Breathing is one of the essential processes of the body that sustains life along with the cardiovascular and neural activities. More specifically, it is responsible for the intake and absorption of the oxygen, which, in turn, is supplied into the rest of the organs through blood. When it comes to the respiratory system of the…

Phototrophs Organisms are usually classified based on their nutritional need, and according to this criterion, there are two distinct groups, the phototrophs and the chemotrophs. Phototrophs rely on energy from the sun to manufacture their food in the form of ATP (Parker et al., 2017). The sunlight oxidizes organic molecules to produce energy, which is…

In mathematics, numbers can be represented in whole, integer, fractional, and decimal forms. Depending on the form, the mechanics of arithmetic operations to add, subtract, multiply, and divide them change. For example, regular recalculation adds and subtracts whole numbers, as shown in equations 1 and 2. Integer numbers are added and subtracted by considering the…

The olfactory system contains four major components that form the olfactory path. The first component, the olfactory receptor, also called the smell receptor, consists of millions of cluster receptor cells called the olfactory epithelium situated at the back of the nasal cavity. The olfactory sensory neurons provide a connection of information from the olfactory epithelium…

The Ring of Fire area is a dangerous territory that significantly impacts the tectonic activities of the whole Earth. From the scientific perspective, many plates have irregular positions and are at risk of collision. The plates subduction not only causes massive earthquakes but also provokes global climate change and dangerous tectonic shifts. Scientists are responsible…

Identifying population parameters is essential to the success of a research or the production process (Sharpe, DeVeaux, & Velleman, 2015). Herein the significance of the tools known as confidence intervals lies. Allowing estimating the key parameters of the target population, continence intervals serve as a means of reducing the chances for an error to occur…

A neuron is at rest when not sending signals. The resting membrane potential of a neuron is approximately -70millivolt. This indicates that the inside of the neuron is approximately 70millivolt less than the outside. When the neuron is at rest, there is more sodium outside the neuron and more ions of potassium inside the neuron.…

The sense of smell in humans, and in primates in general, is relatively poorly developed. Nevertheless, it’s role should not be underestimated. It is extremely important for a person, since one of the functions of the sense of smell is to prevent dangers that are invisible to other senses (sight or hearing). With the help…
