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.

Answer:
The indigenous 'medicine man' flees seeing Dr. Campbell because both Dr Campbell and the medicine man, were in conflict with each other.
Explanation:
'Medicine Man' is a movie directed by John McTiernan, starring Sean Connery(as Dr. Robert Campbell) and Lorraine Bracco(as Dr. Rae Crane). The film is about Dr. Campbell who sets into the forest of Amazon and finds the cure to cancer.
The Medicine man is the one who informed Dr. Campbell about the flowers containing 'ju-ju' (powers to heal). But after Campbell cured a little boy having gas by 'alka-seltzer', they both were in conflict of each other.
So, when Dr. Campbell showed up with the man and a little boy suffering from malignant neoplasms at the medicine man doorsteps, the indigenous medicine man flees from there.
Answer:
D) that geographically isolated groups of dogs may be selected for quite different traits, resulting in a different dog breed
Explanation:
Artificial selection is a type of selective breeding made by humans in which offspring with desired traits are selected. Modern dogs evolved by artificial selection. Dog breeding began around 30,000 years ago from selective breeding of wolves that were separated from their original population and bred to produce dogs with desired traits (especially, loss of aggressive behavior). Purebred are reproductively isolated groups of dogs originated from the same lineage (i.e., the same common ancestor for each group), that never mated with another dog breed.
Explanation:
The breakdown of glucose.
During glycolysis, enzymes act on the substrate, glucose. The covalent bonds of the macromolecule contain energy that is released and stored within ATP.
Glycolysis occurs in the cytoplasm; here, 2 molecules of ATP are used to cleave glucose into 2 pyruvates, 4 ATP and 2 electron carrying NADH molecules.
Further Explanation:
In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’ or Citric acid cycle via the oxidization of pyruvate( through the process of glycolysis in the cytoplasm).
overall: C6H12O6 (glucose) + 6 O2 → 6 CO2 + 6 H2O + ≈38 ATP
