Tuberculosis (TB) is caused by Mycobacterium tuberculosis, slow-growing bacteria that thrive in areas of the body that are rich in blood and oxygen, such as the lungs.uberculosis (TB) is caused by Mycobacterium tuberculosis, slow-growing bacteria that thrive in areas of the body that are rich in blood and oxygen, such as the lungs.
Why does water have a maximum density at +4 deg C ? Is water unique in having this peak in density not at an extremity of the temperature range of a single (i.e. liquid in the case of water) state? Is this property of water the single most important reason for life to have evolved on this planet?
The density of pure water is 1000 kg/m 3. Ocean water is more dense because of the salt in it. Density of ocean water at the sea surface is about 1027 kg/m 3. This is a simple density-depth ocean water profile.
