The lack of functional genes that mediate the nitrification process in bacteria attached to both Microcystins and Dolichospermum cells indicated that these two genera preferred ammonium (NH4-N). Dolichospermum cells obtained more available N through N2 fixation, which was expressed by high nitrogenase...
Also, cycads (a type of tropical plant that resembles a palm tree) produce special aboveground roots that harbor nitrogen-fixing cyanobacteria. By growing above the ground, the roots are exposed to sunlight, which the cyanobacteria require for growth. Nitrogen fixation by free-living bacteria in ...
Briefly explain the process of nitrogen fixation in the soil. Describe two variables that effect the rate of diffusion? Explain the process of hydrogen bonding. What are three ways in which humans affect the carbon cycle? Explain. What are the biological impacts of these actions? Explai...
Explain the importance of protein degradation.Protein:Protein is a large biomolecule that comprises several polypeptide chains. Proteins are essential in proper cell functioning, growth, and metabolism. Actin, keratin, albumin, globulin, and heme are some examples of proteins....
fixation of nutrients from the atmosphere for growth, for example the energetically costly process of nitrogen fixation from atmospheric N2, and the incorporation and availability of metals for use in enzymes to catalyze reactions. This may pose a problem for the life hypothesis proposed by Bains et...
It is a slow process. The nitrogen is mainly provided by the atmosphere and they make more than 80 percent of the air. The nitrogen can occur in the form of element or molecule. In the process of nitrogen fixation this nitrogen is changed into the other compounds of nitrogen. The ...
Explain the process of inhalation. Explain about lung cancer. Describe the condition which makes oxygen toxic. Explain the phenomenon of Carbon fixation. Describe the concept of chemical bonds and valence. Why should firefighters be concerned with carbon monoxide during firefighting? Explain the equation...
What are two environmental aspects of the Haber process? Explain. What is iron used for in the Haber process? Describe the Haber-Bosch process. Describe the process of nitrogen cycle. How does Haber Process utilize Le Chatelier's Principle to maximize the production of ammonia? The Haber-Bosch...
Briefly explain the process of nitrogen fixation in the soil. Explain the difference between an ionic bond and a covalent bond. What happened to the indicator as exhaled air bubbled through the solution? What caused this change? What is the purpose of correcting the oxygen volume by using...
