The body's nonspecific defiance against invading pathogens is known as innate immunity and includes the following:
mechanical barriers and surface secretions
1. The intact skin and mucous membranes of the body. These provide a high degree of protection against pathogens.
2. The sebaceous secretions and sweat of the skin contain bactericidal and fungicidal fatty acids that can kill bacteria and fungi.
3. Normal bacterial flora of the skin may produce various antimicrobial substances such as bacteriocines and acids.
Humoral defence mechanisms
1. Lysozyme. This is an enzyme found in most tissue fluids apart from cerebrospinal fluid, urine, and sweat. It can kill bacteria.
2. Interferon. Inhibits viruses from replicating
3. Complement. This is a heat labile serum that can destroy gram-negative bacteria.
Answer:
447 calories
Explanation:
1 gram of fat is 9 calories
1 gram of carbohydrate is 4 calories
1 gram of protein is 4 calories
In one granola bar:
5 grams of fat = 5 x 9 = 45 calories
19 gram of carbohydrates = 19 x 4 = 76 calories
7 grams of protein = 7 x 4 = 28 calories
for a total of 45 + 76 + 28 = 149 calories
If Carter ate 3 granola bars then 149 x 3 = 447 calories
The natural water sample contains only one type of bacteria.
Low-density lipoproteins (LDL) are the principal transport vehicle for cholesterol in the blood.
The body needs cholesterol, a waxy, fatty molecule, in the proper proportions for overall health. High blood cholesterol is a disorder that can result from unfavorable cholesterol levels. Low-density lipoprotein (LDL), also known as "bad" cholesterol, is the type of lipoprotein that carries cholesterol in your blood.
Cholesterol is primarily brought on by consuming fatty foods, failing to exercise regularly, being overweight, smoking, and using alcohol. Moreover, it can run in families. By consuming a healthy diet and increasing your physical activity, you can lower your cholesterol. Some folks also require medication. The majority of the cholesterol in your body is LDL (low-density lipoprotein), also referred to as "bad" cholesterol. Your risk of heart disease and stroke increases if your LDL cholesterol levels are high.
