Innate vs Adaptive Immunity: What are the differences between innate and adaptive immunity? The human body has two protective immunological systems against pathogens: the innate immunity and the adaptive immunity. In this quick and easy lesson, we will explain the differences between the innate and adaptive immunity. The innate immunity and adaptive immunity differ based on the type of components that are used to protect the human body. For example, the innate immunity consists of neutrophils, dendritic cells, natural killer cells, macrophages, complements, physical barriers. On the other hand, the adaptive immunity contains components such as T cells, B cells, and antibodies to protect us from viruses, bacteria, and other pathogens.
The heart’s function is to consistently move the blood in the body for the blood to spread nutrients to other body parts or to be replenished with oxygen and nutrients from other respective organs. The heartbeat is a way to understand the pace at which the blood is moving and how quick the heart is pumping itself. A heartbeat changes based on its environment. Running and high-intensity movement causes the heart to increase its number of beats whereas resting may lead to a lower heartbeat for the low amount activity that does not require as much oxygen. Depending on the difficulty and intensity of each activity, the heart accommodates via changing its pace to fit the body’s needs. In certain cases, however, a cardiac arrhythmia occurs and can lead to different cardiac issues that may or may not be harmless. Cardiac arrhythmia has affected millions of people in a multitude of forms. This article explains the basics of this condition such as heart block and bradycardia. The article is solely for educational purposes and not to diagnosis. What is a Cardiac Arrhythmia?
Cougar. Mountain Lion. Puma. What do these animals all have in common? Believe it or not, they are actually all names for the same animal! Because this feline spans such a large area, different areas call it different names. As you might think, this could get confusing if scientists try to discuss the same animal, so what do they do? They use taxonomy.
Taxonomy is the science and process of organizing organisms into categories and naming them. Every species of animal has a unique taxonomic, or scientific, name. A species is a group of organisms that reproduce among itself and produce offspring. The scientific name is used by scientists all over the world for ease of communication. After all, it is very important to be specific in science. For example, the scientific name of the cougar/mountain lion/puma is Puma concolor. The name cougar/mountain lion/puma refers to the animal’s common name. Organisms can have many common names used by the public, but when scientists are referring to them, they use the scientific name. Domain Kingdom Phylum Class Order Family Genus Species
Climate change affects the entirety of the earth’s surface, and nowhere more so than our oceans. While our seas cover about two-thirds of the earth’s surface they absorb over ninety percent of the additional heat attributable to global warming. Both land masses and bodies of water absorb and reflect solar radiation that rebounds off of the greenhouse gases trapped in our atmosphere, but the latter is generally more absorptive and holds on to heat longer due to differences in physical properties. This of course has led to increases in global seawater temperatures, which has and continues to endanger several aquatic species. This article will examine one of those species and go over human efforts to preserve it.

For the average person, washing their hair every day or every few days is a matter of hygienic preference rather than necessity.

So, what is the true science behind our “dirty” hair and the ingredients in our shampoo?

One way of looking at history is in terms of progress. Many historians and fans of the subject laud Rome for its advances in military organization, infrastructure, and civics. Similar adulation is often heaped upon the Renaissance for the strides made in philosophy, arts, and sciences during that period, which in turn set the stage for the Age of Enlightenment. But what of the time between shining antiquity and the rekindling that was the Renaissance? lternately called the Dark Ages, the Middle Ages, and the Medieval Ages, the time period from roughly the 5th century to the 15th century is usually framed in the West as its own era of history.

The basics of rewilding (at least in North America) are the Three C’s: Cores, Corridors, and Carnivores. Rewilding was developed in the 1990’s as a new approach to ecological restoration. Proponents have characterized it as being active rather than reactive. What this means is that instead of viewing conservation as stemming a tide or becoming shepherds to ever-declining animal populations, rewilding is focused on restoring the equilibrium of ecological systems. This is accomplished through a variety of methods that are grouped together under the Three C’s.

Vitamins and minerals both help our bodies work properly, and they aid with functions such as growth and development. So what is the difference between the two? Simply stated, vitamins are organic and minerals are inorganic. This means that vitamins come from living sources, like plants and animals, while minerals come from elsewhere, such as the earth. Vitamins tend to have more complex structures than minerals, and because of this, are more prone to degradation via heat or chemicals. Today, we will be focusing on vitamins.
The muscular system allows us to move and do our daily tasks. It also provides heat, stability, and blood flow for our body. There are three main types of muscular tissue: cardiac muscle, which comprises the heart muscle, smooth muscle, which comprises the linings of organs, and skeletal muscle, which are the muscles that help our body move. This article will focus on the physiology of skeletal muscles.
