Neurons are electrically excitable cells in the human bodies that communicate with other cells through specialized connection referred to as Synapses. Each neuron has a cell body with many minute branched short protoplasmic extensions referred to as dendrites and an elongated unbranched protoplasmic extension referred to as Axon. What Are Myelinated Nerve Fibers? Myelinated Nerve … Read more

Intensive Distribution, Exclusive Distribution, and Selective Distribution are three different distribution strategies that companies use to make their products available to customers. The chosen level of distribution chosen generally depends on different factors such as the production capacity, the size of the target market, pricing and promotion policies as well as the seasonal requirement of … Read more
Neanderthal Neanderthals, or Homo neanderthalensis, were a species of hominins that lived in Eurasia from approximately 400,000 to 40,000 years ago. They are one of the closest extinct relatives of modern humans (Homo sapiens) and have fascinated scientists and the public alike for many years. The first fossil described as Neanderthal was first discovered in … Read more
Forging Forging is the metalworking process involving the shaping of metal using localized compressive forces. At the end of the forging process, the resulting product features extreme strength, impact toughness and wear resistance due to thermal and mechanical treatment. Forging can be classified according to the temperature at which it performed: cold forging, warm forging … Read more
Co–dominance is a form of dominance whereby the alleles of a gene that pair in heterozygote are fully expressed. This results in offspring with a phenotype that is neither dominant nor recessive. A good example showing co-dominance is the ABO blood group system. On the other hand, Incomplete dominance also referred to as partial dominance … Read more
Description Chromatin is a complex of nucleic acids (DNA and RNA) and protein found in the eukaryotic cell nucleus whose primary function is packaging very long DNA molecules into a more compact, denser shape, which prevents the strands from becoming tangled. It also plays an important role in reinforcing the DNA during cell division, preventing … Read more
