<u>Answer:</u>
A recombinant DNA molecule is produced by "genetic recombination laboratory methods".
<u>Explanation:</u>
The genetic recombination laboratory methods like molecular cloning is responsible for rDNA molecules formation. The steps involve pooling of genetic material from number of sources and generate very unique sequences which is not available in the genome.
The another method used for recombinant DNA molecule production is Polymerase chain reaction (PCR). This involves millions to billions of copies of a single DNA sample which allows easy access for scientists to take minute amount of DNA sample and make it to a appropriate large amount, as needed to follow deep analysis.
Here are two examples of how nutrients help to maintain homeostasis in our body:
1. The carbohydrates that we take gives us the energy that we need. It serves as our main source of energy, especially for the brain, to function properly. Having the right and sufficient amounts of carbohydrate intake maintains the normal blood glucose in the body.
2. The intake of sufficient vitamins is necessary for the synthesis of collagen that is important for the structure of the blood vessels, bones and ligaments. Specifically, vitamin D helps in maintaining the homeostasis of calcium in the body. This vitamin can be found in food sources or synthesized by the sun.
