<span>You can express the gene of one organism in another one because the translation from DNA to protein is the same in all organisms. For the same nucleotide sequence, you will get the same amino acid sequence in your protein. There are some epigenetic differences between eukaryotes and prokaryotes (this means, the DNA is modified differently in the organisms). But you can avoid that.</span>
Metals such as iron have low specific heat. It doesn't take much energy to raise their temperature. That's why a metal spoon heats up quickly when placed in a cup of hot coffee. Sand also has a relatively low specific heat.
