Answer:
retroviruses
Explanation:
Retrovirus have an enzyme known as reverse transcriptase which allows them to synthesize DNA from RNA going against the central dogma of life which is the synthesis of RNA from DNA. This phenomenon is called teminism.
Difference between nitrification and dentrification
Explanation:
Nitrification and denitrification are part of the nitrogen cycle
Nitrification is the process of conversion of ammonium to nitrate by nitrifying bacteria like Nitrobacter and Nitrosomonas
Denitrification is the process of reduction of nitrate to nitrogen gas by denitrifying bacteria like Pseudomonos, Lactobacillus etc.
Nitrifying bacteria are autotrophs and grows slowly and need aerobic condition. Denitrifying bacteria are hetertrophs and grows rapidly and need anaerobic conditions.
Nitrification requires a pH of about 6.5 to 8.0; denitrification takes place at 7.0 to 8.5
Nitrification provides soluble nitrates readily available in the soil to be easily absorbed by the roots.
Denitrification processes are used in wastewater or effluent treatment plants.
Plants get the carbon dioxide they need from the air through their leaves. It moves by diffusion through small holes in the underside of the leaf called stomata. These let carbon dioxide reach the other cells in the leaf, and also let the oxygen produced in photosynthesis leave the leaf easily.
