Explanation:
multicellular means it's forms tissue
Answer:
The correct answer is C. Hypothalamus
maybe it's called osmosis?
This energy most directly results from the life activity of respiration.
The hummingbirds have very high energy expenditure (have the highest oxygen requirements of all vertebrae) with a fast heart rate, very fast wing beats and sustained hovering. So the hummingbird is nearly always on the edge of starvation, needing to take in more nectar than its body weight each day.
The respiratory system of these birds is highly adapted for the high oxygen needs. So, the muscles of the hummingbird cause pressure changes within the air sacs. As a result, more oxygen can enter the respiratory system. Also, they have the highest density of red blood cells which allows them to rise heart beat to around 500 breaths per minute during flight.
<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>
