Answer:
Solution : Combustion of Liquefied Petroleum Gas (LPG) is a chemical change. Because it is an irreversible reaction and new products, carbon dioxide and water vapour are formed and lot of heat is also produced during the reaction.
Answer:
Here’s one possible answer:
Pros
Simple images make the process easy to understand.
The model accurately shows that protein synthesis has distinct stages.
Cons
The model doesn’t accurately show nucleotides in DNA and RNA.
The model doesn’t differentiate between the locations of processes. It fails to show which processes occur in the nucleus and which occur on the ribosome.
