Hello. This question is incomplete. The complete question is:
"What is a characteristic of total body fat? It includes stored fat in body tissue. It includes essential fats harmful for cell function. It can be used to determine a person’s body weight. It can be used to determine body mass percentage.
"
Answer:
It can be used to determine body mass percentage.
Explanation:
Total body fat can be used to determine the percentage of body mass.
Your body fat percentage is simply the percentage of fat your body has. Total body mass includes body fat and lean mass values (muscles, organs, blood, and everything else). A certain amount of fat is essential for the body to perform vital functions. Therefore, a person can never get rid of all the body fat but lower the percentage so that the body becomes shapely and the muscles begin to appear.
The pancreas secretes trypsin and chymotrypsin enzymes which continue breakdown proteins into smaller peptides and some single amino acids. Carboxypeptidase also secreted by the pancreas splits single amino acids from the carboxyl end of proteins.
Bile, which contains a mix salts, is secreted by the liver . Bile salts help to continue digestion of fats by attaching to small fat droplets, preventing them from coalescing into larger droplets, thereby increasing their surface area so that they can be further broken down by lipase enzymes.
Answer:
The immune response is how your body recognizes and defends itself against bacteria, viruses, and substances that appear foreign and harmful.
Information
The immune system protects the body from possibly harmful substances by recognizing and responding to antigens. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. Nonliving substances such as toxins, chemicals, drugs, and foreign particles (such as a splinter) can also be antigens. The immune system recognizes and destroys, or tries to destroy, substances that contain antigens.
Your body's cells have proteins that are antigens. These include a group of antigens called HLA antigens. Your immune system learns to see these antigens as normal and usually does not react against them.
