If the doctor recommends dialysis
for someone who has kidney disease and he goes for a home-treatment option, he most
likely chose hemodialysis. Home hemodialysis (HHD) is the option that offers
freedom to be treated outside of the dialysis center.
A is a possible answer as it refers to an increase of temperature; this is what global warming is (the raise of earth’s temperature)
Answer:
D. marks transformation of nitrogen (N₂) from the atmosphere to ammonium (NH₄ plus) by bacteria.
Explanation:
The nitrogen cycle is a biogeochemical cycle which involves transformation of atmoshperic nitrogen into many chemical forms including nitrite (NO2), nitrates (NO3) and ammonium (NH4).
The process of nitrogen cycle starts with the process of nitrogen fixation. In this process several nitrogen fixation bacteria such as cyno bacteria converts the atmospheric nitrogen into ammonium (NH4) in the soil. The resultant ammonium (NH4) can be directly used by plants or transform into nitrites or nitrates through nitrification process.
Hence, the correct option is D.
