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
In this lesson, we learn about the 3 shunts of fetal circulation: ductus arteriosus, ductus venosus, and foramen ovale of the fetal heart: functions, medical significance, when they close, medical complications, and remnant ligaments.
You probably go to sleep most – if not all – nights. You probably have dreamt during many of these nights. And you might feel rested every time you go to sleep. Yet did you know about the complex mental processes that happen every time we go to sleep?
Have you ever had the experience of suddenly hating the food you once loved? Well, it turns out there is a term for it: conditioned taste aversion. Conditioned taste aversion is a type of classical conditioning in which a person develops a strong resistance toward one specific food after experiencing sickness, nausea, or any type of negative emotion.

Phosphorus Part 2: Health Risks and Disadvantages. Part 1 of this article described the uses and advantages of the element phosphorus. However, there are also various health risks that come with using phosphorus in our lives.
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.
A lesson plan look at the relationship between limits and the continuity of a function for calculus. In the last article, we started talking about limits and their applications for analyzing functions. In this article, we will look at how limits can be used to determine the continuity of a function at a point.

What is the respiratory system? In general, the respiratory system is a biological system that contains organs and structures that assist in gas exchange. Gas exchange involves the movement of carbon dioxide and oxygen between our circulating blood and air. In this educational lesson, we explore seven general functions of our respiratory system.
In this Harry Potter-themed physics lesson, we discuss about concave and convex lens and how to calculate and use the thin lens equation. Hop on board Hogwarts Express 9 3/4 for some magical mathematics and problem solving with physics lens!
