I. Blood is pumped from the left ventricle through the aortic valve and into the aorta.

jeyben [28]

Answer:

Health is a state of physical, mental and social well-being, not just the absence of disease or infirmity. Good health helps us live a full life.

Explanation:

"Healthy living is about respecting my mind, respecting my body and remembering that what goes into my body can affect my mind and everything’s connected." When our physical health is suffering, it’s easy to see: a broken leg, a cut or a bruise, a limp. When our mental health is suffering it can be more difficult to spot.!!

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,

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

What is the ancer to NATO and the Warsaw Pact were two competing alliances during which time period? Test

miv72 [106K]

Answer: NATO and the Warsaw Pact were two competing alliances during COLD WAR time period.

Explanation:

Cold war was an era that started immediately after the second world war.This was to be a long lasting and continuing confrontation between the Soviet Union and the United States, lasting from 1945 to 1989. It was called the Cold War because neither the Soviet Union nor the United States officially declared war on each other.

The two major cold war alliances were the NATO (North Atlantic Treaty Organisation) and the Warsaw Pact. The countries that make up the NATO includes Britain, France, the United States, Canada, and eight other western European countries while Warsaw pact was created by Soviet Union.

For years the both alliances never engaged in military war but developed strategic policies aimed at the containment of each other in Europe while working and fighting for influence within the wider Cold War on the international stage. I hope this helps, thanks!
