Name Period Chapter 7: Membrane Structure and Function Concept 7.1 Cellular membranes are fluid mosaics of lipids and proteins 1. The large molecules of all living things fall into just four main classes. Name them. Explain what is meant when we say a molecule is amphipathic. 3. In the 1960s‚ the Davson-Danielli model of membrane structure was widely accepted. Describe this model and then cite two lines of evidence that were inconsistent with it. 4

LAB 1 1. Describe the function of the following pieces of safety equipment and how each might be used: (10 points) a. Eye Wash (2 points) In the event of a chemical splash to the eyes‚ flood the eyes for at least 15-30 minutes with water. Flush from the eye outward. If you were not wearing proper eye wear‚ a chemical could splash into your eye and would make it necessary to use this. b. Fire Blanket (2 points) Used in order to put out a small fire. If a small area of the lab caught

2 September 2014 Chapter 1 Review 1. Describe the characteristics of science. A. The characteristics of science are observations‚ search for regularities‚ process the information‚ and self-corrections. Science is based upon observations that incorporate our senses‚ or instruments that extend our senses‚ to interpret natural experiences. Science is a searh for regularities. These regularities may include observed phenomena or patterns in nature. After observations have been recorded about regularities

Meghann Kiphart AP Biology Lab Report Number One Mrs. Irvine Introduction: Because all molecules have kinetic energy and are constantly in motion cells go through a process called diffusion. Diffusion is the movement if molecules from an area of higher concentration to and area of lower concentration. This process with continue to occur until an equilibrium is reached. Osmosis is a different and unique kind of diffusion. Osmosis is the diffusion of

Lab 1 : Scientific Method 20 Table 2: Water quality vs. fish population 1. Based on the information in Table 2‚ (in the lab manual) what patterns do you observe? 2. Develop a hypothesis relating to the amount of dissolved oxygen measured in the water sample and the number of fish observed in the body of water. 3. What would your experimental approach be to test this hypothesis? 4. What are the independent and dependent variables? 5. What would be your control? 6. What type of graph would

To understand that the lungs do not contain muscle and that respirations are therefore caused by external forces. To explore the effect of changing airway resistance on breathing. To study the effect of surfactant on lung function. To examine the factors that cause lung collapse. To understand the effects of

Show your work‚ use your own words and cite all references. 1. (20 points) The HeLa S3 cancer cell line is considered to be “continuous” due to acquired mutations that enable the cells to evade senescence. This property is one of several hallmark characteristics of cancer cell lines. Describe three hallmark characteristics

Ksenia Semina Evolution Lab ARR 3 Blast Lab Analysis: Gene 1: The 4 organisms that were looked at in the Gene 1 are bird‚ vertebrate‚ rodent and bony fish. From the Blast result the most similar gene sequence to the gene of the gene of interest is Gallus gallus collaged which is also a bird. They are the most similar because the Gallus has the highest max score out of all other genes and 100% for the ident and there is no difference in the e-value. The species is located at the bird’s branch

The process of deriving the new drug starts in the laboratory. The chemical formula of the drug are composed in the lab and also called as the vitro testing. This type of testing performed before the drug can be tested on the animals or humans. The vitro testing gives the chemical description of the new drug and formulates the base and additional supplements. After vitro testing is done‚ the vivo testing starts on the animals. This process includes testing to figure out the possible side effects
