    Living, microscopic, unicellular organisms can be identified as microorganisms. Fungi, Protista, Bacteria, and Archaeans are four kingdoms in the phylogenetic tree of life that consist of microorganisms. Amongst these microorganisms the prokaryotes were the first ones to arrive through evolution. The rest of the life forms as we see them evolved from these simple creatures, prokaryotes. The smaller prokaryotes were swallowed by bigger prokaryotes setting the stage for the origin of eukaryotes. These eukaryotes then evolved into protists, fungi, plants, and animals. As they evolved, so did the way they reproduce. From simple asexual reproduction (binary fission) to sexual reproduction thereby expanding the diversity of the life…

    To Gram stain the given bacterial suspension and to differentiate between gram positive and gram negative organism. Visualization of microorganisms in the living state is very difficult, not just because they are minute, but because they are transparent and almost colorless when suspended in an aqueous medium. To study their properties and divide microorganisms into specific groups for diagnostic purposes, biological stains and staining procedures, in conjunction with light microscopy, have become major tools in microbiology. Chemically, a stain may be defined as an organic compound containing a benzene ring plus a chromophore and an auxochrome. Stains are of 2 types: 1. Acidic stains e.g., picric acid 2. Basic stains e.g., methylene blue. Types of staining techniques: 1. Simple staining. (Use of a single stain)This type of staining is used for visualization of morphological shape (cocci, bacilli, and spirilli) and arrangement (chains, clusters, pairs, and tetrads). 2. Differential staining. (Use of 2 contrasting stains)It is divided into two groups: (a) Separation into groups, Gram stain and acid-fast stain. (b) Visualization of structures, Flagella stain, capsule stain, spore stain, nuclear stain. The Gram Stain The Gram stain is the most widely used staining procedure in bacteriology. It is called a differential stain since it differentiates between Gram-positive and Gram-negative bacteria. Bacteria that stain purple with the Gram-staining procedure are termed Gram-positive; those that stain pink are said to be Gram-negative. The terms positive and negative have nothing to do with electrical charge, but simply designate 2 distinct morphological groups of bacteria. Grampositive and Gram-negative bacteria stain differently because of fundamental differences in the structure of their cell walls. The bacterial cell wall serves to give the organism its size and shape, as…

    The object of this experiment is to determine how changing the size of the beak of a finch will affect the population as well as the growth rate of the finch’s beak. The reason for the experiment is to evaluate evolution and how it affects the finch’s population, and how natural selection is always present in life. In this experiment I will show that the finch will continue to evolve until its beak has reached the optimal size for sustaining life, when changing the beak size to a much larger size we will see that the finch will have no need for further evolution of its beak and that its population will become much more stable and consistent throughout the years.…

    The control plates used in transformation are the LB and second LB/Amp plates marked with a “-“. The control for restriction digest was the ladder. The independent variables are the different cultures of the E. coli, and the +LB/Amp and +LB/Amp/ara plates form the experiment group. The dependent variable is whether the cells glow green under the UV light and whether they are resistant to ampicillin or not. The variables in restriction digest are the other 4 samples. The dependent variable is the length that the DNA fragments travel while the independent variable is the size of the DNA fragments.…
