Dandelion seeds are dispersed by the wind It uses the warmth water and light to grow The structure of the flower when it sets seed allows the lightness of the seed and its sail to be dispersed in the wind. They are spread by the wind. When the flower matures from its usual yellow, the seeds, sporting tiny white 'parachutes' are blown about by the wind - often for considerable distances. Because it's a sperm wind, birds, and humans Yes it can. they reproduce by forming tiny cells that can grow into new plants, <span>which are called spores.</span><span>

- The control group is the standard by which the experimental group is compared with.
- The variables are being tested for in the experimental group to see how they are changing .

Answer:
The correct answer is 1. EEG.
EEG or electroencephalography is a technique used to measure the electrical activity of the brain.
8 to 16 pairs of electrodes are placed on the scalp which record the electrical activity or impulses (in volts) generated by thousands of neurons or nerve cells present in the brain.
It provides the real-time imaging of the electrical activity of the brain.
The recorded impulses are first sent to the amplifier as the magnitude of the brain's electrical impulses is very low.
The amplifier then amplifies the results and show it on the screen in the form of voltage units.
