In an experiment, you are only allowed to test for one variable at a time. This means that everything else must be the same or constant for only the one variable to be tested for. If say you were testing if plants grow better with more or less water, you need to keep everything else the same.
Answer:
Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.
Explanation:
The question is asking to state the substance that come from the outside in the process of photosynthesis, base on my research and further investigation, I would say that its the heat or light energy. I hope you are satisfied with my answer and feel free to ask for more

Answer:
An amino acid has a common skeleton structure; an alpha carbon joined to 4 groups in its four covalent bonds. The groups are a Hydrogen (-H), a Carbonyl (-COOH), an Amino group (-NH3), and a side chain.
The side chains are variable across all amino acids which is the basis for their identification and naming. The side groups have different properties, therefore, giving different amino acid different structures and properties. These properties help in the folding of polypeptide chains into functional protein structures. This is due to their various interactions between the different amino acids that help proteins form structures like disulfide bridges, beta-sheets and alpha-helices.
