The answer is A, it's made out of buried plants and animals
They create a different substance because on the periodic table each substance has a certain amount of protons and if you add or take away protons and/or electrons it will create a different substance. For Example Nickel has 28 protons but if you add 2 more you get zinc and that has 30 protons. Another Example is
what if you have Titanium which has 22 protons and take away 2 you get Calcium which has 20 protons.

D) the last one bc water goes in and make electrical power
Poop. I don't really know what you are asking but the excretory system removes the stuff from our stomach that we cant use or stuff that already has all of the nutrients that we need removed. Hope this helps
With this information I don’t fully understand the question but broadly speaking any sequence that would not made transcribed into the correct RNA from the DNA will be
mutant.
Example is the first normal DNA is read 5’ - GGT 3’ and the RNA will be 3’CCA’ 5’ as it is COMPLEMENTARY. (Important keyword with this)
If the assignment wants you to have a silent mutation that Change the RNA to something that is not complementary to the DNA but will still produce that same protein as the example above. If you need to make a new protein change the rna so the codon will make a different protein from the above sequence
