A. A. A stress test can be used to test for heart disease. Stress tests are tests performed by a doctor and/or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle).
The four types of organic compounds are carbohydrates, lipids, proteins and nucleic acids. Organic molecules contain the elements carbon and hydrogen, and they are found and made in living things. Keep Learning.
Organic chemists divide all the organic compounds into two groups as aliphatic and aromatic compounds. This separation is based on the way carbon atoms are arranged in the molecule. Aliphatic. Aliphatic compounds in organic chemistry are the non aromatic compounds.They can be either cyclic or acyclic.rganic molecules are molecules consist of carbons. Organic molecules are the most abundant molecule in living things on this planet. Therefore, organic molecules are associated with nearly every aspect of our lives. Therefore, a separate subject as organic chemistry has evolved to learn about these compounds.
