Answer:
The bubbles contain <u><em>oxygen</em></u>. This happens due to <u><em>photosynthesis</em></u>.
Explanation:
In photosynthesis of submerse water plants, oxygen emission occurs in form of bubbles which are released from the stomata. Usually the oxygen discharge is in form of regular bubble series. As the light levels are increased there is an increase in oxygen (bubble) production from photosynthesis of the plant.

Answer:
Is used to prevent contamination from pathogens.
Explanation:
Pathogens are disease causing organisms. In a clinical setting or even in the laboratory, a person has to use the strictest means of disease prevention and even re-infection (for patients). Aseptic technique is important to protect yourself, other workers and patients from infection and from the spread of pathogens. It effectively maximizes the presence of pathogens and totally eliminate them. This is possible from simple measures like using your PPE which must all be sterile. From your gloves, gowns etc to your equipments used during any procedure. Also disinfection of your work place is important too either by concurrent disinfection or intermittent disinfection.
The Permian period, which ended in the largest mass extinction the Earth has ever known, began about 299 million years ago. The emerging supercontinent of Pangaea presented severe extremes of climate and environment due to its vast size. The south was cold and arid, with much of the region frozen under ice caps. Northern areas suffered increasingly from intense heat and great seasonal fluctuations between wet and dry conditions. The lush swamp forests of the Carboniferous were gradually replaced by conifers, seed ferns, and other drought-resistant plants.
Early reptiles were well placed to capitalize on the new environment. Shielded by their thicker, moisture-retaining skins, they moved in where amphibians had previously held sway. Over time, they became ideally suited to the desert-type habitats in which they thrive today.
