Mycobacterium Smegmatis & Bacillus Subtilis Endospore Stain: Abstract Endospore and acid-fast staining are differential staining procedures used to identify bacteria with unique cell properties. The purpose of this lab was to use endospore and acid-fast staining to distinguish between two bacterial species. Old liquid cultures of Bacillus subtilis and Mycobacterium...
Introduction The first question this research attempted to explore was how different water treatments affect maximum plant height. The hypothesis stated that the greywater would result in shorter plants in the experiment because such water has potentially harmful chemicals and materials that may have adverse impacts on the soil in...
What was Pangaea? According to the continental drift theory, over 300 million years ago, all the continents were joined together forming a single landmass surrounded by water. This landmass is called Pangaea. List 4 type of evidence which supported continental drift The continental drift theory supposes that over 300 million...
Mitosis Mitosis is the process of cell division; as a result of it, two identical cells emerge. The cells of all types, except for sex cells, multiply via mitosis. Mitosis occurs in several phases (Dawson, 2002; The University of Arizona Biology Project, 2004): Meiosis Meiosis is the division of cells...
This paper is aimed at discussing the similarities and differences between cats and dogs. These animals are often regarded as bitter antagonists that cannot co-exist. Nevertheless, they can actually bear resemblance to one another. For instance, one should mention their interactions with people and their eating habits. Nevertheless, it is...
According to Robert M. Sapolsky, human beings feel that they are unique, unlike other species. This has been questioned by studies that have been done on other primates. Theodosius Dobzhansky, an evolutionary biologist, viewed that all species are unique. According to him, humans are unique; thus, they feel more proud...

Metal chelate affinity chromatography is a method based on the different affinity of organic compounds to ions of some metals. The concept of metal chelate affinity chromatography (MCAC) was first formulated and presented by Porath in 1975. It was based on the well-known affinity of transition metal ions, such as...
Abstract Wisconsin fast plant is one of the most unpretentious plants that can be utilized to carry out detailed experiments regarding seed growth trends. The current research project investigated the problem, with the primary research hypothesis being that the number of seeds is directly related to the speed and quality...
Introduction Chemical experiments can teach students a lot and show new unknown properties of certain substances. However, in order to protect self and others, it is crucial to adhere to specific rules. They will help perform laboratory tasks safely and without harm to the body. There are special norms and...
Introduction Nitrogen (N2) is the most abundant though crucial to living things element that can be found in the water, air, and soil. To a great extent, the nitrogen cycle is a systematic biochemical process under which nitrogen is converted into several usable forms, including nitrates and nitrites. Such nitrogen...
Introduction Ever since biochemical evolutionary processes caused the origin of life on Earth several billion years ago, the drivers of natural selection, heredity, and variability have resulted in a wide range of biodiversity. This diversity is the foundation for questions about what determines the properties of living matter in the...
