Genome sequences of seven well-studied ant species give researchers a detailed look at molecular mechanisms - including what may be a basis for complex behavioral differences in two worker castes in the Florida carpenter ant‚ Camponotus floridanus - basically‚ epigenetics. Epigenetics is the study of how the expression or suppression of particular genes by chemical modifications affects an organism’s physical characteristics‚ development‚ and behavior; if that sounds vague or perhaps even Lamarckian

AP Psychology Midterm Study Guide #1 Unit 1: Psychology’s History and Approaches 1.Definition of Psychology? Disciplines it is rooted in? Psychology is the science of behavior and mental process; it seeks to answer how and why we think‚ feel‚ act as we do. Psychology is rooted in philosophy and biology. 2.What is the difference between nativism and empiricism? Which ancient philosophers/early psychologist were nativist? which were empiricist? Nativism is the argument that all our skills

Interactions BigIdea 4 investigation 13 ENZYME ACTIVITY* How do abiotic or biotic factors influence the rates of enzymatic reactions? ■■BACKGROUND Enzymes speed up chemical reactions by lowering activation energy (that is‚ the energy needed for a reaction to begin). In every chemical reaction‚ the starting materials (the substrate(s) in the case of enzymes) can take many different paths to forming products. For each path‚ there is an intermediate or transitional product between reactants and

Ethanol on Fermentation Rates In this lab we examined how the rate of fermentation is influenced by the type of substrate‚ and activators and inhibitors. We used four fermentation tubes in which we separately combined yeast with MgSO4‚ pyruvate‚ ethanol‚ and glucose. At five minute intervals we recorded the volume of gas produced in each fermentation tube. Our results are displayed in the graph. Our results supported the prediction that pyruvate is an activator of fermentation. But our

Hannah Baumann Bio 212 Lab: Thurs 10:00 Transpiration Laboratory Abstract: Transpiration is affected by many things including temperature and humidity; we were interested in seeing what other factors influence the rate that transpiration occurs. The purpose of this experiment was to explore how paint effects transpiration. I hypothesized that the rate of transpiration would decrease with the addition of paint to the bottom or the Laurel twig’s leaves. After collecting and analyzing the

proposed to produce vitamin C efficiently such as Reichstein Process‚ TwoStep Fermentation Process and Single Step Fermentation Process. The most common methods used are Reichstein Process and Two-Step Fermentation Process. The first method used is the classical Reichstein process back in the 30s. This process was introduced by Tadeus Reichstein and his collegues in 1935 [1]. The Reichstein process uses a single pre-fermentation process followed by a purely chemical route which involves five steps.

was to investigate the effect that a glucose concentration has on the rate of fermentation. This was done by adding a variety of different glucose concentration into a test tube‚ siting in a water bath. The carbon dioxide would be collected in the test tube and therefore would measure the rate of fermentation. The results parsley supported the hypothesis that‚ “If the glucose concentration increases‚ the rate of fermentation increases‚ therefore the more carbon dioxide released”. Background All cells
