I promise I'll write it for you but plz tell me what exactly am I writing about it's alot of stuff what's the main topic
Three lines of evidence that support the endosymbiotic theory:
1. The presence of membrane- Organelles like mitochondria and plastids have their own cell membranes, just like a prokaryotic cell does,
2. The presence of DNA- Each of these organelles have its own DNA genome, like a bacteria's genome, but much smaller.
<span>3. Reproduction (division)-Multiplication of the organelles occurs just like in bacteria, by division.</span>
The phrase "terminally differentiated," as applied to mature neurons, means that they: Cannot divide mitotically to produce daughter cells.
Breathing is usually controlled subconsciously by the respiratory center at the base of the brain. Breathing continues during sleep and usually even when a person is unconscious. People can also control their breathing when they wish, for example during speech, singing, or voluntary breath holding.
Hope this helps:)
