Answer: Most jellies use a form of jet propulsion to move through seawater. ... This is what most jellyfish do. They squeeze their bodies in order to push jets of water from the bottom of their bodies to propel the jellyfish forward. Now check out another method of jellyfish propulsion, used by the comb jellyfish.....Aequorea jellies glow with a bioluminescent protein used in the biotechnology industry. ... Bioluminescence is light produced by a chemical process within a living organism. The glow occurs when a substance called luciferin reacts with oxygen. This releases energy, and light is emitted....Jellyfish seem to blend in with their environment, undulating gently with the ocean's currents, and with good reason: Their bodies are made up of as much as 98 percent water, says How Stuff Works. When they wash ashore, they can disappear after just a few hours as their bodies evaporate into the air.
Jellyfish actually do not swim. They squeeze their body basically creating a force of water underneath them to move upwards Usually they will swim with the tide or current of the water! So if the water is flowing to the left They will move left This is because they have to bone structure to help them move where they wanna go
Leading into the next question... they actually do evaporate most times but not often If left out in the sun, they can evaporate due to extreme sunlight because they are 98% water!
And jellyfish glow due to this bio molecule thing. I forgot what it’s called but it reflects on to them and recta to oxygen
"The endocrine system is made up of glands that make hormones. Hormones are the body's chemical messengers. They carry information and instructions from one set of cells to another"
If this is for the scientific process unit, the answer is passing laws to prevent certain types of scientific research. I know because I had this question in biology.
