Answer:
A. It allows plants to use nitrogen to grow.
Explanation:
However, plants can't directly use nitrogen to grow. The bacteria need to convert atmospheric nitrogen ( N2 gas) into a form that plants can use.
Nitrogen fixation is a symbiotic relationship between plants and microorganisms of nitrogen fixers, which in the process of symbiosis perform the binding of nitrogen, which enters the earth from the air (atmosphere).
It is a reduction process of converting the gaseous form of nitrogen from the air into the ammonia form that is available to plants.
They release CO2 (just like us, when we breathe). But, when plants are photosynthesizing. They release the oxygen through the same pores that allow the CO2 to enter their leaf cells.
Temperature should it be drawn to 600°-650° Fahrenheit for the newly made spring has been hardened
- Hammer, sear, and trigger are the three main parts of a trigger mechanism.
- . Single-stage trigger is used on the Winchester Model 94 and Marlin Model 336 rifle.
- Lapping is the process called that entails rubbing minute amounts of metal from surfaces that must be precision-finished.
- . Gray to dark blue color would be observe if we achieved the desired drawing temperature of 600-650° Fahrenheit.
- Thermocouple pyrometer is the most common instrument for measuring high temperatures in heat-treating furnaces.
- Cherry to bright cherry color would be observe by reaching the temperature of 1,400°-1,500° Fahrenheit.
- Once the newly made spring has been hardened 600° -650° Fahrenheit temperature would observe.

Answer:
Equal amounts of DNA contain equal proportions of nitrogenous bases.
Explanation:
According to Chargaff's rule, the nitrogenous base pairs (Purines and pyrimidines) have an equal ratio (1:1) in the DNA of all the organisms. More precisely, the amount of adenine is equal to thymine and the amount of guanine is equal to cytosine in the DNA of all the organism. A-T base pair has two H-bonds while G-C base pair has three H-bonds.
