What are the similarities and differences between replication and transcription?
What are the similarities and differences between replication and transcription? Both DNA replication and Transcription involve the generation of a new copy of the DNA in a cell. DNA transcription is involved in replicating the DNA into RNA, while the DNA replication makes another copy of DNA. Both the process is involved in the production […]
What is the movement of the surface of the water?
What is the movement of the surface of the water? Surface movement includes rivers, streams, creeks, lakes, ponds, and human-made “flood” control. All surface water is trying to reach sea level due to gravity. As water flows in channels, the streambed and banks of the channel will resist the flow of water. Who has the […]
Does salt and sugar affect water evaporation?
Does salt and sugar affect water evaporation? You are right in that the salt water and sugar water should have evaporated more slowly. The reason for this can be explained with some advanced chemistry, but I’ll try to explain in simpler terms so your son can understand it. Does salt water or pure water evaporate […]

What are the two types of reflection?
What are the two types of reflection? The reflection of light can be roughly categorized into two types of reflection. Specular reflection is defined as light reflected from a smooth surface at a definite angle, whereas diffuse reflection is produced by rough surfaces that tend to reflect light in all directions (as illustrated in Figure […]
What is heating curve?
What is heating curve? A heating curve graphically represents the phase transitions that a substance undergoes as heat is added to it. The plateaus on the curve mark the phase changes. The temperature remains constant during these phase transitions. Which phase is the easiest to heat? Solid Why does the entropy increase dramatically at the […]
