Explanation:
The answer is B: Sound waves cause parts of the ear to vibrate until the waves are converted to electrical signals, which are sent to the brain.
The local concentration of carbon dioxide in the atmosphere increases when rainforest is slashed and burned because there is less vegetation to use CO2 for photosynthesis.
<h3>WHAT IS PHOTOSYNTHESIS:</h3>
- Photosynthesis is the process whereby green plants obtain their food (glucose) using energy from sunlight.
- Green plants in an ecosystem absorb carbon dioxide (CO2) from the atmosphere as one of the reactants of photosynthesis.
Therefore, this means that the local concentration of carbon dioxide in the atmosphere increases when rainforest is slashed and burned because there is less vegetation to use CO2 for photosynthesis.

Answer:
The pressure of the gas increased (if temperature remained constant).
The Boyle's law supports this observation.
Explanation:
The initial measurements of the gas are given as;
volume = 100 L
Pressure = 300 kpa
The second measurement is given as;
Volume = 75 L
The second reading implies that the volume of the gas has decreased. If the temperature of the gas remained constant, then the pressure must have increased according to the Boyle's law;
At constant temperature, the pressure of a given mass of an ideal gas is inversely proportional to its volume.
FILTRATION When the substances in a mixture have different particle sizes, they are separated by filtration. The mixture is poured through a sieve or filter. The smaller particles slip through the holes, but the larger particles do not.p
