There are microorganisms that are able to live in extreme environments under adverse conditions of pH, temperature and salinity. These microorganisms are classified as extremophiles. Within the group of extremophiles there are halophilic bacteria, which are those capable of living in extremely saline environments.
One biological factor that all living things are subject to suffer from is osmotic pressure. Halophilic microorganisms have developed mechanisms to adapt to saline environments where osmotic pressure acts with great intensity on individuals. These bacteria change the chemical composition of their membranes and also accumulate osmoprotective compounds in their cytoplasm to compensate for osmotic stress.

Answer:
See Explanation
Explanation:
1: Seeds provide a protective coat so that the plant can develop when it finds nice soil.
2: Seeds have pre-packaged foods sources.
3: Seeds are very easily dispersed by animals, wind, water, ect...
4: Seeds have the capability to survive without water.
Answer: A: Detecting and locating objects and moving animals in the water
Explanation:
Its used for sensing tiny vibrations in the water
Answer:
Symbiosis is a close relationship between two species in which at least one species benefits.
Explanation:
Natural selection can cause speciation, which increases the biodiversity of an ecosystem. Several bacterial colonies are placed on a petri dish that contains agar with antibiotics. After 24 hours, ninety percent of the original bacteria die, but the remaining ten percent survive and later reproduce.
