Answer:
Air is a bad conductor because, to conduct heat current molecules should absorb heat and transmit it to neighbor by vibrating. So , "If air were a good conductor of heat" then soup will not stay hot for longer because this time convection+conduction will both help to transfer heat away from soup.
Explanation:
Answer: Unicellular and multi cellular organisms have some similarities and differences between them. The similarities between the two are listed below:
1.One big similarity between unicellular and multi cellular organisms is that the two of them are made up of cells.
2. The two organisms have similar genetic codes; both type of cells has DNA as hereditary material. The genetic code is universal and DNA sequence from a unicellular organism can be reproduced by a multi cellular organism and vice versa.
3. Both unicellular and multi cellular organisms have the same type of cell membrane. The cell membrane are made from phospholipids and they also incorporate different types of proteins.
4. Both organisms also have ribosomes in their cells. The ribosomes are responsible for the synthesis of proteins. Both cells synthesis proteins.
5. Both type of organisms have to obtain energy and nutrients to sustain their growth and energy.
