Answer:
endosymbiosis.
Explanation:
By the beginning of the 20th century, researchers thought that plastids and mitochondria could come from bacteria. These would have been ingested by primitive cells and live within them in symbiosis.
The Urinary bladder controls the elimination of urine from the body.
- The lower abdomen contains this triangle-shaped, hollow organ. Ligaments that are connected to the pelvic bones and other organs hold it in place.
- When storing pee, the bladder's walls relax and expand; when emptying urine through the urethra, they contract and flatten.
- The typical healthy adult bladder has a two to five-hour storage capacity of up to two cups of urine.
Three parts of bladder allow urine to be discharged:
- A pair of sphincter muscles. By tightly shutting around the bladder opening like a rubber band, these circular muscles assist prevent urine leakage.
- In the bladder's nerves. When it's time to urinate or empty the bladder, the nerves let the person know.
- Urethra. Urine can travel through this tube and leave the body. Urine leaks from the bladder as a result of the brain's tightening signal to the bladder muscles.

Hello good afternoon...God bless :) here is the answer to your following question...
Explanation:
Osmosis is important to cells because it allows them to maintain water homeostasis. The most important function of osmosis is stabilising the internal environment of an organism by keeping the water and intercellular fluids levels balanced. In all living organisms, nutrients and minerals make their way to the cells because of osmosis. This obviously is essential to the survival of a cell.
