A serum calcium concentration of this range only means
that the cancer must be suspected to be a malignant one. So the nurse should
suspect that the malignancy of the cancer is what is causing the electrolyte imbalance
of the patient.
Cyanobacteria don't need oxygen to survive they produce oxygen. They where the first ever known organisms on the planet and they produced oxygen in the oceans which was absorbed by iron deposits and then once the iron had oxygen the ocean got the oxygen until it got into the atmosphere and Eukaryota bacteria evolved. So the answer would be: <span>They convert nitrates from the water into nitrogen gas (N2) that is released into the atmosphere.</span>
There were multiple theories of evolution prior to Charles Darwin's theory of evolution, some being from the antiquity, some just 300-200 years old.
One of the theories of evolution was the theory of hybrids. This theory was proposed by the great natural scientist Carl Linnaeus in 1744.
His theory was that initially God created small number of species, and placed those species on an isolated island. Over time, the created species started to breed between each other. That created numerous different hybrid offspring. These hybrids were actually new species, created by the breeding between the different species, and over time they developed into the numerous species we now of.
