The reason for governments to intercede in the market is to insure there is regulation and no black market trading or selling occurring
with this, the government will create an equal opportunity for everyone to enter the market

Hope this helps

The table below shows the radioactive decay of' a 10 kg sample of carbon-14. Create a graph using the data
tatyana61 [14]

C-14 half-life is the time it takes for half of the isotope mass to decay into its daughter form. Line graphs are the best way to represent data about half-lives and the amount of isotope (gr).

<h3>What is Carbon 14?</h3>

Carbon 14, also known as radiocarbon, is a radioactive carbon isotope.

Isotopes are the atoms of the same element -carbon- that vary in neutrons and, hence, in their massic number. They are alternative forms of the same element.

The radioactive C14 nucleus contains 6 protons and 8 neutrons and has a half-life of 5730 years.

The term <u>half-life</u> is a reference. It means that an organism that has been dead for 5730 years has half the C14 amount or concentration than the same organism had when it was alive.

In other words, the half-life is the time it takes for half the mass of this isotope to become its daughter form.

Knowing the half-life of an element is useful to determine the age of the dead matter.

C14 is used in radiocarbon dating techniques or methods to estimate the age of fossils. This is a reliable technique used for dating organic samples that are less than 50,000 years old.

An easy way of representing the change in mass of the isotope through the years is to make a line graph, which is easy to interpret and compare the information.

In this example, our line graph must represent the number of half-lives related to the amount of parent isotope in grams.

The table details the years and the amount of isotope. So, by kowing the half-life of C-14, we can get how many half-lives there are.

5,700 years ---------- 1 half-life

11,400 years--------- X = 2 half-lives ⇒ (5700 x 2) or (11,400/5,700)

17,100 years -------- X = 3 half-lives ⇒ (5700 x 3) or (17,100/5,700)

22,800 years ------ X = 4 half-lives ⇒ (5700 x 4) or (22.800/5,700)

28,500 years ------ X = 5 half-lives ⇒ (5700 x 5) or (28,500/5,700)

34,200 years ------ X = 6 half-lives ⇒ (5700 x 6) or (32,200/5,700)

39,900 years ------ X = 7 half-lives ⇒ (5700 x 7) or (39,900/5,700)

45,600 years ------ X = 8 half-lives ⇒ (5700 x 8) or (45,600/5,700)

51,300 years ------- X = 9 half-lives ⇒ (5700 x 9) or (51,300/5,700)

Now, we can make a new table,

<u>Number of half-lives       Carbon-14 (g) </u>

                0 ..............................10,000

                 1 ...............................5,000

                 2................................2,500

                 3 ................................1,250

                 4 ................................  625

                 5 ................................  312

                 6 ................................  156

                 7 .................................   78

                 8 .................................   39

<u>                  9 .................................   20         </u>

<u />

Finally, we can make the line graph using the data of this new table. You will find it in the attached files.

In conclusion, the best graph you can make is a line graph, and if they ask you to graph the number of half-lives and give you the number of years, you can just make the conversion using the half-life of the isotope.

What blood vessel delivers oxygenated blood to the heart structure that separates the left and right ventricles?
xenn [34]

Answer:

The left side of the heart receives oxygenated blood from the pulmonary vein and pumps it into the aorta, while the right side of the heart receives deoxygenated blood from the vena cava and pumps it into the pulmonary vein. The pulmonary vein and aorta also have valves connecting them to their respective ventricle.

Which class of molecules functions as chemical signals?
omeli [17]
A hormone is a molecule that functions as a chemical signal. A hormone is a chemical released by a cell or a gland in one part of the body that sends out messages that affect cells in other parts of the organism. Endocrine hormone molecules are secreted (released) directly into the bloodstream. !

The rate of kidney filtrate formation would normally be dependent upon all of the following factors except __________.
Anton [14]

Answer: blood calcium level

Explanation:

There are several factors affecting the rate of kidney filtrate formation including filtration membrane integrity

, systemic blood pressure, and renal artery/arteriole diameters.

Filtration membrane integrity

: It regulates the filtration of small fitrates and large filtrates. It is very important to handle the osmotic pressure of salts, if it will get damage the filtration will not take place properly.

Systemic blood pressure: systemic blood pressure is very important factor as it affects the Glomerular Filtration Rate (GFR). Low blood pressure or volume due to dehydration can result in decreased GFR.

Renal artery/arteriole diameters: The filtrate move through the renal artery and if it's diameter will increase or decrease it will affect the movement of filtrate. if diameter will decrease it can block the renal artery and can cause a huge damage.

Blood calcium level do not have any role in the kidney filterate formation or renal regulation.

Hence, the correct option is blood calcium level.
