Despite the increasing variety of household pets, not one pet can challenge the classic role of cats and dogs as the ultimate animal companion. A pet owner can identify as either a cat person or a dog person—an age-old question repeated to through time….

Using Sucrose Solutions to Determine Osmolarity of Potato Tubers Based on Weight By Thomas Pelikan Biology 200A Section 004 Kimberly Schmidt October 2, 2012 Abstract: In this experiment we were trying to determine the osmolarity of potato tubers by weighing them before and after incubating them in solutions of sucrose with varying molarities. To find…

Neural transmission is the process an electrical charge undergoes as it travels from the dendrites of a neuron to the terminal end of it’s axon. Once the electrical charge reaches the terminal end of the axon, neurotransmitters are released into the synapse, allowing them to bind with dendrites of the receiving neuron. The process starts…

Genomic DNA extraction from bacteria isolate was performed by who shows that Bacillus and Pseudomonas species have the maximum capacity to degrade oil but gave upper hand advantage to Bacillus species. Shows the presence of Alcaligens odorans, Bacillus subtilis, Corynebacterium propinquum and Pseudomonas aeruginosa in petrochemical refinery wastewater. The researcher positively collated high pollutant reduction…

Piaget’s theory of child development is an explanation of how a child constructs a mental model of the world in which they are born. Piaget does not agree with the idea of intelligence in children being a fixed trait. Rather, it results from biological maturation and interaction with the environment. The theory is aimed at…

Bacillus cereus is a Gram-positive, facultative aerobic, spore-forming, rod-shaped bacterium that is widely distributed among the environment. Introduction The reason for identification of unknown bacteria was to help students recognize different bacteria through different biochemical tests and characteristics. This is important in the medical field because identification of unknown bacteria can help treat a patient…

The gastrointestinal wall of an ovine intestine is comprised of four anatomically distinct layers intended for digestion, absorption, secretion and protection. The ovine intestinal epithelial cells (OIECs) are the first line of defense against pathogens and underneath, a thin layer of connective tissue- lamina propria rich in immune cells. Initiation of innate immune response is…

Introduction Deoxyribonucleic acid barcoding is a molecular tool for the designation of species of beings utilizing a comparatively short DNA sequence from a standard place in the genome. The cytochrome degree Celsius oxidase fractional monetary unit I ( COI ) mitochondrial part is fast going the standard barcode part. In most groups, the COI is…
