ABSTRACT The purpose of the study was to detect the rates of hyphal tip growth and nuclei position of N. crassa in influence of drug medium, Taxol. The results of the experiments show that the rate of hyphal tip growth and nuclei position are much lower in drug medium than in the control. Taxol have different effect on growth of tip and distance travelled by nuclei. Moreover, the rate at which the nuclei displace and growth of the tips are dependent on the medium and not on each other. Thus, the

Using ATP To Contract Glycerinated Muscle Introduction Muscles are a fibrous bundle of tissues that contract to produce movement in the body. There are three different types of muscles, cardiac, skeletal, and smooth. Though these three different types of muscles serve slightly different purposes, they function very similarly. The main components of muscles are muscle fibers, myosin, actin, and a few more. Muscle contractions works primary off of the interaction between the proteins, actin and myosin

What is the function of enzymes in a living system? Enzymes speed up metabolic reactions necessary for life. Without them certain vital processes would not take place and the body would be unable to function. Difference enzymes work better under different conditions. Where in a human body might it be beneficial to have enzymes work in very acidic environments? In areas, like the stomach, that have a pH of two would benefit by having enzymes that function well in acidic environments. An example

animals. Mealworm beetles are part of the Kingdom Animalia, Phylum Arthropoda, Class Insecta, Order Coleoptera, Family Tenebrionidae, Genus Tenebrio, and Species Molitor. During the experiment, 10 mealworms were placed in one side of a two chamber petri dish. The opposite side was covered in a shade cloth to create darkness on one of the two chambers. The mealworms were exposed to the different types of the light in the starting chamber, and mealworms remaining in the starting chamber were counted

Aaron Mennitt Sec. 020 2/12/14 Introduction Beauveria bassiana is a member of the Fungi Kingdom. It acts as a parasite on insects and causes White Muscardine disease. It is being used as an insecticide to control certain arthropod species [Boyd]. The article, “Does Elevated Body Ni Concentration Protect Insects Against Pathogens?” uses Beauveria bassiana as one of its main test tools in its experiment. The author of the article wanted to test to see if higher Nickel concentrations in an insect

2015-2016 ABSTRACT The relationship of molecular weight and rate of diffusion was determined using three colored substances with different molecular weights, namely Potassium permanganate, Potassium dichromate and Methylene Blue. A water-agar gel in a petri dish was used to be able to observe the movement of the particles of each substance. Potassium dichromate had the fastest rate of diffusion among the three substances. Thus, the smaller the molecular weight, the faster the rate of diffusion. INTRODUCTION

3 Basic plate count techniques for the enumeration of microorganisms 3.1 Introduction Most of the recommendations and guidelines contained in this chapter are taken from American Public Health Association (APHA), as described in the Chapter 6 of the 4th Edition of the Compendium of Methods for the Microbiological Examination of Foods (Swanson et al., 2001). When different from or complementary to those of the Compendium, they were complemented with information and recommendations from

slants of nutrient agar and 2 slants of nutrient broth. 1 agar Petri dish. # 11 We inoculated nutrient agar using the needle by one streak from bottom to top. Broth was inoculated as well. One slant and one broth incubated at 25 C and other slant and broth at 37 C. Purpose 1… To determine optimum temp for bacteria Purpose 2… To start collecting morphological characteristics of colonial growth of the bacteria. Color of bacteria in Petri dish is yellowish beige. There are numerous small colonies.

available for MS Windows, Solaris, Linux and some other operating systems. MySQL is widely used among individual students and larger Organizations due to the following reasons. MYSQL is almost free of cost; it is much less expensive than Oracle (Petri, 2005). Each and every individual student can set up MySQL locally on their own computer system. It is really simple to use Shell in order to query tables, create tables etc. MySQL is simple to use with Java JDBC (Java Database Connectivity)
