Final answer:
The Dead Sea is a hypersaline basin located between Jordan and Israel. Despite its high salt concentration, new species of bacteria have been found thriving in its extreme conditions.
Step-by-step explanation:
The answer to your question is (a) Dead Sea.
The Dead Sea is a hypersaline basin located between Jordan and Israel. It is known for its extremely high salt concentration, which makes it a harsh environment for most living things. However, despite its challenging conditions, new species of bacteria, such as Halobacterium, Haloferax volcanii, Halorubrum sodomense, Halobaculum gomorrense, and Haloarcula marismortui, have been found thriving in the Dead Sea.
These salt-tolerant bacterial mats are able to survive in the Dead Sea due to their adaptations to high salt concentrations. They have evolved mechanisms to cope with the high osmotic pressure, maintain cellular homeostasis, and utilize the available resources in their unique and hostile ecosystem.
