Suzy is shown a glass of water. She watches as that water is poured into another taller, thinner glass. If Suzy is able to understand that the quantity of water did not change during this process, what stage of development is she likely in according to Piaget's model of cognitive development?

This suggests that Suzy is able to understand conservation. Therefore, she is likely in what Piaget referred to as the Concrete Operational Stage. Suzy is probably between 7-11 years old and is starting to develop logical thought processes.

What are some examples of non covalent interactions in biomolecules and what are their relative strengths?

From strongest to weakest, some examples of non covalent interactions are: ionic interactions, hydrogen bonds, dipole-dipole interactions, and induced dipole-induced dipole interactions.

What is the difference between DNA transcription and translation?

DNA transcription is the process by which DNA is copied to make mRNA, which will carry the information needed to make a protein. Once the mRNA is transported outside the nucleus to the cell ribosome, it can direct translation, which is the process of protein synthesis.
