Answer:

C. Electroencephalography (EEG)

Explanation:

This is an electrophysioloical method of recoding the electrical activities in the brain. The process is non invasive and involves placing wires across different regions of the scalp. It measures the voltage fluctuations resulting from ionic current within the neurons of the brain. This helps to study the state of the brain and rule out disorders

Answer:

C) electroencephalograph (EEG)

Explanation:

The bunch of wires stuck to her scalp was to measure the ionic  differences(Na +/K+) in axoplasm of  her brain neuron, which when  sum up  from million of  neurons at different  electrode location on her scalp  generated electrical field.When this passes through the brain tissues and eventually to the scalp  it can be detected and  measured as spikes of brain activity on the monitor. This techniques is called EEG, and it is used to monitor electrical activities of the brain.

it is used for diagnosis of epilepsy,seizure, nacolepsy-sleep disorders etc.

Its operation principle is that any alteration from the usual spikes of electrical activities of the brain must be due to an anomaly in the brain's function.

Answer:speciation

Explanation: Speciation is the evolutionary process by which populations evolve to become distinct species.

Speciation may also be induced artificially, through animal husbandry, agriculture, or laboratory experiments.

The way that does not successfully classify protists is their size. Thus, the correct option is C.

<h3>What are Protists?</h3>

Protists may be defined as one of the diverse taxonomic groups and particularly a kingdom of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that generally include the protozoans, most algae, and often some fungi.

On the basis of the way that Protists reproduce, they can be subdivided into three types: Sexually reproducing protists, asexually reproducing protists, and conjugation-based.

On the basis of how protists get energy and food, they are again subdivided into three categories.

  • Animal-like protists: Heterotrophs that have the ability to move.
  • Plant-like protists: Autotrophs that have the ability of photosynthesis.
  • Fungi-like protists: Heterotrophs have cells with cell walls.

On the basis of the way that they move, they are subdivided into two types: Motile protists and non-motile protists. They generally move with the help of cilia, flagella, and pseudopodia.

Therefore, the size is not one of the following ways that protists are grouped. Thus, the correct option for this question is C.
