Sure, curiosity killed the cat, but it did the exact opposite for the world of science. Curiosity has been the bedrock of the various sciences for hundreds of years. Without it we might never have understood light, gravity, engineering, and in particular chemistry. Chemistry is a physical science that studies the make up, design, and properties of matter. It also looks to discover changes in matter itself, on an atomic level. Without curiosity scientists might never have looked as deeply as they have into the atomic recipes that make the world … well, the world. Without the curious chemists we would not even understand what an ion is, let alone a common one! If you have a love of science and want to learn more about chemistry and ions then you should take Udemy’s chemistry course. Start with Part One: Principles of Chemistry and get your curiosity up and running.
Biology is a broad field of study concerned with the natural sciences, including the life, classification, function, and evolution of living organisms. Within the actual field, there are several different degrees you can obtain, and a diverse range of jobs you can land with any one of them. In this guide, we’ll cover several careers in biology that someone with a degree in a related science can consider, and how they differ according to the distinct field of biology to which they belong.
If you don’t have a degree in biology yet, and are just contemplating your career options before you pursue one, this is also a great way to see where specific types of biology degrees can land you. For some entry-level study material to gauge your interest or supplement your studies, check out this introduction to basic biology course.
Messenger RNA or mRNA is also called messenger ribonucleic acid. This is a type of ribonucleic acid or RNA transcribed from a DNA (deoxyribonucleic acid ) template. One strand of mRNA consists of four different base types including uracil, cytosine, guanine and adenine. Ever one of these bases corresponds to an antisense DNA strand’s complementary base. Also, an organism’s genetic information is encoded into the mRNA, which you can learn more about in this Biology course.
The enzymes in living organisms are very large molecules that are essentially responsible for sustaining human life. Enzymes perform thousands of metabolic processes that keep a living organism alive, but there is no guaranteed explanation for how it works. What makes enzymes even more interesting is the fact that they are highly selective. An enzyme isn’t activated by just any substrate. In fact, enzymes only catalyze certain reactions and it chooses specific substrates involved in the reactions.
Enzymes are complicated molecules, but they only make up one component of the various things that go on in living organisms on a molecular level. If you’re interested in learning more about molecular organisms and how they help sustain life, then you should check out the Udemy course, An Introduction to Basic Biology.
Hydrophilic amino acids are organic molecules that form proteins when linked together with other amino acids. Amino acids are classified as hydrophilic when they seek contact with aqueous solutions. Hydrophilic amino acids are the opposite of hydrophobic amino acids, which avoid contact with liquids and which you can learn more about in this Biology course.
Of the twenty amino acids, here are the ones which are hydrophilic: [Read more…]
Copper is an amazing chemical element that’s been used within society since the ancient days of the Romans. Its reddish-brown color makes it easily recognizable, but this metal is used for far more than just the US penny. Thanks to its versatile chemical properties, copper is used for a wide variety of purposes within our daily lives, most of which go unnoticed. So if you’re interested in copper and similar chemical elements, then feed your curiosity by taking a class on the basics of chemistry from Udemy. It will help you learn about the essential chemicals we use everyday and their unique chemical properties, such as copper.
When you’re doing chemistry, the balances that are given are read in grams. Unfortunately, the standard unit of measurement is in moles, not grams. Calculating moles or the molarity of a solution involves measuring how many moles of a solute exist per liter of that solution. Fortunately, the process of solving molarity problems is pretty simple, and with a bit of practice, you will undoubtedly be able to do mole calculations with ease. The biggest pitfall you have to avoid is conversions. Conversions can easily make a problem much more difficult.
Calculating moles is something that you will do as a beginner in chemistry, and as you take more advanced classes mole calculations will become increasingly difficult. If you really want to learn how to calculate moles properly, then you should check out the Udemy course, Chemistry 101 – Part 1 Principles of Chemistry. There’s also the Chemistry 101 – Part 2 course, which you can check out if you’re ready to move on to more advanced studies in the subject.
Elements play a key role in chemistry because they are the simplest form of matter available in chemistry. Basically, they can’t be chemically broken down into something simpler, like the atoms they’re made of. The atoms that make up elements are made up of three key pieces – electrons, neutrons, and protons. Each element is known by an atomic number. This atomic number defines the number of protons held in the nuclei of the atoms.
Many elements will be made up of atoms that contain valence electrons. This means that they can react with atoms from the same element or atoms from other elements to create compounds. You can learn more about valence electrons with this useful article. You can learn more about elements with an online class, but you can also read up on some basic information about elements below before starting your class.
Since our planet’s beginning, there have been rounds of animal extinction. The most popular of this is what happened to the dinosaurs millions of years ago. Our planet was filled with exotic, giant creatures who ruled the land for years. But no matter how powerful they were, it didn’t protect them against extinction. Since then, there have been many animal species that have become endangered and ultimately, become extinct. Many animals’ extinctions are a result of human doing. It is a sad truth, but we can do something about it as well. In this post, we will take a look at the top 10 endangered animals and discuss how we can help protect them and keep them from extinction.
There are many things humans are currently doing to put animals’ lives in risk. There are also many things humans can do to help protect these endangered animals as well. One of the biggest troubles we face in this world is the amount of pollution we put into our air and environments. It is important to know the things you are doing in your everyday life that affect our planet and the things you can do to lessen the impact you have on the Earth. You can take a deeper look into our individual effects on the planet with this course. In it, you will learn the human influence on our environment and what you can do to help improve our environment.
