I think the correct answer is B hope it helped
Answer:
17m/s
Explanation:
Given parameters:
Speed of the bird = 12.5m/s
Speed of the wind = 4.5m/s
Unknown:
Speed of the bird when it flies with the wind = ?
Solution:
The speed of the bird when it flies with the wind is the sum of the speed of the bird and the speed of the wind.
Speed of the bird with wind = 12.5m/s + 4.5m/s = 17m/s
The answer is <span>B. The type of fertilizer.</span>
<span>An independent variable is variable that is not affected in the
experiment. It is what experimenter controls. On the other side, a dependent
variable is called dependent because it depends on the independent variables.
It is what is affected during the experiment.
In this case, the growth of pea plants depends on different types of
fertilizer. So, the growth of pea plants is the dependent variable and different
type of fertilizer is the independent variable.</span>
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.
