Answer:

Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon back into the atmosphere.

Explanation:

The first option clearly expresses the relationship between photosynthesis and cellular respiration.

Cellular respiration releases carbon back into the atmosphere whereas photosynthesis removes the carbon from the atmosphere.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water.

In cellular respiration, the product of the photosynthesis is used by organisms to produce energy.

In which step of a four-stroke engine cycle does the car release CO2, H2O, and CO?

In-s [12.5K]

Answer:

$\boxed{\text{exhaust stroke}}$

Explanation:

The four strokes are

Intake: The mixture of air and fuel enters the cylinder.
Compression: The mixture is compressed by a factor of about 11.
Ignition: A spark ignites the fuel, which burns and produces CO₂, CO, and H₂O.
Exhaust: The combustion products are expelled from the cylinder.

$\text{The cylinder releases CO$_{2}$, CO, and H$_{2}$O during the }\boxed{\textbf{exhaust stroke}}$

When 10g of calcium carbonate is heated,4.4g of carbon dioxide escape out. The amount of residue left is:

Maslowich

The dissociation of calcium carbonate, CaCO3, to simpler compounds can be expressed as,
CaCO3 --> CaO + CO2
The precipitate is CaO and its amount is calculated through the difference which will give us the answer of 5.6 g.
