A punnet square can be described as a diagram which is made to predict the genotype as well as the phenotypes of the offsprings of a cross.
To study the epistatis nature of the pigmentation in bear, a punnet square was made and the results of the punnet square are shown above.
The results of the punnet square show that the cross between two bears will have the chances of producing 9/16 black bears, 3/16 brown bears and 4/16 white bears.
Answer:
25% type A, 25% type B, 25% type AB, 25% type O
If you put it into a punnett square:
B O
A AB AO
O BO OO
you get 25% for each phenotype
B. bacteria that convert ammonia into nitrites and nitrates are found in the soil
This statement best demonstrates a way that the geo-sphere is involved in the nitrogen cycle.
A nitrogen cycle is defined as the movement of nitrogen between the atmosphere, biosphere, and geo-sphere in different forms. Ammonia is converted to nitrates by nitrifying bacteria in the soil. Then the plants absorb these nitrates from the soil and use these to build up proteins.
