At an optimum pH of 7.0, there are more molecules per minute in all amounts of substrate thus this pH is ideal for maximum growth. 5. Enzymes function most efficiently at the temperature of a typical cell, which is 37 degrees Celsius. Increases or decreases in temperature can significantly lower the reaction rate.
Disadvantages of aluminum in building cars include:
On average, aluminum is more expensive than steel, as much as two to three times.
Aluminum is not easily welded. If a steel door or panel suffers a crack, often it cam be welded back together easily, primed and repainted so its difficult to tell any body work has been performed. This cannot be done with aluminum. Steel also can be bent and shaped as needed.
Body shops and even dealer service centers are currently equipped for steel work with technicians skilled in the art of welding and steel fabrication. The cost of switching over to an infra structure designed specifically for all-aluminum vehicles or mass production of aluminum vehicles and components would be high.
Answer:
Independent Variable = Years
Dependent Variable = Number of Mobiles phone owners
Explanation:
Independent variables are plotted on x-axis and the dependent variables are plotted on y-axis.
In given graph the "Years" belong to x-axis hence, years are the independent variables.
Also, "Number of Mobile phones owners" belong to y-axis hence, this number is the dependent variable.
Answer:
Explanation:
2NO3, Ca2+
Spectator ions exists in both sides of the equation. These ions are present in both sides thus cancel out (they do not contribute to reaction...i.e. they only watch or spectate ;) )
