washed under running tap water. Then, they were surface sterilized with 0.1% mercuric chloride for a minute and rinsed three times with distilled water. They were further dried on filter paper and put on solidified Potato Dextrose Agar (PDA) in a Petri plate after cutting into small pieces (1 cm). The plates were then put under incubation for 6-8 days at 25±2°C. The mycelial growth of the fungus in the plates were observed for the association of M. phaseolina with the infected roots and was further

Abstract Plant-based antimicrobials represent a vast untapped source of medicines and further exploration of plant antimicrobials needs to occur. Antimicrobials of plant origin have enormous therapeutic potential. . Antimicrobials of plant origin have enormous therapeutic potential. They are effective un treatment of infectious disease while simultaneously mitigating many of the side effects that are often associated with synthetic antimicrobials. Present study was executed to mainly investigate

Bean Beatle Competition Lab RESULTS: In the two control petri dish that consisted of 20 beans with eggs previously on them, the females laid two to three eggs. In the two control petri dish that consisted of 20 beans without eggs previously on them, the females laid to 2 to 6 eggs. The average number of eggs laid on the eggs that already had eggs on them was 1.25 eggs and the standard error was 0.5522. The average number of eggs laid on the eggs that did not already have eggs on them was

experiment conducted, four sowbugs were placed in a Petri-dish with the options to choose between natural or artificial flavoring found in potatoes and grapes. A combination of instant potatoes and potatoes were used as well as grape jam and grape to figure out the preference of the sowbugs. The potatoes and grapes were thinly diced in order to accommodate similar shape and size to the artificial sample. Placed on opposite ends from each other in the Petri-dish, the sowbugs were then

the desired destination (Tunneling, 2011). The Opened Systems Interconnect (OSI) Model is a great example of tunneling. The OSI model is divided into seven layers and each layer provides a different task. The below chart is the OSI model (Petri, 2009). In the above chart data is transmitted and received. The user creates the data and now the user wants to send the data to another user or the desired destination. The data has to go through fourteen steps in order to reach its destination

Yeast Culture Lab I. Introduction 1. Yeasts are eukaryotic, unicellular fungi that inhabit liquid or moist habitats. They are heterotrophs and rely on complex organic substances for nutrition. Yeasts require oxygen for aerobic cellular respiration but some are also anaerobic with alternative aerobic methods for producing energy. They do not require light to grow and their temperature range varies which means they can survive in a multitude of different environments. Very common, they can be found
