The answer is; E
This shows that these organelles were once free-living organisms with their own mechanisms for reproduction which they have retained even after years of symbiotic relationship with the higher organisms. During their duplication, they also replicate their own DNA. Their DNA does not have histones (as opposed to the DNA in the nucleus of their host eukaryotic cell) similar to that of simple organisms such as bacteria.
The runners muscles have accumulated lactic acid.
Although the total distance the impulse travels in the reflex arc is less than 3 meters. the time taken is more than 0.04 seconds and the time taken is more than expected because of Synapses or due to gaps between neurons.
Diagram displays the whole reflex arcs from the tip of the finger to the spinal cord and then back out to a closer muscle, possibly in the forearm or the arm. Because the signal doesn't have to go all the way back to the finger, the total distance is less than 3 meters. Considering that it just travels back a portion of the way, less than 3 meters, it takes. Let's see, it takes more than twice as long, therefore the query makes us think about why the delay. Where is the hold-up what is happening there, and the key to this is that the gray matter of the spinal cord doesn't truly contain mylin, despite the fact that we said it- accelerates electrical conduction through the axon in the nerves of the extremities. Mylin has a whitish color, which contributes to the white matter's appearance of whitishness. Thus, the electrical signal becomes slower.
