Ch 16 Multiple Choice Identify the letter of the choice that best completes the statement or answers the question. ____ 1. For a couple of decades, biologists knew the nucleus contained DNA and proteins. The prevailing opinion was that the genetic material was proteins, and not DNA. The reason for this belief was that proteins are more complex than DNA. This is because a. proteins have a greater variety of three-dimensional forms than does DNA. b. proteins have two different levels of structural organization; DNA has four. c. proteins are made of 20 amino acids and DNA is made of four nucleotides. d. Only A and C are correct. e. A, B, and C are correct. ____ 2. In his transformation experiments, Griffith observed that a.

Acclimatization - short-term, reversible responses to environmental fluctuations // phenotypic change in an individual in response to short-term changes in the natural environment. The ability to acclimatize is itself an adaptation. As an individual develops, the embryonic tissues give rise to four adult tissue types: 1. Connective tissue loose connective tissue - fibrous proteins in a soft matrix; serves as a packing material b/w organs or padding under the skin (ex: reticular connective tissue in lymphoid organs such as the spleen and bone marrow/ adipose tissue or fat tissue are loose connective tissues made up of cells suspended in a matrix of fibers and fluid) dense connective tissue - found in tendons and ligaments that connect muscles, bones,

The Evolution of Psychology Psychology is an ancient art ?psyche? = soul ?logos? = study of a subject And a less ancient scientific discipline early 18th century - ?study of the mind? Multi-disciplinary approaches: Room for chemists, biologists, physiologists, sociologists, anthropologists, evolutionary everythingists, etc. Intellectual parents - philosophy and physiology And Wilheim Wundt, the godfather United all the different questions under one common mystery umbrella 1870 - first lab founded in University of Leipzig The Early Growth Phase Thanks to Wundt, started off on a good science foot. Scientific study of conscious experience: Attention Sensation and perception Reaction time etc.

Alkenes are commonly described as unsaturated hydrocarbons because they have the capacity to react with substances that add to them. Alkanes, on the other hand, are saturated hydrocarbons and are incapable of undergoing addition reactions. 6.1 Hydrogenation of Alkenes The relationship between reactants and products in addition reactions can be illustrated by the hydrogenation of alkenes to yield alkanes. Hydrogenation is the addition of H 2 to a multiple bond, as illustrated in the conversion of ethylene to ethane. The reaction is exothermic and is characterized by a negative sign for ?H?. Indeed, hydrogenation of all alkenes is exothermic. The heat given off is called the heat of hydrogenation and cited without a sign. In other words, heat of hydrogenation = -?H?.

Alcohols and Alkyl Halides: Introduction to Reaction Mechanisms In this chapter we explore structure and reactivity in more detail by developing two concepts: functional groups and reaction mechanisms. A functional group is the atom or group in a molecule most responsible for the reaction the compound undergoes under a prescribed set of conditions. How the structure of the reactant is transformed to that of the product is what we mean by the reaction mechanism. 4.1 Functional Groups Table 4.1 lists the major families of organic compounds covered in this text and their functional groups. 4.2 IUPAC Nomenclature of Alkyl Halides The IUPAC rules permit alkyl halides to be named in two different ways, called functional class
