Despite her retirement, her dietary practices remain essentially the same, except that she buys meats from the grocery store and makes her own sandwiches now. Karen rarely ever drinks plain water, herbal tea, juice, or milk-black coffee and red wine are her only sources of hydration. For many years, Karen has battled kidney stones, high blood pressure, headaches, and chronic fatigue.
Karen was told by her doctor that increasing her magnesium intake might help with the weakness she has been feeling. Which of the following meals has the highest levels of magnesium?

a. turkey with a spinach salad and a glass of soy milk
b. beef burrito with cheddar cheese, tomatoes, and lettuce
c. steak with mash potatoes and a glass of water

Option A

turkey with a spinach salad and a glass of soy milk meals has the highest levels of magnesium

<h3><u>Explanation:</u></h3>

Magnesium is a mineral that our bodies rely on to sense fit, fit and full of energy. Magnesium is also needed for “development of bones, muscle compressions, and blood pressure control”.  It is also believed to perform a task in sleep by promoting our sleep quality.

In ordinary, men need about 400mg of magnesium per day and women require about 300mg per day. The highest item comprising magnesium which is Spinach, steamed, blanched, drained, without salt. 79 mg of magnesium per 100g, from Spinach. Seafood turkey has good magnesium content.

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 <u>two components; heme and globin chain</u>. 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 <u>heme group breaks down it release iron</u> 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 <u>iron present in muscle tissue and blood.</u> 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}

1) Neurons propagate signals in the form of action potentials that are mediated by:
Mama L [17]
1. The correct answer is a.
Neurons communicate using action potentials, that travel down neurons using an electrochemical cascade. These action potentials are mediated by changes in the polarity of the cell membrane. At the beginning of the action potential, the Na+ channels open and this causes an influx of Na+ into the nerve cell, triggering, in turn, the depolarization of the membrane.

2. The correct answer is b.
The Krebs cycle (also known as the citric acid cycle) is a process involved in cellular respiration. The Krebs cycle happens in the mitochondria and involves the transformation of Acetyl coA to molecules, that will then be used to create ATP (the energy molecule). Acetyl coA goes through several chemical transformations and the energy released is transferred to NAD and FAD. In a process before the Krebs cycle, Pyruvate (produced by glycolysis) forms the acetyl coA. Therefore, pyruvate does not intervene in the Krebs cycle.

3. The correct answer is b.
The neuromuscular junction is a chemical synapse connecting a motor neuron and a muscle fiber. The signal transmitted from the motor neuron to the muscle fiber triggers the muscle contraction. The process is mediated partly through ion channel linked receptors. When acetylcholine (the ligand) binds to the receptor, the ion channel part of the receptor opens and this produces an influx of ions intracellularly.
 
4. The correct answer is c.
Cystic fibrosis is a inherited disorder that affects mostly the lungs, but also other organs of the body, such as the liver and the pancreas. It is caused by a mutation in the CTFR gene. This gene encodes a protein that is a chloride ion channel and is responsible for the movement of water in and out of the cells. The mutations in this gene result in a disruption of this ion channel, causing a change in the consistency of the mucus and sweat produced by the organism.

5. The correct answer is d.
The CTFR protein (the product of the CTFR gene) is a chloride ion channel regulated by cAMP. This ion channel is activated by phosphorylation, caused by cAMP - dependent protein kinase (PKA). PKA needs to bind two cAMP in order to be activated and able to phosphorylate other proteins.

A measure can be considered valid until the measure is reliable. Health-o meter scale is a reliable, accurate,  and repeatable medical scale which is used to measure the weight of the people in the hospital or clinic.

This machine or scale is also used in the gym where the people want to measure the weight more actively.

Hence, option D is the most reliable and relevant source for the interrater reliability.
