Industry would have unlimited ability to produce chemicals for use as pesticides, additives, etc without being required to measure their effects on people or their accumulation in water or soils and their impact on the environment, their toxicity, and potential exposure hazard
Waste water would be monitored, but there would be no limits or benchmarks for the levels of contaminants in the water
Automobile manufacturers would not be required to adhere to achieve a specific benchmark for noxious gas output, and cars would not be monitored for their output over time. It is debatable if gas mileage would be a consideration, as the only motivator for manufacturers to increase fuel economy would be the price of fuel and consumer willingness to bear the burden of fuel costs

1) TARGET HEART RATE

Veseljchak [2.6K]

Answer:

A 17 year old with a resting heart rate of 62 bpm has a maximum hearth rate of 203 bpm, a hearth rate reserve of 141 bpm and target hearth rate between 161 and 182 bpm

Explanation:

Target heart rate is a measure used to calculate the range of heart rate that should be maintained during intense exercise.

Knowing a person's age and resting heart rate (RHR), a target heart rate calculation can be made from the maximum heart rate (MHR) and the hearth rate reserve (HRR)

Data:

- Age: 17 years old

- RHR: 68 bpm

The maximum heart rate is calculated by subtracting age from a constant value of 220, so:

MHR = 220 - age
MHR = 220 - 17
MHR = 203 bpm

HRR is calculated by subtracting the resting heart rate (RHR) from the MHR value:

HRR = MHR - RHR
HRR = 203 - 62
HRR = 141 bpm

THR is obtained by multiplying the HRR by 0.7 and 0.85, to obtain the range of heart rate in which the exercise can be performed.

THR lower limit = (HRR x 0.7) + RHR Lower THR = (141 x 0.7) + 62 = 160.7 ≈ 161 bpm
THR top limit = (HRR x 0.85) + RHR THR top = (141 x 0.85) + 62 = 181,85 ≈ 182 bpm

For the 17-year-old, the ideal target heart rate for an intense exercise is between the values of 161 and 182 bpm.

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,

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