Eukaryotic cells are theorized to have evolved from prokaryotes called the endosymbiotic theory. This explains that the most primitive eukaryotic cell engulfed a prokaryotic cell (by the process of phagocytosis) that is capable of cellular respiration and another prokaryotic cell that is capable of photosynthesis. These prokaryotic cells eventually became organelles and these organelles are the mitochondria and the chloroplast.
Answer:
Either (1.) Fossils or (2) Radiometric dating.
Explanation:
Fossils are an obvious answer to this, but radiometric dating is the method most scientists use to find the age of rocks. Radioactive isotopes break down predictably, so the farther along this process is, the older the rock is.
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.
