Answer:
Electroencephalogram
Explanation:
In the cerebral cortex, cell bodies (soma) and dendrites produce the synaptic potentials that create an electrical activity that can be measured by electrodes placed on the scalp resulting in an <u>Electroencephalogram</u>.
a test or record of brain activity produced by electroencephalography.

Answer:
Option (1).
Explanation:
DNA (deoxyribo nucleic acid ) is the genetic material present in all the organisms except some viruses. DNA structure follows the Chargaff's rule.
Accoprding to Chargaff's rule, the ratio of purines to pyrimidines in a DNA molecule is equal to 1. The amount of guanine is nearly equal to the amount of cytosine whereas the amount of thymine is nearly equal to the amount of adenine.
Thus, the correct answer is option (1).
