Answer:
The lung
Explanation:
The model of the respiratory system made by Megan consists of two balloons. The first balloon stretched across the bottom of the bottle represents the diaphragm which contracts and relaxes to allow air in and out of the lungs. The balloon inside the bottle represents one lung.
Breathing in causes the balloon inside the bottle to be filled with air. This is preceded by the expansion of the diaphragm which makes the lungs to be filled with air. Breathing out causes a contraction of the diaphragm thus making the lungs to let out air.
Answer:
Sediment build up or the movement of water can transfer fossils to different places other than its original place.
Answer:
Explanation:
Activation energy is simply defined as the energy barrier that must be overcome for chemical reaction to take place. The lower the activation energy, the faster a reaction proceeds and vice versa.
A speed bump is a raided ridge on the road used to slow down the motion of a moving vehicle.
We can see that both activation energy and bump tends to slow down the rate of motion.
Therefore, the lower a bump, the faster a car will move. The lower the activation energy, the faster a chemical reaction will proceed.
Roads without bumps provides free movement and also, reactions without activation energy will proceed much faster.
