Archaebacteria = 10,000/20 = 500 species
Eubacteria = 10,000/1 = 10,000 species
Do the rest the same way, since you've got the graph right in front of you.
Answer:
EEG or electroencephalography
Explanation:
Electroencephalography or EEG is a technique to measure all the brain waves. These waves are occurred due to emotion, stress, or any change in stimuli received by the brain.
This is a technique where small metals are used to attach in the brain and detects the brain electrons wave. By using this technique individuals mental disorders like epilepsy and sleep disorders can be detected.
EEG measures the electrical activity of the brain. It also detects the activity of a large group of neurons.
Music therapy is also used with EEG to detect the anxiety, depression, of a person. As music induces strong emotions in a person, EEG is detected with music therapy.
But there are some limitations in this technique - it only detects the changes in the brain waves in the cortex, as the metals are attached to the skull. It can not measure deeper brain waves.
EEG also can't tell the exact location, where the brain wave changes. Because in a single time, it records several neuronal waves.
Besides these limitations, EEG is a useful technique to detect mental disorders.
Answer:
Rutherford coined the term protons and is positively charged particle present inside the nucleus of the atom. It has its own mass and is slightly less than the mass of the neutron.
Explanation:
It is believed that the protons are made up of 2 up quarks and 1 down quark. It helps to bind the nucleus together. It attracts negatively charged particle called as electron towards itself. Electrons are arranged in the orbit of the atom.
Answer:
during exercise there is an increase in physical activity and the muscle cells respire more than they do when the body is at rest
Explanation:
the heart rate increases during exercise as well as the rate of breathing, this makes sure that more oxygen is absorbed into the blood and more carbon dioxide is removed from it
