Answer:
If contain, the colorant stays, if not, it washes.
Explanation:
The ELISA inmmunoassay experiment consists on adding to an antibody a sample with a colorant, if the sample contains an antigen, it will stick to its proper antibody and te colorant will remain. If not, when the laboratory worker washes the sample after adding the sample, the colorant and the sample will be gone because there wasn´t an antigen on the sample that fitthe antibody. In that case, the result will be negative.
Basically everything would die off. All plants take in CO2 from the atmosphere, which is then used in photosynthesis creating glucose and oxygen. Oxygen is a definite need for us and then of course the plants are eaten and the glucose/carbon cycles through the food chain.
Since there isn't an unlimited amount of carbon available to us, we need the carbon cycle to replenish the stores.
