<span>An electroencephalogram (EEG) machine
EEG machine works by tracking and recording electrical activity of the brain in form of wave pattern. The instrument has electrode discs which are placed on ones scalp and then the electrical activity of the brain is detected and signals send to the computer which shows the result in form of a wave pattern. The doctors can there be able to detect any abnormal wave pattern and be able to diagnose if one is having seizure, stroke, tumor, epilepsy, brain death, coma or any other brain related abnormality.</span>
Answer: Option (a) is the correct answer.
Explanation:
Conduction is defined as the process in which there is transfer of heat through the material of substance due to the difference in temperature of adjoining regions.
For example, cooking omelet in a pan is a conduction process.
Thus, we can conclude that out of the given options conduction is the process which describes the transfer of heat through matter by molecular activity.
Viruses make us sick by killing cells or disrupting cell function. Our bodies often respond with fever (heat inactivates many viruses), the secretion of a chemical called interferon (which blocks viruses from reproducing), or by marshaling the immune system's antibodies and other cells to target the invader.
Without the proper balance of water, chemical reactions in cells could not take place
