What are cells?Cells are the fundamental building blocks of all life. Trillions of cells make up the organisms' body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic molecules found in all cells.
Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.
Like the walls of a house, all cells are surrounded by a structure called the cell membrane, which serves as a clear boundary between the cell's internal and external environments.
Thus, cells are the basic unit of structure of all organisms.

When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between which two reservoirs of the carbon cycle? * A. Hydrosphere and biosphere B. Geosphere/lithosphere and atmosphere C. Atmosphere and biosphere D. Hydrosphere and geosphere/lithosphere
Answer:
B
Explanation:
When humans dig-up fossil fuels and burn them to power the modern world, carbon flows between the Geosphere/lithosphere and the atmosphere.
Both the geosphere and the atmosphere represent important reservoirs of carbon. The digging-up of fossil fuels, otherwise known as exploration, is carried out in the geosphere or the lithosphere part of the earth. For example, crude oil is obtained deep from the ground. When the fuels are burned, they release carbon in the form of carbon dioxide into the atmosphere.
Hence, it can be concluded that carbon flows from the geosphere/lithosphere part of the earth to the atmospheric portion of the earth when fossil fuels are burned.

Some are even involved in protecting the skin from many infections.
They are also helpful in the production of vitamin K and have an important role to play in the functioning of immune system. One of the most common bacteria which are helpful for humans is Escherichia coli. This bacteria is associated with the process of digestion. It is present in the large intestine where the maximum digestion takes place. These bacteria release enzymes which help in the process of digestion and synthesis of various vitamins and nutrients. Beneficial bacteria are also very helpful for the pregnant women. They reduce the chances of postpartum complications and also protects the baby from fungal infections.
