The correct answer is letter A. Enzymes assure that digestion occurs within hours instead of days. These chemicals release fast acting agents that digest food and turn it into usable energy within the body. Without these enzymes digestion would occur at a very slow pace and the body will become weak because of the lack of nutrient absorption.
A pedigree is a symbolic diagram that is used to show the presence and presentation of specific alleles in the families of both parents. This is used mostly for genetically controlled diseases and conditions. If a couple is in genetic counseling a pedigree is valuable in helping to determine the risk of that couple having a child that will either present with the condition or be a carrier for the condition. A pedigree is also composed in a way, with shapes and colors, that is an easy to understand visual representation of the inheritance patterns.
Answer:
Because the gene is an inheritance of our ancestors, weight is something you gain or lose depending on how balance your health is. The reason why our weight can't be controlled by the gene is because the gene has different traits coming from each parents(50%) and grandparents(25%), and either parents has different weight, so it will be hard for the gene to capture one specific weight from both sides.
