Enzymes are biological molecules (typically proteins) that significantly speed up the rate of virtually all of the chemical reactions that take place within cells. They are vital for life and serve a wide range of important functions in the body, such as aiding in digestion and metabolism.
Answer:
It adjusts to different oxygen levels.
The cytochrome bo branch operates when E coli is growing rapidly with good aeration.
The cytochrome bd branch operates at low oxygen conditions. It is located in the outer membrane.
Explanation:
Electron transport chains of Escherichia coli are composed of different dehydrogenase and terminal reductase which is linked by quinones. It adjusts to different oxygen level because Oxygen is preferred electron acceptor and represses the terminal reductase of anaerobic.
Answer: cytokinesis
Explanation:
In animal cells, cytokinesis is achieved when a contractile ring of the cell microtubules form a cleavage furrow that divides the cell membrane into half.
Answer:
Resistance = 30 Ω
Explanation:
The resistance of an electric circuit = 
voltage = 24V
current (I) = 0.80A
Therefore, R = 
R = 30 ohms
Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current's direction and speed depend on the shoreline and the ocean floor.
