Problem 1. Before you chart of the basic natural sciences:
Specify interdisciplinary science, letters marked on the chart
A B C D:
Task 2. On the basis of the principle of causality, recognized methodology of natural science, make a causal chain of the following events:
1) the occurrence of an electrical discharge in the atmosphere
2) the accumulation of electrical charge on the clouds
3) a flash of lightning and thunder
Problem 3. Place in a sequence that reflects the order in which they perform the steps of the experimental method of Galileo:
Task 4. Completion experimental proof of the existence of electromagnetic waves Popov was a demonstration in 1896, the first transmission of telegrams at a distance of 250 m, lies in two words "Heinrich Hertz" sent at the speed of propagation of electromagnetic waves Vc = 3108 m / s.
After some time, the signal sent t reached the receiver?
Problem 5. Specify the basic formulas of relativistic mechanics.
6. The task of elementary particles that transmit interactions are gravitons, photons, weak bosons, gluons. Put these concepts in conformity with the types of fundamental interactions in nature, transmitted by these particles.
Problem 7. Make the correct conclusion from the above text.
According to the theory of the chemical structure, the carbon atoms can be joined together in various ways and with atoms of other elements to form a great variety of organic compounds, for example:
Problem 8. Place in order of their degree of complexity, these levels of organization of wildlife:
Task 9. As a result, crossing two-clear two-hybrid varieties of peas with yellow and green seeds smooth wrinkled received four distinguished by their appearance, the group of second-generation hybrid seeds - yellow, smooth, wrinkled yellow, green, smooth, green wrinkled. Given that the yellow color and smooth is the dominant form of seeds, and using a combination of features of independent law Mendel, calculate how much was shown a yellow smooth seeds, if you know that in the other groups the number of seeds were distributed as follows: yellow wrinkled - 900, green smooth - 900 green wrinkled - 300.
Problem 10. Put the following biogeochemical functions of living matter in accordance with their definitions set forth in the teachings of Vernadsky's biosphere.
