Correct answer choice is:

A.) First line of defense

Explanation:

The immune system can be divided into three basic lines of defense against pathogenic infection. The first line of defense (or exterior defense mode) involves physical and chemical restraints that are perpetually willing and equipped to protect the body from germs. These contain your skin, cracks, excretion, cilia, belly acid, urine flow, 'friendly' bacteria and white blood cells known as neutrophils.

Answer:

1.Your body weight is simply your body's total mass. Body composition is what your weight is made of—muscle, bone, water, and fat.

2.14-20% is considered athletic. 21-24% is considered fit. 25-31% is considered acceptable. 32% or more is considered obese.

3.Body mass index (BMI) is a measure of body fat based on height and weight that applies to adult men and women.

4. 45–65 percent carbohydrates. 10–30 percent protein. 20–35 percent fat.

5.A slow metabolism burns fewer calories, which means more get stored as fat in the body; that's why some people have difficulty losing weight by just cutting calories. A fast metabolism burns calories at a quicker rate, which explains why some people can eat a lot and not gain extra pounds.

6.Protein-rich foods, such as meat, fish, eggs, dairy, legumes, nuts and seeds, could help increase your metabolism for a few hours.

Capsaicin, a chemical found in chili peppers, may boost your metabolism by increasing the number of calories and fat you burn.

The combination of caffeine and catechins found in tea may help your body burn slightly more calories and fat each day
