    Chapter 6 Explain what free energy is and how it can be used to predict the energetic outcome of chemical reactions.Free energy is defined as the energy available to do work in any system. The free energy is denoted by the symbol G. G = H – TS* H: the energy contained in a molecule’s chemical bonds‚ called enthalpy.* TS: the energy term related to the degree of disorder in the system. T is the absolute temperature (K)‚ and S is the entropy.We can use the change in free energy to predict whether

  • Gould's Five Adaptationist Programme

    common view of evolutionary reasoning to date. The first adaptationist programme Gould mentions in the paper is a population that does not undergo selection or adaptation. In this type of population it is possible for the alleles to differentiate and then fix for different alleles. The next adaptationist programme mentioned in Gould’s paper is the method that observes an organism as a “whole ” instead of breaking down them down into separate traits. This type of programme was beneficial in that it

    Explain how you made your conclusion using evidence from the pedigree and the principles of genetics. -Cystic fibrosis is inherited as a recessive trait. Each child of 2 carriers has a ¼ chance of inheriting 2 recessive alleles. A person with 2copies of this allele has cystic fibrosis. 2. What would a Punnett square that shows how the son in generation IV (marked with an A) inherited cystic fibrosis look like? | |A |a | |A |AA

    carried the B allele‚ while those produced by the albino parent carried the b allele. The F1 offspring of such a cross would be Bb‚ and since black is dominant over albino‚ all the F1 animals would have had black fur. +1 point Second Cross: Since some of the F1 offspring are albino‚ that means that the black parent must have been heterozygous for fur color. So‚ the parents of the second cross were Bb x bb. The black parent would have produced gametes carrying either the B or the b allele‚ while the

  • Gregor Mendel, a Roman Catholic Monk

    A Roman Catholic monk‚ Gregor Mendel (1822-1884)‚ was raised on a farm and enjoyed gardening and mathematics. In 1856 he started to experiment with pea plants to explain why certain traits that appeared in one generation did not always reappear in the next generation. During eight years Mendel mixed over 30‚000 plants by controlling their pollination and wanted to know why the results came to be. Mendel noticed that although there were some traits that were common amongst all the pea plants there

  • Determining the Unknown Genotype of Corn Plants of the Zea Mays Species from the Phenotypes of Offspring Produced

    Scientific Paper 4-10-13 Determining the Unknown Genotype of Corn Plants of the Zea mays Species from the Phenotypes of Offspring Produced Abstract No one particular organism is an exact replica of another. Diversity in the world is key for future generations to adapt to the fast changing world. This lab observed the corn plant of the Zea mays species to determine the genotype for the gene of tall versus dwarf in unknown parent corn plants by observing the seedlings produced. It was hypothesized
