Because you could easily contaminate the results of the urine if you don't follow exactly what the strict rules dictate This could be a very dangerous thing because if you contaminate the results, then other doctors would think that the patient has some disease that needs to be taken care of which in reality they do not. The patient could also have to go through things or waste money on things that they don't need to because there was something in the urine that wasn't supposed to be there which was added because they didn't follow the strict rules. Then the doctor who contaminated it could be sued for malpractice which is never a good thing.
Glycolysis, Krebs cycle, electron transport chain
The best answer is E) All of the above.
The littoral zone is the region where the land meets a body of water, and although the exact definition can vary, it generally includes land that is always dry and a region that is always submerged. A and B more or less say the same thing, and both describe the littoral zone. It almost always features vegetation (think of plants growing out of marshes and near/in the shore of rivers and lakes). It stabilizes the soil by providing a more gradual transition from land to water. For example, an area that only the high tide of the sea reaches will feature some chemical composition of the sea bed, such as more water and salinity, and some of the land further inland.
A eukaryotic cell is much more complex than a prokaryotic cell. Eukaryotic cells usually make up more complex organisms and have organelles such as endoplasmic reticulum, Golgi apparatus, mitochondria, a nucleus, and lysosomes. A prokaryotic cell only has circular chromosomes and is much smaller than a eukaryotic cell. Most single celled organisms are prokaryotes.
