Common cold is caused by a virus. Antibiotics work on living things (anti-life) and viruses are non-living.
Since oceans cover 71% of the Earth’s surface, understanding what the seafloor looks like, and where different processes, such as ocean currents are active, is hugely important. Mapping the seafloor helps to work out things like where different types of fish live, where resources may be, such as rare metals and fossil fuels, and whether there is a risk of underwater landslides happening that might cause a tsunami. Mapping the seafloor is very challenging, because some cannot use the same techniques that some would use on land. To map the deep ocean, there's a tool used called a multibeam echo-sounder, which is attached to a ship or a submarine vessel.
Answer:
The ocean produces oxygen through the plants (phytoplankton, kelp, and algal plankton) that live in it. These plants produce oxygen as a byproduct of photosynthesis, a process which converts carbon dioxide and sunlight into sugars the organism can use for energy.
Hope it helps you, tell me if im wrong pls, BE SAFE! :D
