How do ionic compounds form? How do electrons change the shape of a molecule? These are just a couple of the questions that this paper will answer. How do ionic compounds form? Ionic compounds are formed by positive and negative ions. An ionic bond means that there are valence electrons being shared between the two molecules. This can cause the molecule to become negative or positively charged. An ionic compound is formed by the complete transfer of electrons from a metal to a nonmetal and the

The Ionic mechanism and propagation of action potentials. The action potential is the result of a large‚ sudden increase in sodium permeability of the membrane. The resulting rush of sodium ions into the membrane and accumulation of positive charge on its inner surface drives the potential towards Ena. This is followed by repolarisation‚ whereby there is a large increase in the membranes permeability to potassium ions‚ hence the membrane returns to Ek. Explanation of the (ionic) mechanisms underlying

Compare and contrast the use of light and electron microscopes in biological studies. Microscopes are laboratory equipment which are used to observe any matter that is too small to be seen by the naked eye. There are several types of microscopes – the two most common being the optical microscope‚ also known as a light microscope‚ and the electron microscope‚ which can be either a transmission electron microscope (TEM) or a scanning electron microscope (SEM). There are more differences than similarities

As stated in our reading‚ “Europeans were the original ones to introduce the Columbian exchange and the collision of humanities that took place in the New World. The results of contact were generally bad: the tale is mostly one of hunger‚ disease‚ and death.” [Work Cited. #1] Disease affected everyone‚ and unfortunately the results were not pretty. The Columbian Exchange was a crossover of agriculture‚ animals‚ and diseases that came from one society to the next. The more the Spanish people came

Biological influences are hard to measure because as a human you can change depending on your personal surroundings and the influential people in your life. I personally feel that you can be able to see ones biological influences as an infant because children at this age have been said to resemble their

one of the first theories of crime advanced‚ was the concept of biological positivism. Although this theory has gone in and out of favour over the course of history‚ it should be completely disregarded by criminologists as it is a deeply flawed theory which has little scientific research backing it‚ and has very little practical utility to reducing crime. Biological positivism was first proposed
