What are digestive enzymes used for?
The body produces enzymes in the digestive system, including the mouth, stomach, and small intestine. But most of it is work of the pancreas. Digestive enzymes help the body break down carbohydrates, fats and proteins.
Malabsorption syndrome refers to a variety of disorders in which nutrients from food are not properly absorbed in the small intestine. Certain disorders, infections, and surgical procedures can cause malabsorption.

Exposure to the building material asbestos has been linked to certain types of cancers. Asbestos causes mutations in the p53 gene, which controls tumor suppression. Which statement best explains why people with cancer due to asbestos exposure do not pass the mutation on to their offspring?.
Answers
The reason why people with cancer due to asbestos exposure do not transfer (pass) the mutation unto their offspring is because the mutation occurred in somatic cells.
Cancer can be defined as the uncontrolled division of certain somatic cells, which then invade the surrounding tissues and interfere with the normal functioning of the human body.
Over the years, the exposure and inhaling of building material such as asbestos into the lungs has been linked to the cause of certain types of cancers such as mesothelioma. This building material (asbestos) results in the mutation of the p53 gene, which is mainly responsible for controlling tumor suppression in living organisms.
However, people that develop cancer due to an exposure to asbestos, do not transfer (pass) the mutation unto their offspring because the mutation took place in somatic cells rather than in sperm and egg cells.
