Answer:
EEG
Explanation:
EEG or electroencephalography is a technique that measures the electrical activity of brain.
For measuring electrical activity, electrodes are attached to her scalp. An abnormal activity of brain such as epilepsy can also be recorded by EEG.
The brain is an electrical system as it is a network of neurons. Neurons communicate with each other via electrical signal. The more electrical signals corresponds to more brain activity.
The electrodes of an EEG record the electrical changes occurring in thousands of neurons.
The signal received by the electrodes is amplified by an amplifier. Various maps of brain activity is generated by a computer.

Explanation:
Answer:
Replication
Explanation:
The 3 main principles of experimental deisgn
1. Randomisation
2. Replication
3. Blocking
Replication
This has different definition. It is when a researcher repeats that is replicate research findings through correct use of operational definitions, procedures, etc.
A good research mut be replicated and it must result in the same or similar in terms of findings each time the experiment is performed.
It also implies that the treatment used in an experiment was used more than once in an experiment. It because allows us to estimate the inherent variability in the data. This allows us to know and judge if an observed difference in treatment was as a result that is it could be due to chance variation.
Replication is very important because when we have one experiment or treatments once, we would not know if the observed difference is due to the treatments or just random variability. But replication helps you to know the reason for the observed differences.
Answer:
A civilization may fall if an attack, shortage of food, or war happens. A disagreement in the government or disease may also make the civilization fall too.
Explanation:
The total population during the civil war were around 22,100,000 (71%) in the Union and 9,100,000 (29%) in the CSA. The Union had twice as many soldiers and many more firearms, but the CSA had more slaves. Thank you for posting your question here at brainly. I hope the answer will help you.
