Chapter 2 IB Biology 2.1 Cell Theory 2.1.1 Outline the cell theory (2). • All organisms are composed of one or more cells • Cells are the smallest units of life • All cells come from preexisting cells • TOK: cell theory replaces the former ideas of spontaneous generation or abiogenesis in which inanimate matter assembles itself into living forms • Exception: muscle cells- more than 1 nucleus‚ very long; (fungal cells) hyphae roots- not a single unit; protoctista- not specialized to single

based on service and rapid response to customer needs. While product diversity within a paperboard plant would not be apparent to a casual observer‚ subtle differences exist. For example‚ paperboard differs by basis weight (thickness determined by caliper measurements) for a specified length of product. Additionally‚ paperboard may be uncoated or coated with an opaque‚ white clay-based material that masks cosmetic flaws and smooths surface variability. Customers are increasingly concerned with surface

Student Handout Response Sheet: Used with Lab 5 Activity #2 Question Set (The Structure & Function of GeneChip Microarrays) Directions: The following questions go with Activity #2 reading on the structure and function of GeneChip microarrays. Answer each question as thoroughly and detailed as possible. Part I – Intro‚ and Gene Expression Microarrays (1) What is gene expression? What can affect gene expression? • When a gene is used to build an mRNA copy (transcription) which is then

and how the type of fracture for this specimen. All of this issue‚ we had been discussed more details in our discussion. In this experiment we used a tensile testing machine to elongate the specimen but we drive it manually‚ we also use a vernier caliper to measure a length of elongation of the specimen and this experiment we carrying according to procedure given. Finally‚ at the conclusion we were strictly restated our stand about the result of this experiment which were value of modulus elasticity

1) The importance of using hand tools Use the Right Tool for the Job Using the correct tool for the job is the first step in safe hand tool use. Tools are designed for specific needs. That’s why you’ll find screwdrivers with various lengths and tip styles and pliers with different head shapes. Using any tool inappropriately is a step in the wrong direction. To avoid personal injury and tool damage‚ select the proper tool to do the job well and safely. Quality professional hand tools will last

cells. Cell Shape: There are over 200 different types of cells within the human body. These cells all vary in size‚ shape and diameter. Most cells range between ten and fifteen micrometers in diameter‚ however‚ some cells‚ such as the human egg cell‚ are much larger than this‚ with a diameter of roughly 100 micrometers. The human eggs cell is just barely visible to the naked eye. Some of the longest cells include nerve cells‚ which can be as long as a meter‚ but are so thin; they are invisible to
