Why are the women considered as a ideal members of a society justify it

VMariaS [17]

Answer:

women bexause...

Explanation:

Throughout history, the central role of women in society has ensured the stability, progress and long-term development of nations. Globally, women comprise 43 percent of the world’s agricultural labor force – rising to 70 percent in some countries. For instance, across Africa, 80 percent of the agricultural production comes from small farmers, most of whom are rural women. It’s widely accepted that agriculture can be the engine of growth and poverty reduction in developing nations. Women, notably mothers, play the largest role in decision-making about family meal planning and diet. And, women self-report more often their initiative in preserving child health and nutrition.

What type of weights shpould you not use if your goal is to build muscle mass

Ymorist [56]

I believe that you shouldn't use low intensity (light weights) if you want to build muscle mass.
These types of weights won't help you much define the muscles you want to have, as opposed to free weights, weight machines, and high intensity (heavy weights) which definitely will. So if your goal is to build muscle mass, avoid light weights.

Jessica's new diet plan contains 3.3 mg of heme iron and 17.5 mg id non heme iron. what us the amount of biologically available

Hitman42 [59]

1.37mg is a total concentration of iron.

Further Explanation:

Iron is a vitally important element that is required for oxygen transport as a component of hemoglobin. Haemoglobin is composed of two components; heme and globin chain. Heme is further composed of two component; iron and porphyrin ring and globin is a protein chain. Heme part of the hemoglobin helps in binding oxygen component whereas globin chain helps in transport because it is soluble in body fluid. When heme group breaks down it release iron and phosphorus in the body fluid. Iron is obtained from dietary source.

The naturally occurring iron is formed in two forms; heme and non heme iron in food that are handled and absorbed by the human cell differently. Heme iron is a kind of iron present in muscle tissue and blood. The source of heme iron is meat, seafood, poultry and fish. It is generally present in the form of animal protein. Non heme protein is a plant as well as animal based iron. They are present in beans, grain, vegetables, fruits, seed, nuts, egg and milk. Heme iron is absorbed more easily in human body than non heme iron.

Biologically available heme can be calculated by the formula given below.

$\text{Biologically available}=\dfrac{\text{dietary intake}\times\text{absorption}}{100}$

The concentration of heme iron can be calculated by,

$\begin{aligned}{\text{Heme iron}}&=\frac{{3.3 \times 15}}{{100}}\\&=0.49{\text{ mg}}\end{aligned}$

Calculate the non heme concentration by,

$\begin{aligned}{\text{Non - heme iron}}&=\frac{{17.5\times5}}{{100}}\\&=0.875{\text{ mg}}\end{aligned}$

Total concentration of iron,

$\begin{aligned}{\text{Total iron}}&=0.49+0.875\\&=1.37{\text{ mg}}\end{aligned}$
