Answer: All birds are warmblooded, or endothermic, animals. Birds are vertebrates because
they have backbones. All birds have a four-chambered heart, a
characteristic they share with mammals. All birds lay hardshelled eggs. Birds have only two legs. Their forelimbs have
become modified into wings for flying. All modern birds evolved
from ancestors that could fly.

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:
A solution at pH 6 contains<u><em> 100 times more H+</em></u> than the same amount of solution at pH 8.
Explanation:
pH of a substance determines the hydrogen ion concentration of a solution. Acidic solution tend to have a higher concentration of H+ ions as compared to that of water. They have a concentration greater than 1 × 10^{-7} M. Basic solutions have lesser concentration of H+ ions as compared to that of water. They have a concentration lesser than 1 × 10^{-7} M. A solution from pH range 1 to 6 will be acidic. A solution from pH rage 8-10 will be basic.
