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.
Question 1 is false and question 2 is A
Answer: promoting the rapid resynthesis of ATP, by the action of creatine kinase.
Explanation:
Adenosine triphosphate (ATP) is the main form of chemical energy, its hydrolysis remaining highly exergonic. The maintenance of cellular homeostasis mechanisms, that adjust the generation processes of ATP, responds to the energy demand.
Creatine phosphate (CrP) was discovered in 1927 in the muscle tissue. Free creatine (Cr) is generated from the breakage of (CrP) during muscle contraction. Since the PCr / CK (Creatine kinase) system has a high rate of ATP generation, it is particularly important in situations of high metabolic demand, such as high-intensity physical exercise, when the ATP utilization rate exceeds its generation capacity by other metabolic pathways.
Answer:
Option D, Tdap today; Td in 4 weeks; Td 6 months after the second dose
Explanation:
In general, Tdap is given before Td to all those adults who have never been administered with Tdap earlier.
Also as per the publication of CDC, any individual who is of 7 years or older than this and has never been vaccinated by Td needs following schedule of medication
a) First primary dose
b) After the first primary dose the second primary dose of Td must be given in 4 weeks and
c) The third primary dose must be given after 6 to 12 months.
Hence, option D is correct
