When it comes to research in any field, there are several factors to be considered when it comes to how seriously it is to be taken, for example, the methodology used and its reliability. If research is conducted through a faulty methodology, its results should automatically be taken with a grain of salt. The reliability …
The three domains system is a classification used in biology that divides cellular life forms into three categories: archaea, bacteria, and eukaryote domains. It was introduced in 1977 by Carl Woese et al. One of its characteristics is that it points out the separation into two groups of the prokaryotes; Eubacteria (now called bacteria) and …
A collection of individual organisms of the same species that live in a specific area is what is known as a population. But when we want to talk about how the number of individuals of a population changes over time, then we would use the term “population dynamics”. The reason why scientists and biologists pay …
The Bottleneck Effect or genetic bottlenecks happen when there’s an event that drastically reduces the number of individuals in a population. This can occur due to environmental events, for example, famines, disease, droughts, earthquakes, fires, etc., or human activities, such as genocide or wars. These types of events can reduce the gene pool of a …
One very useful feature of a smartphone is that it “knows” in which direction it’s pointing, so when you use a compass app, it knows if you’re going north, south, east or west. Many technologies today, that include smartphones, are able to identify their orientation thanks to a device known as an accelerator, which is …
An inert gas, is a gas that under certain given conditions doesn’t have chemical reactions. Noble gases don’t react very often with many substances, and were referred to as inert gases for a long time.Inert gases are commonly used when degrading a sample and chemical reactions are to be avoided; such chemical reactions include oxidation …
An alveolar macrophage, also known as a dust cell, is a type of cell that is located in the pulmonary alveolus close to the pneumocytes, however it is separated from the wall. Their location is crucial because it is one of the main boundaries that separate the body from the outside, so the activity of …
Let’s get one thing straight: proteins are one of the most important substances in the human body. Your hair, eyes, muscles, organs, many hormones and enzymes are mostly made up of proteins. When your body tissues need to be repaired or maintenance, proteins are highly involved. But, not all proteins are the same, nor are …
A codon is a sort of genetic code that has a set of rules, where specific information is encoded in the genetic material that can either be DNA or mRNA sequences, which is then translated into proteins. The proteins that are synthesized are made up of amino acids that are placed together in a specific …
Bones are one of the hardest human body parts and they can be very difficult to break, however, they are not absolutely immune to damage. If enough force is applied to them, the can indeed break into pieces. A comminuted fracture is a type of injury where the bone breaks into more than two pieces. …
