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:
Explanation:
Detergent enzyme used because The positively charged sodium ions in the salt help protect the negatively charged phosphate groups that run along the backbone of the DNA. A detergent is then added. The detergent breaks down the lipids in the cell membrane and nuclei. DNA is released as these membranes are disrupted.
Proteases catalyze the breakdown of contaminating proteins present in the solution to its component amino acids. It also degrades any nucleases and/or enzymes that may be present in the sample. This is of vital importance since these chemical compounds can attack and destroy the nucleic acids in your sample.
Slabs of ocean floor return to the mantle in subduction zones.
The answer is 5.1 because the nucleus will work faster
Answer: The statement is false
Explanation: A codon consists of three nucleotides instead of four. Codons are triplets of nucleotides on an mRNA molecule that code for specific amino acids. Each amino acids are specified by at least one codon. Some amino acids are specified by one codon, some are specified by two or more codons. The phenomenon whereby more than one codon specifies one amino acid is known as the degeneracy of the codons.
