Bacteria are tiny, one-celled organisms that can be found almost everywhere, in the deepest oceans, in the thickest soil, and up to 90,000 feet in the atmosphere. There are many kinds of bacteria, some which cause deadly diseases and some which are helpful to man.
Those which are harmful cause diseases in man, animals, and plants. They can cause food to spoil, even poisoning people who eat them.
But there are a great many bacteria that man and nature use in helpful ways. For example, bacteria play an important role in making buttermilk, sauerkraut, cheese, and vinegar by causing a chemical change called fermentation. Bacteria also attack dead plants and animals, and break them down into nourishment for the soil.
Bacteria are even used to purify water in sewer treatment plants!
Yes, Parafilm allows for limited gas exchange due to its semi-permeable nature.
Gas exchange can also be referred to as respiration. This process involves the uptake of oxygen and release of carbon dioxide in living organisms. It occurs in specialized organs such as the lungs in mammals and gills in fish.
Gas exchange occurs in the alveoli of the lungs. These tiny air sacs are surrounded by capillaries where oxygen from the air can enter the bloodstream and carbon dioxide can be removed from the blood.
Alveoli in the lungs provide the greatest surface area for gas exchange in the body. They are tiny air sacs that are surrounded by capillaries where oxygen and carbon dioxide are exchanged during respiration. The numerous alveoli increase the total surface area available for this gas exchange process.
Book lungs are the respiratory structures of arachnids that have pages or layers that facilitate the exchange of oxygen and carbon dioxide. They are located in the abdomen and work by using tiny plates to maximize surface area for gas exchange.

The exchange of genetic material from bacteria to bacteria through sexual reproduction.
Gas exchange is a function of respiration not digestion.
Alveoli is where gas exchange occurs.
animals dont really need nitrogen but for plants, they need nitrogen and they get nitrogen usually in the form of nitrates or bacteria protein, by the work of nitrifying bacteria, putrefying bacteria and nitrogen fixing bacteria
Pili are filaments that help bacteria stick to the surface and exchange plasmid through conjugation.
Bacteria change genetic information with each through conjugation.
Nitrogen from the air is absorbed by the bacteria present in the root nodules of the plant in a symbiotic relationship in which the bacteria provide nitrogen for the soybean's growth in exchange for some nutrients (mostly sugars) that flow in the plant's roots and that the bacteria need for its own growth.
The exchange surfaces are moist.
gaseous exchange
gas exchange occurs between the thin walls of the alveoli and the thin walls of the capillaries
