Nitrogen, even though makes for about 78% of our atmosphere, and is by far the most abundant gas in it, we can not use it because it can not be taken out of the atmosphere as it is. If we take nitrogen in the form as it is in the atmosphere it is useless for both humans and plants. It has to go through a process of ''fixation'' first before we can actually use it in our food.
Because whatever grows there, dies there, and the nutrients remain there. Since wetlands are mostly flat with stagnant or slow moving water. The wetness also keeps the nutrients in place, unlike dry places where the nutrients can be blown away or eroded by water
Interruption of blood supply to brain is caused by cerebral hemorrhage.
It would be “Upwelling Currents” this is a is vertical current to the coastline, and it brings up nutrients from the bottom of the sea floor, to the ocean surface. (Also that explains why the water is cold)
Somatic mutations are acquired after birth in non-reproductive cells. These changes occur in only certain cells of the body and can be caused by tobacco use, ultraviolet radiation, viruses, chemicals and age. Acquired mutations are the most common cause of cancer.
Humans experience many somatic mutations over a lifetime, and the human body is normally able to correct most of these changes. This is why there is only a small chance of one mutation causing cancer. It normally takes many mutations over a lifetime to cause cancer. This is why older people are the most likely group to get cancer, as they have had more chances for mutations to build up.
