Answer:
DNA carries all of the information for your physical characteristics, which are essentially determined by proteins. So, DNA contains the instructions for making a protein. In DNA, each protein is encoded by a gene (a specific sequence of DNA nucleotides that specify how a single protein is to be made).
Explanation:
The answer is B, the sugar moves through the phloem.
Plant has 2 main vessels, xylem and phloem. Xylem is used to move water and mineral ions from the root where it absorbed to the leaves, meanwhile the phloem moves the sugar or food from the region of production, which is usually the leaves, to the places that needed or used for storage.
So since the leaves produces sugar, and peas needed the sugar, so we know that the answer should be phloem.
Meanwhile, stomata is used to release oxygen and water vapor, which are the by products of photosynthesis, and vacuoles are just mainly water substances that exist in most plant cells.

The inheritance of Becker and Duchenne dystrophies are linked to the X chromosome.
Explanation:
Duchenne and Becker muscular dystrophies (DMD and BMD, respectively) are neuromuscular diseases characterized by progressive muscle atrophy and weakness, as a consequence of the degeneration of skeletal, smooth and cardiac muscles. Both muscular dystrophies are caused by mutations in the DMD gene, located on the X chromosome. This is the largest known human gene and it encodes a protein called dystrophin, which is expressed in muscle cells. The mutations responsible for DMD lead to a total absence of dystrophin, while those underlying DMB lead to an abnormal quantity and / or quality of the protein. In both cases it is common to find deletions of the gene.
