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…

Mitosis and meiosis are both important to a living organism because they represent cell divisions that are very important to every living organism because without cell division all living organisms would fail to reproduce, eventually dying out. Cell division plays a very important role in the life cycle of a cell. Mitosis and meiosis are…

Homeotic complex (Hox) genes are defined as a group of related genes that specify the anterior-posterior axis and segment identity of metazoan organisms during early embryonic development. These are situated very close to one another on the chromosome in groups of clusters. The orders of these genes located on the chromosomes are the same as…

Differential Staining Questions: A.What is a differential stain? How is it different from a simple stain? 1.A differential stain is a stain that differentiates between gram-positive and gram-negative bacteria. Bacteria that stain purple are considered gram-positive and those that stain pink are considered gram-negative. 2.A simple stain is a stain that reacts with all microbes…

Neurotransmitters.             Neurotransmitters refer to certain chemicals agents which relay, modify and modulate signals from the neurons to other cells in the body (Rang, 2003).  When these chemicals are secreted at terminal axon ends of the nerve cells, they diffuse across the synaptic gap thereby transmitting information to the nearby adjoining cells such as glands,…

This experiment examines cell membrane permeableness, osmosis and membrane electromotive forces ; all of which are of import in understanding how cells are affected by their environment. The motion of H2O across membranes is of import for cell volume and therefore the volume of extracellular compartments. The mechanisms for solute conveyance are indispensable in keeping…

By GERARD CHRETIEN BIOLOGYCellular PathwaysSeveral principles govern metabolic pathways in the cell:A. Complex chemical transformations in the cell do not occur in a single reaction, but in a number of small steps that are connected in a pathway. B. Each reaction is catalyzed by a specific enzyme. C. Metabolic pathways is catalyzed by a specific…

Discuss the different ways in which metabolic procedures are regulated and the possible effects for an being if this ordinance malfunctions. Metabolism is many co-ordinated chemical reactions happening within a cell of an being to prolong life ( Berg et al. 2006 ) . Obtaining foods, bring forthing wastes, turning, reproducing, accommodating to different environments…

Over view of the digestive system Two groups of organs compose the digestive system: -The gastrointestinal tract and the acessory igestive organbs the gi tract is a continous tube that extends form the mouth to the anus, the gi tract contains food from the mouth to the anus the gi tract contains food from the…
