Category “Chemistry”: 

  • Strong and weak acids and bases.
    Acids are substances that consist of hydrogen and an acidic residue A. Acids break down into ions in aqueous solutions. There are strong and weak acids. 
  • Chemical reaction rate. 
    Consider the reaction of a vitamin C tablet in water. When we put the tablet in water, there is a reaction between the components of the tablet with the release of carbon dioxide. The solution is painted in a bright yellow color. 
  • Chemical properties of oxides. 
    Oxides are compounds consisting of two elements, one of which is oxygen. Oxides are divided into basic ones, such as sodium oxide, acidic ones, such as phosphorus oxide, and amphoteric ones, such as beryllium oxide. 

Category “Anatomy”:

  • Endocrine glands and their hormones. 
    The endocrine system is a system of glands that release chemical molecules, namely hormones, into the bloodstream. Hormones act more slowly than the electrical signals of the nervous system. Hormones move within the bloodstream and affect the entire body.
  • The neuromuscular junction. 
    A neuromuscular junction is a chemical synapse between a motor neuron and a muscle fiber. It allows the motor neuron to transmit a signal to the muscle fiber, causing the muscles to contract. 

Category ” Physics”: 

  • Molecules of substances in different states of matter (solid, liquid, gas). 
    We know the formulas of angular and linear velocity. By comparing them, we can see the similarities between them and combine the two formulas. It turns out that objects with the same angular velocity can move at different linear speeds due to the difference in radius.

Category “Cell Biology”: 

  • Globular and fibrillar protein. 
    Two classes of tertiary protein structure 
    Proteins of the tertiary structure can be divided into two classes — globular and fibrillar proteins. The fibrillar proteins are long and thin, while the globular proteins are spherical.
