AP BIOLOGY- Mitosis and Meiosis Cell Division Lab Part 1-MITOSIS summary: In this experiment first the stages of an onion cell undergoing mitosis are going to be observed and every stage is going to be detected and drawn on paper. A brief description to what is going on should be attached to the pictures. This is important to understand the basics of cell division which is necessary growth‚repair

* Biology Investigation 3.1 Porcellio Scaber (Slater‚ Woodlouse) Task 1 The crustacean Porcellio Scaber‚ or more commonly known as the woodlouse‚ is a species usually found in leaf litter or in fallen trees and bark. It feeds on detritus like many other isopods of its type‚ and is generally predated on by small mammals‚ lizards and some insects. The woodlouse habitat reflects its need to avoid warm and dry areas. The woodlouse is prone to desiccation (drying out) due to its body’s large surface

Biology Digestion IA 13/03/2013 Jason Gao Rationale: Digestion is the chemical breakdown of food into smaller components that are more easily absorbed. Digestion is a form of catabolism: a breakdown of large food molecules to smaller ones. When food enters into stomach‚ gastric juice starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. The pH value of hydrochloric in the stomach

Michelle Kim 2012.1.20 Biology Iso-osmolar Concentration of Carrot Cells Lab INTRODUCTION For a more thorough understanding of this lab introduction‚ the concepts of‚ iso osmolar‚ membrane‚ equilibrium‚ and concentration gradient evaluated. Iso osmolar can be known as the point in which the substance of experimentation faces no change despite the amount of solute inside the solvent( because the solvent and solute concentration is equal. This is where the line on a graph would cross on the

1. What is the purpose of science? The purpose of science is to understand. With science‚ we ask questions‚ seek answers‚ and prove or disprove our theories and speculations. According to the text on page 10 “Science is a way of knowing about the natural world.” (Citations will be provided at the end of the worksheet‚ rather than a continuous re-pasting each time.) 2. Define organism. Give an example of a unicellular organism. According to the text on page 3‚ “Organisms‚ such as trees and humans

Biology Assessment: Influenza Structure: Viruses are non-cellular obligate intracellular parasites‚ requiring a living host cell in order to reproduce. A developed viral particle (virion) lacks the metabolic machinery of cells‚ containing just a single type of nucleic acid (DNA or RNA) encased in a protein coat or capsid. Viruses can be distinguished by their structure and by the nature of their genetic material (single or double stranded DNA or RNA). Viruses that affect humans are more difficult
