Answer:
• Increase temperature
• Increase concentration-Increase concentration of the Silver nitrate or of the copper.
• Increase surface area-Grind the copper into powder of break it up into smaller pieces.
Answer:
E. are found in nitrogen-fixing cyanobacteria AND are used to protect nitrogenase.
Explanation:
Heterocysts are specialized cellular compartments found in nitrogen fixing cyanobacteria. They provide the ideal anaerobic environment for nitrogen fixation since nitrogenase enzyme cant work in presence of oxygen. Hence, in a cyanobacteria both the oxygen requiring photosynthesis process and the oxygen sensitive nitrogen fixation process takes place simultaneously.
Heterocysts have an additional cell wall made of glycolipid that provides a hydrophobic barrier to oxygen. They are involved in production of nitrogenase and other proteins that are required for nitrogen fixation. They also degrade photosystem II which is responsible for producing oxygen and produce proteins which remove any remaining oxygen.
D). Beliefs are not scientific.
This was to gain more support for Allied efforts in the
Second World War to ensure their victory.
By utilizing media, propaganda to support the war went into full swing
as companies lent their efforts to achieve that end. They convinced people to buy war bonds as
well as boost morale for the troops.
