Homeostasis is a self-regulating technique by which systems
in the body maintain stability and tend to adjust to optimal conditions which
are essential for survival. Thereby, the role of homeostasis is to help the
body maintain constant internal environment. A good example of homeostasis
would be ‘drinking excess alcohol causes vomiting’.
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
Lividity can be defined as the typical bluish-purple discoloration of the skin after death. Rigor mortis can be defined as the postmortem state in which the muscles become stiff.
- After death, the stomach contains identifiable ingested foods within two hours.
- Rigor mortis is characterized by the stiffening of the body after death, which is caused by the absence of ATP in muscle tissues.
- Postmortem lividity or livor mortis is caused by the accumulation of blood in blood vessels (the lack of arterial pressure) as a result of gravity.
- The most relevant information to determine the time of death is the presence of lividity, rigor mortis, and/or stomach contents (Option c).
