Many students, as well as adults, may be wondering what buffers do in biology. Buffers are actually the combination of weak acids and their salts of strong bases. Buffers can also be a mixture of weak bases and their salts of strong acids. Buffers assist in maintaining a normal pH level in biological systems. This […]
If you teach high school biology, then you’re already aware of how fun and exciting this topic can be. However, teenagers aren’t typically interested in science, and creating some custom biology experiments for high school can be a great way to make learning biology more exciting. You can also enhance the interest of your students by […]
Virtually everything in our environment involves some sort of science. For example, this simple task of cooking a chicken dinner involves not only biology but chemistry as well. This is the reason that is so important for younger students as well as older ones to understand the importance of science experiments when it comes to […]
Adenine, C5H5N5, is a purine, a ring-shaped organic compound. Just about every biology student will be familiar with adenine as the “A” in “A-G-C-T,” the four bases of DNA. Adenine, of course, also appears in RNA. Adenine bonds by hydrogen bonds with thymine to stabilize DNA, and it forms hydrogen bonds with uracil to stabilize […]
The concept of cellular respiration can be a little intimidating to introductory biology students, until they realize that it is really just about the biological processes that can take things that we find in food and convert them into energy. Beginning biology students will have an intuitive understanding of “energy.” They get the idea when […]
Pigments in plants capture the energy of light for the synthesis of carbohydrates. Pigments such as chlorophyll enable plants to harness the energy of the sun. What is special about the light that activates pigments? Light is energy that travels in waves, like other forms of electromagnetic energy such as x-rays, radio waves, and microwaves. […]
Gel electrophoresis experiments bring important concepts of molecular biology to life for students. They give students laboratory skills they can use for the rest of their careers. And because the results of gel electrophoresis are visual, they are just plain fun. Modern Biology provides everything biology instructors need for specific experiments, assuming their labs are […]
Laboratory experiences give biology students opportunities to develop a scientific approach to answering life’s most interesting questions. Time spent in structured investigation in the laboratory reinforces concepts learned in the classroom. Modern Biology provides the specialized equipment and reagents students need to conduct laboratory investigations, but every lab needs these 20 basics. Students in labs […]
What Is A Peptide Bond Simple Definition? A very basic explanation could run something like this: We tend to think of protein as a macronutrient, a kind of homogeneous substance that everyone needs in their diets. But as you have been learning in your modern biology labs, protein isn’t a single substance. There are lots […]
Anyone who has passed Chemistry 101 understands the definition of molecular weight: The molecular weight of any elemental substance, or any compound, equals the sum of the atomic mass units of all the individual atoms in its chemical formula. Look up the formula, look up the atomic mass of the atoms that make up the compound, […]
