gram-negative bacteria which do not stain purple and into gram-positive cells which does stain purple. Bacteria that decolorize easily are called gram-negative‚ and those that decolorize slowly and retain a primary stain are called gram-positive. The gram staining procedure consists of fixing a colony of bacteria onto a slide and then flooding the colony with various chemicals. First‚ crystal violet dye was dropped onto the bacterial cells‚ staining gram-positive cells purple. Iodine was added to fix the violet

many “thinkers” or “dreamers” thought that children’s development happens in different stages and that with each of the stages; it shows a different challenge for each individual child. When it comes to children’s literature‚ like “Harold and the Purple Crayon”‚ if successfully used‚ the literature can be used for parents to use to help the children to classify with the developmental stage that they are in and sometimes even get the child prepared for the stage that they could be going into next

included almost all the information that is required such as: facilities‚ event and time and place. It also includes information regarding the hiring of a stalls or volunteering. The colours are appropriate as they match my logo colours which are purple‚ blue and orange. It also doesn’t look sloppy or unprofessional but rather fun and exciting. My test buddy liked my colour combinations and the animations on each slide; they also wanted me to loop my movie. The only change I made was that I looped

Properties of Water Lab # 1 Biology 111 January 23‚ 2011 INTRODUCTION With surface tension it is made possible for items such as paper clips to float on water‚ because a molecule within the mass of a liquid encounters gravity to all adjacent molecules in all directions. When you use surfactant substances this creates hydrogen bonds. Purpose of experiment 1 will be to show that once the surfactant substances hits the hydrogen bond pulls down paper clips. Things

Through the selective cross-breeding of common pea plants (Pisum sativum) over many generations‚ Mendel discovered that certain traits show up in offspring without any blending of parent characteristics. Each variety has a different color flower‚ one purple and one white. This flower color varies among each individual and is called character. The reproductive organs of a pea plant are in its flowers‚ and each pea flower has both pollen-producing organs (stamens) and an egg-bearing organ (carpel). Although
