Unit 1: fundamentals of science. Title An investigation of an onion cell using a light microscope. Aim: The aim of this investigation is to identify the cells within an onion skin using a light microscope. An onion cell is a plant cell which through the light microscope‚ it should outline the cell wall‚ cell membrane and the nucleus. Introduction: Plant cells have a cell wall and cell membrane which animal cells do not have. The cell wall provides support and is relatively rigid‚ which consists

This article from The Onion addresses the way that today’s scientific research is conducted and makes fun of how the source of funding for an experiment can influence its results. Interpreted plainly‚ the article claims that a new step has been added the scientific method: after a hypothesis is made‚ funding must be found. Then‚ based on who is funding the research and the sponsor’s desire‚ researchers must then align their study so it gets the results the funders want. The organization in charge

EXPERIMENT 13： Extraction: Extraction with acid and alkali Objective 1. To recover the benzoic acid and p-dichlorobenzene from its mixture from its mixture by using acid-alkali extraction. 2. To determine the percentage recovery and melting point of the recovered benzoic acid and p-dichlorobenzene. Introduction Acid-base extraction is a process which purifying the acids and bases from mixtures based on their chemical properties. Acid-base extraction is performed to isolate the compounds and natural

Commercialising from the bottom up: Onions in central Tanzania Draft Copy By Khamaldin Mutabazi‚ Ntengua Mdoe & Steve Wiggins Key points: • With minimal assistance and direction‚ small farmers in central Tanzania have created thriving plots of irrigated onions‚ marketed in Dar‚ other parts of Tanzania and in the region. • Lack of formal credit has not prevented many farmers fertilising their crops heavily. Two villages have been able to overcome poor road access. • Informal marketing work well

“Monologue for an onion” by Suji Kwock Kim The poem “Monologue for an onion” by Suji Kwock Kim begins with the peeling of an onion that could very well describe her and her agony‚ but further reading reveals that the majority of the poem is directed at the person doing the peeling. The reader cannot help but sympathize with the peeled onion‚ whether the emotions stem from the hurt state of the onion or from the aggressive peeler. Clearly the poet’s attack of the peeler grabs the attention of

ONION EPIDERMIS INTRODUCTION An eukaryote is an organism whose cells contain a nucleus and other structures (organelles) enclosed within membranes. Plant cells are eukaryotic cells that differ in several key aspects from the cells of other eukaryotic organisms. Their distinctive features include: A large central vacuole a water-filled volume enclosed by a membrane known as the tonoplast which maintains the cell’s turgor (provide structural support) and controls movement of molecules between the cytosol

Extraction of DNA from Calf or Hog Thymus/Isolation of Yeast RNA I. Abstract Nucleic acids may be divided into two groups RNA and DNA. DNA contains almost all the genetic information while RNA serves as the bridge between the DNA and proteins. Study of both DNA and RNA initially involves proper extraction/isolation. The storehouse of eukaryotic DNA is the nucleus (and in the mitochondria)‚ so experimentally‚ DNA is extracted from tissues that have a high nuclear to cytoplasmic mass ratio‚ such
