The program ROQED Science: Update. Added new scenes.
- Newton’s third law.
Newton’s third law says that each of the bodies, acting on the other, receives a reaction
- Chemical reaction mechanism.
Chemical reactions are written in the form of equations, where the reactants and reaction products are indicated. However, most of the chemical reactions, as well as the preparation of the cake, take place in several stages.
- Saltatory Conduction.
Neurons transmit impulse at high speed.
Neurons are cells of the human nervous system; they carry a nerve impulse from a receptor to the central nervous system or vice versa. They can reach one and a half meters in length, while maintaining the speed of impulse transmission, reaching a speed of 120 m / s. Reaction speed is very important for human survival.

- Mitosis. Biological significance.
Mitosis is the process of cell division that is essential for the growth and development of the body. What is the biological meaning of mitosis? It produces genetically identical daughter cells with the same diploid set of chromosomes as in the mother cell. The constancy of the chromosome set is maintained.
