Question

Which of the following are not properties of carbon?

.It's very cohesive and adhesive.
.It can form polymers like carbohydrates, lipids, proteins, and nucleic acids.
.It can regulate temperature.
.Decomposition of molecules can occur readily, releasing needed energy.

Answer 1

Carbon can form polymers and has several unique properties, but it does not directly regulate temperature.

Step-by-step explanation:

Carbon is a key element in organic compounds and has several unique properties. One of these properties is its ability to form stable covalent bonds with other carbon atoms and atoms of other elements, allowing the formation of complex molecules such as carbohydrates, lipids, proteins, and nucleic acids. Another property is carbon's role in regulating temperature; however, this statement is not accurate. Carbon itself does not directly regulate temperature. Lastly, decomposition of molecules can release energy, but this is a general property of many organic compounds, not specific to carbon.

Answer 2

Option C, It can regulate temperature

Step-by-step explanation:

Carbon atom is able to form bonds with other carbon atoms or atoms of hydrogen , oxygen , nitrogen , phosphorus etc. A carbon forms a diamond/graphite when it joins cohesively while they form molecules like hydrocarbons, CO2 etc, when it joins adhesively with other than carbon atoms. Thus Option A is incorrect

Since carbon combines with other chemical atoms to form polymers, lipids , proteins etc, as they are adhesive to other than carbon atoms. Option B is also incorrect.

Option C, is a physical phenomena in which carbon compounds do not allow heat to escape from earth and in this way it regulate the temperature of earth. This is not an internal property of carbon and hence option C is correct.

Option D is incorrect as carbon can be easily decomposed along with production of energy by decomposers or by burning the fuels containing carbon.
