Because their tissues are <u>isotonic</u> with the marine environment, jellyfish are called as <u>osmoconformers</u>.
EXPLANATION:
Osmoconformers are the marine organisms that keep their internal fluid isotonic to that of their environment. They maintain a constant internal environment which is osmotic to their external environment. This means the osmotic pressure of the cells of an organism is equal to the osmotic pressure of their surrounding.
Because their tissue are hypotonicwith marine environment Jellyfish are Marine habitat. The solution inside the cell contain fewer solute than outside solution ( marine water) The jellyfish cell losses water through osmosis. In addition these cells gain electrolytes by diffusion.
if sex cells were identical, there won't be genetics variations and we will just all be identical to our parents. genetic variation allows us to better adapt and survive
