The three changes of state during which energy is absorbed are:
1. Change from solid to liquid - Melting.
2. Change from liquid to gas - Vaporization
3. Change from solid to gas - Sublimation
All these changes of state require heat energy to break the attractive forces that hold the particles of the molecules together, so that they can move into more disorderly states. For instance, when heat is applied to a solid, the solid absorbs the heat and use it to break the attractive forces that are holding the molecules of the solid together. At a particular temperature, the attractive forces will be completely overcome and the solid framework will collapse, thus leading to the melting of the solid.
Answer:
Phoebus Levene.
Explanation:
Two types of nucleic acids are DNA and RNA. The monomers of mucleic acid contains the pentose sugar, nitrogenous bases and the phosphate group attached with the bases.
Friedrich Miescher was the first scientists who discovered the nucleic acids. He identified the nucleic acids from the bandage that contains the nuclei of white blood cells. The new compounds discovered is known as nucleic acid. But the monomers of the nucleic acids was first explained by Phoebus Levene. Different forms of nucleic acid was also postulated by Phoebus Levene.
Thus, the answer is Phoebus Levene.
Answer:
The Six Kingdoms. When Linnaeus developed his system of classification, there were only two kingdoms, Plants and Animals. But the use of the microscope led to the discovery of new organisms and the identification of differences in cells. Today the system of classification includes six kingdoms.
