Which of these elements is not likely to be found in an organic compound?
A. carbon
B. hydrogen
C. nitrogen
D. potassium

Answer:

D. potassium

Explanation:

Potassium is not found in an organic compound. Therefore, option D is correct.

Any of a vast group of chemical compounds known as organic compounds contain one or more carbon atoms that are covalently connected to atoms of other elements, most frequently hydrogen, oxygen, or nitrogen.

The building blocks of life's components, such as carbohydrates, fats (lipids), proteins, and nucleic acids, are examples of organic substances. Petroleum and natural gas, which make up the majority of fossil fuels, are also organic molecules.

High molecular weights and complicated structures are features of organic molecules. These are usually insoluble in water but soluble in organic solvents. Potassium is not found in an organic compound. Therefore, option D is correct.

Anthropologists have been studying the role of soybean curd andrelated products in the culture of Hong Kong. The researchers interviewpeople about how frequently they eat soybean products, where they eatthem (at home or in restaurants), and during what time of day they eatthem. The researchers also ask people about how they preparesoybean products, where they obtain soybean products, and any beliefsthey might have about soybean products (such as their nutritionalvalue). The data are used to assess the role of soybean products in theculture. The researchers are also considering how their findings relateto global soybean consumption patterns.

The gene for nose shape is found on the X chromosome. Round nose is dominant to pointed nose. Human individuals with XXY (an additional X chromosome) are designated male. Individuals with XO (only one X chromosome) are designated female. Identify the possible nondisjunction events (rare mistakes during meiosis) that could explain the phenotype of the offspring. An XY parent with a round nose and a XX parent with a round nose have an offspring with Klinefelter Syndrome (genotype XXY) with a pointed nose.
