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,

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

An infant was born with facial nerve paralysis that occurred with delivery. As the infant ages, it becomes apparent that the fac

Ratling [72]

Answer:

lose their ability to proliferate once development of the nervous system is complete

Explanation:

The nervous system is a very essential system in a person's body. It starts developing from the first trimester of pregnancy and becomes fully developed during the woman's third trimester of pregnancy until the fetus is born. Thus, anything that happens during or after the woman's pregnancy may affect the infant's brain development.

In the situation above, the baby was born with facial nerve paralysis. This is a condition which causes some problems to the newborn, such as uncontrollable facial movements. It could be a result of trauma to the facial nerve. The trauma can happen before or after birth.

Remember that once the nervous system is complete, it cannot repair or proliferate anymore. This makes the cells in the nervous system different from all the other cells in the human body. In the case above, the infant permanently lost his ability to have a functioning facial nerve.

Thus, this explains the answer.
