B
Explanation:
consists of only one nutrients
Cyanobacterial species are thought to be the first photosynthetic organisms. These unicellular bacteria occur in Maine environments, the presence of water acted as a sun-screen, preventing the denaturation of photosynthetic hardware by exposure to high uv. This high volume of Cyanobacteria in the oceans produced vast quantities of oxygen - this allowed organisms to grow in size a their metabolic demands could now be met. At one point the large concentrations of oxygen lead to gigantism. following the first endosymbiotic event, where a cyanobacterial cell became enslaved in a bacterial cell, photosynthetic eukaryotes were 'born'. This lead to the formation of both terrestrial and marine chloroxygenic organisms.
Yes, the human body is composed of approximately 60% of water. The given statement is true.
Water is essential for human health and for the survival of life on earth.
It keeps them alive, stale and healthy by providing oxygen and chief nutrients to the body.
It lubricates joints, knees and also removes waste materials from the kidney, and keeps them clean.
In adult humans, there is approximately 60% of water in their bodies.
The concentration of water is more in lean tissues than in fat tissues.
Women's bodies have more fats than men and water makes up only 55% of their bodies.
