in heterozygosity for most loci among populations in North America, Central America and South America for a species of sparrow that originally lived only in Alaska but recently expanded its range through North America, Central America and finally South America.

Introduction: Heterozygosity refers to the presence of separate alleles of genes at a particular locus. Greater the heterozygosity, greater is the genetic variation. The frequency of alleles of a gene in a population is affected by the genetic drift. Genetic drift, along with natural selection, leads to evolution and adaptation of the organism to the foreign environment.

Summary Introduction

To determine: The regions out of North America, Central America and South America that are expected to have the most genetically similar populations and those that are expected to have the most genetically dissimilar populations.

Introduction: Genetic drift, along with natural selection, leads to evolution and adaptation of the organism to the foreign environment. Changes in the natural environment of an organism require them to adapt to the changes for greater chances of survival and adaptation. These changes are seen in the development of mutations over many years. They accumulate and cause the genetic drift of the organism.

9. Aerobic respiration of one lipid molecule. The lipid is composed of one glycerol molecule connected to two fatty acid tails. One fatty acid is 12 carbons long and the other fatty acid is 18 carbons long in the figure below. Use the information below to determine how much ATP will be produced from the glycerol part of the lipid. Then, in part B, determine how much ATP is produced from the 2 fatty acids of the lipid. Finally put the NADH and ATP yields together from the glycerol and fatty acids (part A and B) to determine your total number of ATP produced per lipid. Assume no other carbon source is available. 18 carbons fatty acids 12 carbons 9 glycerol A. Glycerol is broken down to glyceraldehyde 3-phosphate, a glycolysis intermediate via the following pathway shown in the figure below. Notice this process costs one ATP but generates one FADH2. Continue generating ATP with glyceraldehyde-3-phosphate using the standard pathway and aerobic respiration. glycerol glycerol-3- phosphate…

Normal dive (for diving humans) normal breathing dive normal breathing Oz level CO2 level urgent need to breathe Oz blackout zone high CO2 triggers breathing 6. This diagram shows rates of oxygen depletion and carbon dioxide accumulation in the blood in relation to the levels needed to maintain consciousness and trigger the urgent need to breathe in diving humans. How might the location and slope of the O₂ line differ for diving marine mammals such as whales and dolphins? • How might the location and slope of the CO₂ line differ for diving marine mammals such as whales and dolphins? • • Draw in predicted lines for O2 and CO2, based on your reasoning above. How might the location of the Urgent Need to Breathe line and the O2 Blackout Zone line differ for diving marine mammals? What physiological mechanisms account for each of these differences, resulting in the ability of marine mammals to stay submerged for long periods of time?
