Afetus is said to reach full term around weeks.
a. 27-30
b. 30-34
c. 37-40
d. 40-44

The correct answer is (c) 37-40

The baby is said to be full term baby if the  baby is born in between 37 weeks to 40 weeks. The gestation period of humans is 9 months. The fetus must be born in between 37-40 weeks of pregnancy. At this period of time the fetus is fully mature and has developed organs. Once the fetus is ready to face the outer environment, the organs like heart, kidney must be fully developed to perform its function.

step 1 ammonium can be absorbed by plants, but some is converted into nitrates which are better for plants to absorb. this is called nitrification. 2. step 2 the deer eats the plants and uses the nitrogen-containing proteins for cell growth. 3. step 3 bacteria in the soil conduct nitrogen fixation to convert nitrogen gas from the atmosphere into ammonium. 4. step 4 some of the nitrates are absorbed back into plants, but denitrification breaks down the nitrates into nitrogen gas released back into the atmosphere. 5. step 5 nitrogen is found in the urine, which gets broken down into ammonium through the process of ammonification. 6. step 6 plants absorb the ammonium and begin assimilation, the process to add the nitrogen to protein.
