This field is a subcategory of biology and heredity which is responsible for unearthing and delving the anatomy and physiology of the genes. </span>This field helps us to understand and find evidence in the compounds, substances and elements found and synthesized in our genes and what contains in our nucleic acides –RNA and DNA –framework of our chromosomes. <span>And also the origin and history of how genes came to be. These are codes and like-signals that makes us who we are in a macro-perspective.<span> </span></span>
The best explanation for the process of transpiration in plants is option A. It is the evaporation of water from leaf stomata, which helps in xylem transport. This evaporation of water in the leaves is released to the atmosphere as a vapor. A process called guttation occurs during transpiration wherein the water loss is in a form of liquid from the stem or leaf of the plant.
