Answer:

the answer is that the first pot will succeed

Explanation:

the first pot that contains soil is the one that has loamy soil and when loamy soil contains seed it will succeed. the second pot contains clay because clay is not a soil for planting so is sandy soil they are not for planting.

loamy soil is the best soil for planting.

If Pepsin and Trypsin had to function together, which PH would produce the highest activity? How is this answer found?
san4es73 [151]
The proper environments for Pepsin are acidic, particularly those with a pH of 1.5 to 2. Optimal operating pH for Trypsins is of about 8. It seems that the highest level of activity for the two if they were in the same environment would have to be midway between their optimum range - about pH 5.

Which gene determines what letter is used to represent a pair of traits?
Alex

Answer:

The dominant gene determines what letter is used to represent a pair of letters.

Explanation:

Example: If brown eyes are dominant (B) and blue eyes are recessive (b) then...

BB means: Brown

Bb: still means brown because there is still a dominant gene

bB: still means brown because there is still a dominant gene

bb: means blue, no dominant gene

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.
