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.
Electroencephalography is an electrophysiological monitoring method to test or record brain activity.

Because of the small fillaments.
<span>It is a common misconception that elephants existed the same time as the dinosaurs did when in fact they have evolved 3 or 5 million years after these creatures.
The tusks of the elephant would probably be the structure not present in early elephants. It is only through evolution that these tusks grew. Some scientists have hypothesized that these tusks develop from the elephants' incisors.

Answer: B, Meiosis I
Explanation:
During meiosis I, genetic material halves, and you get 2 haploid cells (n) from a diploid cell (2n). Those divide again during meiosis II to form 4 different haploid cells.
DNA replicates during interphase and starting at meiosis I, 2n homolog chromosomes attach to form n tetrads. Those tetrads align in the cellular equator during metaphase I and then separate, moving to opposite poles during anaphase I. Each cell formed receives a copy of each chromosome and then divides in a process similar to mitosis during meiosis II.
