Option A and C are correct.
<h3><u>Explanation:</u></h3>
The DNA is the genetic molecule of a cell in an organism that contains the genetic information stored in forms of genes. The genes are expressed by means of protein synthesis. The genes are formed of particular sequence of nitrogen bases that is called as codon. These codons are transcribed into particular amino acids. This process involves the participation of DNA dependent RNA synthase that produces the mRNA from the portion of DNA by means of transcription. The mRNA that is produced from the DNA is formed of complementary nitrogen bases from the DNA, just exception is that in RNA, thymine is replaced by Uracil. This process is known ad transcription.
The situation would be that, in a sealed tube, there are 3 to 4 nails inside and a certain amount of calcium chloride was added. After three days, there will be no changes to be observed in the first tube since the oxygen is not enough to initiate a change and there is no presence of water. For the second test, the same situation is made but boiling water was filled in the tube. For this, no changes would still be observed since there is no moisture. For the last test, the same situation as the first but it is filled halfway with water. After 3 days, rust would be observed on the nails. In order for rust to happen, there should be water and oxygen. The oxygen in the early atmosphere of the Earth would react with iron present in the oceans thus producing iron ores.

Mammals
just like us humans. have backbone, lungs, and reproduce on land
