On a breezy, sunny day where you are sweating profusely, you sit down on a hot park bench. What type(s) of heat exchange is/are

allsm [11]

Answer:

The type of heat exchange that is occurring are as follows: convective, radioactive, evaporative, and conductive.

Explanation:

In convective heat exchange it is due to the fact that the day is windy. This type of exchange is classified as heat loss through the movement of air molecules in contact with the skin. In the radioactive heat exchange it is by UV waves that come from the sun, which transfer heat to the person. The heat exchange by evaporation occurs through the sweating process, thanks to the wind that would be cooling the person. And finally, in conductive heat exchange it refers to the fact that the person is losing heat through physical contact with the park bench.

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,

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

HPV infections, for instance, cause the virus' DNA to combine with the host's DNA, disrupting the normal function of cells. Other viruses, such as human immunodeficiency virus (HIV) and hepatitis C virus (HCV), may increase a person's risk of developing cancer by affecting the body's immune system
