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

Asexual Reproduction in Animals Group 3 Nina Bansil Kenneth Calabia Josef Franz Cruz I. Introduction Asexual reproduction is reproduction which does not involve meiosis‚ ploidy reduction‚ or fertilization. Only one parent is involved in asexual reproduction. A more stringent definition is agamogenesis which refers to reproduction without the fusion of gametes. Asexual reproduction is the primary form of reproduction for single-celled organisms such as the archaea‚ bacteria‚ and protists

Chapter 1: Intro Independent Variable - variable you deliberately change during an experiment Theory - explanation based on a large number of experiments Hypothesis - educated prediction of cause and effect - what you test in an experiment Control - a zero or set form of the independent variable Dependent - variable you measure because you think it could change 7 characteristics: order‚ regulation‚ growth and development‚ energy processing‚ response to the environment‚ reproduction‚ evolutionary

Microscopy‚ Cell Structure and Function Task 2 I: Name and describe the four main types of tissues in animals stating their functions and their location in the body give two examples of each type. The four main types of tissues that you will find in eukaryotes are connective‚ muscle‚ nervous and epithelial tissues; each of which having very different roles. Connective Tissue The first tissue type I am going to look at is the connective tissue. This tissue is found all over the body‚ including

Unit 3 Lecture Study Guide 1. List the 4 primary tissue types and give the general characteristics and functions of each one. 1) Epithelial: Covers the body‚ lines the cavities‚ tubes ducts and blood vessels‚ covers the organ inside the body cavity 2) Connective: most abundant& widely distributed‚ connect‚ bind and supports structures‚ insulates‚ and transports substances. 3) Muscle: associated with the bones of the skeleton‚ the heart and in the walls of the hollow organs

environment. 4. The four organic macromolecule groups common to all living things are carbohydrates‚ proteins‚ nucleic acids‚ and fats. 5. All living things are composed of one or more cells. 6. Humans are unicellular creatures. 7. Mitosis is cell Xeroxing that occurs in prokaryotic cells. 8. Homeostasis is the process of maintaining a dynamic equilibrium of factors within which living things can exist. 9. Of the cellular metabolic processes‚ Glycolysis is the only one that

LIVING THINGS * All living things come from other living things. * Ex: One single celled organism to another * DNA is copied & passed to offspring * The signature molecule of life * Ex: embryo- cells continually divide & develop EVOLUTION * Why do some organisms seem suited for their environment * Ex: Hummingbird- long beak for nectar in certain flowers * Ex: Cheetahs- take down faster prey * Adaptation- inherited characteristic that

North Facing Side (NFS). This extreme sun exposure causes the South slope to have drought and arid conditions whereas the North side has more temperate conditions and is shady and humid. The model‚ Sordaria fimicola‚ reproduces through the process of Meiosis and their chromosomes cross over in Prophase I (Stern). S. fimicola have different crossover frequencies between the slopes in Evolution Canyon; there are higher crossover frequencies on the SFS compared to the NFS. One possible explanation of this

DNA is the most important for life One of the most complex and mysterious aspects of contemporary science is the constitution of life. While it goes without saying there are an enormous amount of components that collaborate to achieve the most effective and efficient components of life‚ it’s also clear that some of these molecular components contribute to the actual function of living system more than others. This essay argues the DNA is the most important molecule for life. Deoxyribonucleic
