1. Remember the label from Garden Soil Inoculant said: "Helps fix nitrogen in soil. Boost pea and bean yields with Garden Soil Inoculant. Simply shake granules into furrows as you plant. It contains nitrogen-fixing bacteria to promote stronger root systems and larger harvests. Easy-to-use sprinkler top makes application a snap. 8.7-oz. container treats a 150 row." This product is recommended for growing plants such as beans and peas, for all of the following reasons EXCEPT a. Plants such as beans and peas can use nitrogen gas as their nitrogen source b. Plants such as beans and peas produce root nodules that harbor bacteria c. Plants such as beans and peas form symbiotic relationships with the bacteria in the inoculant product. d. Plants such as beans and peas are legumes 2. Molecular nitrogen (nitrogen gas) makes up 78% of the Earth's atmosphere but is unavailable for use by all organisms except for some nitrogen-fixing (choose all correct answers.) a. bacteria b. eukaryotes c. protists d. fungi e. cyanobacteria f. prokaryotes 3. covalent Nitrogen gas consists of two nitrogen atoms bound to one another by (number) bonds. A great deal of energy is required to break these bonds, which is why nitrogen gas is a chemically inert molecule. The organisms that can fix-nitrogen produce the enzyme This enzyme breaks the bonds that hold the two nitrogen atoms together.Explanation / Answer
1) This product is recommended for growing plants such as beans and peas, for all of the following reasons EXCEPT:
A) Plants such as beans and peas can use nitrogen gas as their nitrogen source.
2) Molecular nitrogen (nitrogen gas) makes up 78% of the Earth’s atmosphere, but is unavailable for use by all organisms except for some nitrogen-fixing ____.
A) Bacteria
D) Fungi
E) Cyanobacteria
3) Nitrogen gas consists of two nitrogen atoms bound to one another by (number) three covalent bonds. A great deal of energy is required to break these bonds, which is why nitrogen gas is a chemically inert molecule. The organisms that can fix-nitrogen produce the enzyme Mo-nitrogenase. This enzyme breaks the bonds that hold the two nitrogen atoms together.
