Mila [183]

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.

The fourth ribs is use for determining the age of skeletal remains.

Explanation:

The human pelvis is use to determine the biological sex of skeletal remains. The woman pelvis is wider than man's and it provide space for birth canal.

The fourth ribs is use to estimate the age of skeletal remains as the cartilage between the ribs and sternum gradually turn as time goes on. The features of the head can also be use to estimate the age of skeletal remains.
