focus on chemical signals. 1. External signals are converted to responses within the cell a. Evolution of cell signaling i. In yeast a cells and αcells both secrete chemicals‚ which can only be received by the alternate type yeast. This signals the two cells to join via fusion 1. The process by which the signal on the surface of the cell is converted to a series of steps by the cell in response is called a signal transduction pathway ii. Signal transduction

AP Biology Name: Chapter 51 Guided Reading 1. How do behavioral ecologists define behavior? Behavioral ecologists define behavior as everything an animal does and how it does it 2. What is the focus of: a. Proximate questions of behavior? Focuses on the environmental stimuli‚ if any‚ that trigger a particular behavioral act‚ as well as the genetic‚ physiological‚ and anatomical mechanisms underlying it. b. Ultimate questions of behavior? Focuses on the evolutionary significance

Pre-lab questions: 1. Algae belong to what Kingdom? They belong to the Kingdom Protista. 2. What are the three types of multicellular algae? The three types if multicellular algae are chlorophyta which are green algae‚ phaeophyta which are brown algae‚ and rhodophyta which are red algae. 3. Are algae autotrophs or heterotrophs? Algae are autotrophs. 4. What organelle allows plants (and plantlike protists) to photosynthesize? The chloroplasts allow plants and plantlike protists to photosynthesize

Hannah Bunker Mr. La Plante AP® English Language and Composition Fourth Hour 24 January 2017 Extended Response I: Reading with a Critical Eye Books are precious pieces that improve one’s knowledge and help define one’s personality by relating themselves to characters within the text. As Vladimir Nabokov said in Good Readers and Good Writers “The reader should identify himself or herself with the hero or heroine.”(Nabokov‚ 973) I always believed that by reading a book you become

AP Biology Sunday‚ October 24‚ 2010 Enzyme Lab Write-Up Purpose: To observe how an enzyme affect the speed of chemical reaction. To describe how the concentration of an enzyme affects its ability to work. Hypothesis: Depending on the concentration of the catalase which the disk is soaked in‚ it will have a direct correlation on the rate of hydrogen peroxide being broken down into oxygen gas. Prediction: Since the rate of reaction can be lowered by the addition of

reflection on human behavior. First I will talk about genetics‚ also referred to as heredity. Then I will speak on hormones. Also in this essay I will discuss the endocrine system‚ identification of hormones and the glands responsible for secreting them‚ and genetics‚ behavior genetics‚ and evolutionary psychology. Hereditary To compare heredity effect on behavior you have to start with the old question is it nature or nurture? The importance of nature versus nature is simply your belief

potential" (Ψ) is a measure of the free energy of water; pure water (which has a high amount of free energy) is arbitrarily assigned a water potential of zero; units pressure: MPa; can be positive or negative factors that determine plant water potential: 1) amount of solutes- increasing concentrations will lower the free energy (water potential); termed osmotic potential (ψs) 2) turgor pressure (ψp) in plant cell- positive pressure inside plant cells; increases free energy; loss of turgor = wilting
