Basics of Biology III
Enzymes and Animal Cells
What is the importance and function of enzymes? The lock-and-key principle is explained and, based on amylase and katalase, the dependence of reaction speed and intensity of effect on temperature and pH-value can be seen. With microscopic pictures and graphs the structure of animal cells is explained. But their appearance is very different depending on their functions. Nerve cells differ from blood cells just like the latter from sperm cells. A tissue is a combination of many cells that perform specific functions in the body. Any kind of growth of an organism is only possible when new cells are created. The process of cell division is called mitosis. This is then differentiated from the multiplication of reproductive cells, as in them the number of chromosomes must be reduced to half. Impressive shots and graphs illustrate these processes. Together with the extensive accompanying material the DVD is ideally suited for use in the classroom.

Air Traffic
Being able to fly has been a dream of humanity from time immemorial. But it does not even date back a century that people actually started being able to travel through the air. Since the 1960s, the number of flight passengers has been constantly increasing. Thus, the airspace is no longer dominated by birds but by man-made flying objects.
Tolerance
“Tolerance means being generous and kind to other people and helping them, too.”
Racism
Do you perhaps know that?
