Carbon dioxide and oxygen enter and leave the plant through the stomata, on the underside of leaves.

You can, the dry ice(solid form of carbon dioxide) will ultimately evaporate into carbon dioxide gas, and will then leave only the regular ice (frozen water). Because the dry ice will no longer exist, the regular ice will melt.
to allow the correct amount of oxygen to enter and leave the substance
The flame of a Bunsen burner that is yellow in color will leave a black carbon residue due to the incorrect mixture of oxygen into the flame. Because there is not enough oxygen for complete combustion, the carbon reside is left behind. When the Bunsen flame has a sufficient amount of oxygen mixed in, hence the 'roaring flame', it has a blue color and does not leave a carbon residue due to complete combustion of the acetylene gas.
The element is carbon. Organic chemistry revolves around carbon-containing compounds that have C-C or C-H bonds. Not all compounds that have carbon are classified as organic though, such as carbon dioxide.
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
Oxygen (Step 1:takes in carbon dioxide. Step 2:releases oxygen)
There are a number of gases that enter and leave the lungs - predominantly, humans Inspire (Breathe in) Oxygen and Expire (Breathe out) Carbon Dioxide. soo that is the answer init lool x
The red blood cells in your body contain oxygen and carbon dioxide. So, as the red blood cells travel through your bloodstream, the oxygen travels through to your heart, then your lungs, along with the oxygen.
guard cells and stomata.
Oxygen is brought into the blood, and carbon dioxide released from the blood, at the alveoli of the lungs. Gases diffuse across the alveolar membrane to enter or leave the blood.
Oxygen and carbon dioxide get into and out of cells via diffusion. The gases diffuse across the thin capillary wall, and then diffuse across the cell membrane.
The carbon dioxide is dissolved in your blood. The blood travels round the body, to the lungs. Oxygen and Carbon Dioxide are exchanged during breathing. The Carbon Dioxide is exhaled from the lungs, through the mouth.
Diffusion
Oxygen (O2) and Carbon Dioxide (CO2) =)
Oxygen must enter our blood and Carbon Dioxide must leave the blood through our lungs. They do so by diffusion between the cappillaries.
plants take in carbon dioxide and release oxygen
