In the case of a floccular material growth there is moderate attachment‚ strength and growth but when poured onto a petri dish the biofilm breaks up into many small particles (Figure 2.). This is also a commonly found growth. A waxy aggreagate is the only biofilm from the four categories that is rarely found in experimental conditions. It is described as a strong biofilm

both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused at a faster rate of 24.8 cm and formed a white smoke near the HCl end that had the molecular weight of 36 g/mole. The water agar-gel setup was made up of a petri dish containing the gel with three wells. Drops of potassium permanganate (KMnO4)‚ potassium dichromate(K2Cr2O7) and methylene Blue were concurrently placed in the wells. Methylene Blue had the smallest diameter which diffused at the slowest Rate

MATERIAL AND METHODS 1. Materials: 1.1. Experimental animals: The experiment was carried out on 30 adult healthy female rats weighing 190 20g and 10 young (6-7) weeks –old male albino rats from which bone marrow mesenchymal stem cell (MSCs) were isolated. Animal were purchased from the animal house of the faculty of Medicine Mansoura University. The animals were housed in standard stainless steel cages at room temperature 25-28ﾟC‚ humidity of (50-60%) and maintained at 12 hrs alternating day

non-native seed germination. The experiment was set up by putting native wild flower seeds in six Petri dishes and lettuce seeds in six different dishes. To three of each dish containing the different seeds‚ water was added as a control. To the three other dishes‚ a prepared brittle bush tea (filtered ground brittle bush leaves and water) was added. After a week’s time‚ the number of germinated seeds in each dish was counted. The results showed that the allelopathic compound in brittle bush did have a significant

A total of four petri dishes were removed in the dark‚ using only a green safelight. They were then labeled with the variety of seed‚ group name or initials‚ the date‚ and the light treatment. Filter paper was added to each pert dish and then 2-3 dropperfuls of water were added to each plate so that the filter paper was very moist for germination. Then 25 lettuce seeds were placed into each dish. The light regimens were White‚ Red‚ Far-Red‚ and Darkness. Each dish was exposed to their labeled

Introduction: To achieve genetic experiments with haploid organisms‚ genetic strains of different genotypes must be crossed from one another. Following fertilization and meiosis‚ the meiotic products can be analyzed as the ascomycete fungus‚ Sordaria fimicola. Sordaria can be used as a model to study meiotic segregation. The trait followed was the ascospore color. Ascospore color is a single gene trait therefore it is easily observed under a light microspore. Which allele is dominant is very tough
