Answer:
The correct answer is a) It brings a transport liquid into close contact with all cells in the body.
Explanation:
The circulatory system helps in bringing the blood which is a transport liquid in close contact with the cells present in our body. This helps in gas exchange between cells and blood. The circulation of blood in the body occurs by the pumping of blood by the heart into arteries, veins, and capillaries.
This circulation of blood plays many other vital functions like transport of nutrients to the cells, transport of waste products from the cell to outside the body, transport of hormones, maintenance of body temperature, etc.
So all these processes become possible when transport liquid comes in contact with the cells. Therefore the right answer is a.
The answer is Prokaryotic cells
Answer:
Electric energy is all about seperation of opposite charges and bringing similar charges together. This is a potential energy which has to do with the Coulomb force.
Electromagnetic energy is energy in an electromagnetic wave, thus it is not associated with any particular charge it is in the oscillating fields themselves (Electric and Magnetic fields). The electromagnetic waves have a relatively simple expression for energy if the wave is harmonic, that is a particular frequency. Since harmonic waves are a complete set any wave can be decomposed to the harmonic frequencies that make it (Fourier transform).
