Which of the following substitutes can reduce air pollution. a. using a bike instead of a car b. using dumps instead of landfills c. using coal instead of oil d. fireplaces instead of a wind farms

The correct answer is option A

Any undesirable particles or substance in the air is responsible to cause air pollution. This can be reduced using certain ways.

By using bike instead of using car is less harmful as compared to that of car. The amount of pollutant released into the environment by car is more as compared that of bike. The amount of harmful gases like carbon dioxide, sulfur dioxide, nitrogen oxide from bike is less as compared to that of car.

the bald eagle got 50 because everything gets 10% of what they consume and since 50 is ten % of 500 hundred that means the   grasshopper had to have consumed a plant with 5,000 calories of energy

the answer is; comparing the frequency of collisions with and without the device

this makes the anti-collision system an independent variable and the collisions a dependent variable. if there are fewer collisions with an anti-collision system that without, then it can be stated that the system is a success. essentially, collisions under an anti-collision system are compared with the frequency of collisions by cars with the human drivers.
