Answer:
Scientists figured out that the outer core must be liquid because S waves do not pass through it, but P waves do. The behavior of P and S waves also indicates that the inner core is solid. The speed of seismic waves also depends on the density of the material through which they are traveling.
Explanation:
The cellular structure that was visible in the transmission electron micro graph but not visible in the cells when microscope was used is NUCLEOLUS.
The transmission electron micro graph is a microscopy method that involves using electrons beams to form image of specimens. Transmission electron micro graph can be used to view minute structures of the cell because of its higher optical capacity.
The nucleolus was not seen under the microscope because is a very small cell structure.
Answer;
- Hydrogen peroxide
Explanation;
-Enzyme catalase is a protein enzyme present in most aerobic cells in animal tissues. Catalase is present in all body organs being especially concentrated in the liver & erythrocytes. The brain, heart, skeletal muscle contains only low amounts.
The substrate for the enzyme catalase is hydrogen peroxide. It catalyzes the decomposition of hydrogen peroxide to water and oxygen.
2H2O2 = 2H2O + O2
