The hypothesis for this lab was that Core B will be the least flexible due to a loss in water. Unfortunately‚ my results led my hypothesis to be incorrect. The results that were received was that Core C was the most flexible‚ Core B was somewhat flexible‚ and Core A was not flexible and stiff. Core A was the most non-adjustable due to it being hypertonic which means that the total concentration of all the dissolved solute particles is greater than the other solution. Core B was isotonic meaning

Question: How does mitosis produce new cells‚ and how is mitosis the same and different? Materials: - Compound microscope - Alliums root slide - Whitefish embryo slide - Power supply Procedure: Refer to page 48 and 49 in the textbook. Results: See attached sheet for drawings of my results. Discussion: Analyze and interpret question 1 and 2 on page 49. 1. The cells in the root tip region of the alliums differ quite a bit from the cells that are found deeper in the root

Mitosis in Plant and Animal Cells OBJECTIVES Observe and identify cells undergoing the process of mitosis. Compare the stages of mitosis in plant cells with these stages in animal cells. MATERIALS • compound light microscope • prepared slides (longitudinal sections of onion or garlic root tips) • prepared slides (whitefish blastula or other animal tissue) Procedure PART 1: MITOSIS IN PLANT CELLS 1. Observe a prepared slide of a longitudinal section of onion or garlic root tips. Use low

AP Bio p. 6 December 8‚ 2011 AP Biology Lab 5: Cellular Respiration Introduction/Lab Objective: In this lab we are testing how the process of cellular respiration is affected by temperature‚ and also how it is different between germinating and non-germinating peas. Cellular respiration is a catabolic process (breaks down organic material into usable cell energy) that produces ATP. The electron receivers are inorganic. Cellular respiration releases energy from organic material through chemical

Mitosis is the process in which a cell breaks apart its chromosome to eventually produce two identical daughter cells. The cell spends 10% of its time in mitosis. The cell goes through four stages in order to complete this task. The stages are Prophase‚ Metaphase‚ Anaphase and Telophase. Mitosis only occurs in eukaryotic cells and the process is different for different species. Mitosis is fast and very complex. The first phase is Prophase. In prophase‚ the chromosomes the chromosomes start to

The Lymphatic System Laszlo Vass‚ Ed.D. Version 42-0024-00-01 Purpose A. What was the purpose of doing this exercise? The purpose of this exercise was to learn about the lymphatic system and its components. We learned about lymph‚ structure and function of lymph nodes‚ T-Cells‚ B-Cells‚ and Macrophages‚ and differentiating between antigens and antibodies.

The Effects of Environmental Stimuli on Animal Behavior AP Biology Emily Olsen April 26‚ 2012 I. Introduction: The purpose of this lab is to test the effect certain stimuli has on the behavior of a terrestrial isopod. These bugs are more commonly known as pill bugs and potato bugs. The objective of this experiment is to determine which kinds of habitats potato bugs favor. Potato bugs have an innate behavior called taxis which will cause the animal to move away from a stimulus that is unwanted
