researching‚ I predicted that I would see different numbers of cells (which are the bubbles or the circles in all the different stages). I got some pictures from a website and I knew what to do‚ and how to tell how many cells are in each stage after staining the onion root tip. Procedure I did this project all on my own. I had to wait one day to get the microscope‚ I then got the onion root tip and sliced it into small pieces. I stained the root with red food coloring to make it more visible‚ and

Granulocytes (polymorphonuclear leukocytes): leukocytes characterised by the presence of differently staining granules in their cytoplasm when viewed under light microscopy. These granules are membrane-bound enzymes that act primarily in the digestion of endocytosed particles. There are three types of granulocytes: neutrophils‚ basophils‚ and eosinophils‚ which are named according to their staining properties. • Agranulocytes (mononuclear leukocytes): leukocytes characterized by the apparent

In Ovid’s Metamorphoses‚ he often used the theme of forbidden or impossible love to bring forth a physical change in his characters. The love could have been blocked by a physical hindrance‚ patriarchal denial‚ or familial ties. When the character or characters try to kindle their love‚ a metamorphosis takes place. “Pyramus and Thisbe” is the tale of two lovers who have been neighbors since childhood. In lines 59 and 60 of book IV‚ Ovid writes‚ “notitiam primosque gradus vicinia fecit‚ tempore

Page 1 of 8 BIOLOGY 12- CELL STRUCTURE & FUNCTION Chapter Notes THE CELL THEORY • Although different living things may be as unlike as a violet and an octopus‚ they are all built in essentially the same way. The most basic similarity is that all living things are composed of one or more cells. This is known as the Cell Theory. • our knowledge of cells is built on work done with microscopes • English scientist Robert Hooke in 1665 first described cells from his observations of cork slices

When electrophoresis is done‚ proteins in a sample can be quantitated and analyzed. The separation of macromolecules in an electric field is called electrophoresis. A very common method for separating proteins by electrophoresis uses a discontinuous polyacrylamide gel as a support medium and sodium dodecyl sulfate (SDS) to denature the proteins. The method is called sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) where one can obtain information about the size of a protein or

The placard of law 451-A3H greeted Paul Sheldon as he sat down at his desk in the small‚ half-lit room. Like the derelict calendar on the wall beside it—somehow perpetually fixed on the image of a boy frozen in February—the cracked ceiling‚ and the gaping maw of the Royal type-writer in front of him‚ the sight of the law itself‚ was a hated but all too familiar feature of the surrounding space. Closing his eyes‚ he could‚ without any mental effort‚ trace the curled and fraying edges of its pages
