Answer:
Polypeptide
Explanation:
Amino acids are the building block and simplest unit of protein molecules. The structural composition of each amino acids is made up of an amine group (-NH2), a carboxylic acid group (-COOH), a hydrogen atom (H) and a R side chain that differentiates every amino acid from one another.
In a reaction process called condensation, amino acids are chemically joined together via the amine group of one and the carboxylic group of another. This process releases water molecule (H20) to form a bond called PEPTIDE bond between the amino acids. Several amino acids in their 100’s or 1000’s that are chemically joined this way forms a POLYPEPTIDE chain, which in turn forms the protein molecule.
Answer:
Make sure everyone meets criteria.
Not taking supplements( As some may contain Vit D)
No tanning beds
make sure no one has a hypoactive response to vitamin d through whatever way. Injection, capsule, spray.

These are some of the main things to look out for
Crystalline silica is a natural compound in the earth's crust and is a basic component of sand and granite. Silicosis is an incurable disease of the lungs caused by breathing crystalline silica dust. This dust can cause scar tissue to form in the lungs.
All plants are autotrophic.
Autotrophic means he doesn't need another living thing to live(for eating) but that he makes his own food (photosynthesis). (auto means itself).
Heterotrophic means he needs others to keep on living. Like animals. All animals need to eat and can't make their own food with only sunlight, CO2 and water. They need food, which may be plants or other animals. That depends on the animal.
