Chromatography is a laboratory technique for the separation of mixture. It contains two components:
Stationary phase- substance that is fixed inside the column
Mobile phase- substance that is moving through the column.
Analyte is the mixture that has to be separated by chromatography.
When both are added to the column, mobile phase and analyte, components of the analyte will adhere to the stationary phase at different level and as a result travel at different speeds through the stationary phase as the mobile phase flows through it. The components that adhere more strongly to the stationary phase travel more slowly compared to those with a weaker adhesion. So, chromatography separate substances based on their adhesion for stationary phase.
The correct answer is B: Time-consuming process of listing endangered species.
It is an example of a failed attempt to reintroduce clapper rails in California.
The California clapper rail is noted as an endangered species.
Endangered species are plants and animals that are in close danger of being extinct.
The theory was that physical changes in organisms during their lifetime such as greater development of an organ or part through increased use could be transmitted to their offspring.
The answer is through facilitated diffusion. It is then called as the transport of substances in a biological membrane from a higher concentration to a lower concentration area though carrier proteins. Hope this is the right answer and would be of help.
