You are trying to produce cDNA starting from mRNA in skeletal muscle cells. You add the following components to a tube and let the reaction proceed: skeletal muscle mRNA, free nucleotides, and DNA polymerase. After inspecting the products of the reaction, you do not find any cDNA molecules at all. What is the most likely explanation for this result?

unicellular organisms, like bacteria, are able to perform all life functions within one single cell. multicellular organisms need many different types of cells to carry out the same life processes. each of these special types of cells has a different structure that it perform a specific function.

rising temperatures because when water vapor in the air is cooled, it condenses. it turns back into a liquid and attaches to dust particles in the air. these very small water droplets group together to form clouds

this would be called the responsiveness
