Bacteriostatic
Explanation:
The antibiotics are the compounds which are used to treat the bacteria and are of two types: the bacteriostatic and bactericidal.
The bacteriostatic antibiotics are the antibiotics that do not kill the cells but they stop the reproduction of the bacteria and keep them in their stationary phase.
In the given question, since the antibiotic does not kill the cell but stops the doubling that is reproduction therefore the antibiotic is bacteriostatic.
Thus, bacteriostatic is correct.

Answer:
1.8 pounds of Nitrogen per year; (based on 1000 square feet per application) for cool season grasses.
Explanation:
The above application shows an average of 0.9 pounds of inorganic and organic nitrogen per 1000 square feet per application . Therefore not more than 0.9 pounds of nitrogen will be needed per application.And for a whole year 1.8 pounds of Nitrogen per year will be needed.
This calculation was based on 1000 per square.But most lawn are not 1000 per square, therefore calculation can be done using the 1000 per squares as the reference point .
AMMONIA and its solutions, AMMONIUM NITRATE AND UREA (which is organic source)<u>are the sources of this Nitrogen</u>.
Urea is non -explosive in nature and solid. However, ammonia and ammonium Nitrate are both explosive.
