1. The right answer is all of the above.

Most of the human body is water. The cells present in the body have between 65% and 90% of their weight in water. Therefore it is not surprising that the most present element en masse in the human body is oxygen. Carbon, the basic element of organic cells also comes in second place. 98.5% of the mass of the human body is represented by only six elements: oxygen, carbon, hydrogen, nitrogen, calcium, phosphorus (those form the different tissues and organs).

2. The right answer is Does not take into account where your weight comes from (fat vs. muscle).

Weight and height monitoring is particularly important in the early years because of the extraordinarily rapid growth of the child during this period of life.

These curves are used to detect early abnormalities of growth revealed by a weight and / or size that is insufficient or too high in relation to age. To detect the risk of obesity of the child at an early stage, the corpulence curves (or BMI: Body Mass Index) found in the health record have also been used for some years.

3. The right answer is hydrostatic weighing .

Hydrostatic weighing is a method used to determine the density of solids and liquids. It is based on the buoyancy of Archimedes.

Hydrostatic weighing is a procedure that consists in determining the mass of an object, or displacement, by calculating the volume of displaced water, thanks on the one hand to the reading of drafts, and on the other hand to Hydrostatic curves or tables determined by the manufacturer, taking into account the density of a water sample

4. The right answer is all of them.

Lean mass is a complex compartment. It is the most important compartment physiologically. It accounts for 70 to 90% of body weight, and is made up of bones, muscles, organs, skin and body fluids. The basic metabolism of the human being depends essentially on the lean mass.

5. The right answer is True

Adipose tissue, or body fat, is composed of fat cells.

In men, it represents approximately 15% of the total weight  (in women, 25%.)

* In men, adipose tissue give an android shape, that is to say located on the upper part of the body: arms, chest, stomach, shoulders.

* In women, it covers the hips, thighs, belly and buttocks. It gives a gynoid shape.

6. The right answer is BMI.

One study analyzed all-cause deaths and found that a body mass index (BMI) between 20 and 24.9 is associated with the lowest risk of death for healthy non-smoking adults.

The results of the BIA in cardiology were inconclusive. Indeed, it is very variable from one individual to another and varies according to many factors such as breathing, electrode position or perspiration.

7. The right answer is True.

Impedancemetry, or bioimpedance, is the measure of the resistance of biological tissues by sending a sinusoidal current of low intensity (of the order of milliampere) and high frequency (10-100 kHz) through electrodes. By applying a voltage across the electrodes, it is possible to measure an impedance through Ohm's law. There is a risk of error, depending on dehydration ...

8. The right answer is False.

The method of the cutées is validated to appreciate the adiposity (% MG) at the sportsmen, in particular in the categories of weight, and for the longitudinal follow-up of the athletes.

Ideally the measurements should be made by the same operator. Measure of the folds always on the right hemi-body, by convention (for left-handed and right-handed).

9. The right answer is True.

The body mass index (BMI) has differentiated between fat and muscle, and many experts recommend instead to rely on the percentage of body fat for risk loss, especially cardiovascular, associated with an excess of weight.

Epidemiologically, over a very large population, the calculation of BMI - simple, fast and inexpensive

10. The right answer is False.

There are different measurements that can be taken in the human body, and those vary according to men and women, voice some examples: The neck, the chest, the waist, the buttocks, the shoulder width, the lengths arms, wrist circumference, hip circumference ...

These measures become less reliable when the person is too fat or too skinny.

be confident on yourself. ignore such fools and move on ; )

if you think your dog may have been exposed to a toxin, the best thing to do is to check the label of the item you think your pet ingested. read the information about toxicity. often, but not always, the information on packaging regarding children is relevant to dogs and some manufacturers even discuss dog toxicity. if there is an 800 number on the package – call them! it’s also recommended that you call your veterinarian to confirm the recommendations. if you go to your veterinarian, take all packaging and any information you have on the product.
