Nitrogen is very important for plants growth. Nitrogen fixation is the process by which atmospheric nitrogen is assimilated into organic compounds especially by microbes. Nitrogen fixation can be carried out by bacteria and lighting. The vast amount of energy in lightening decompose nitrogen molecules and enables the nitrogen atoms to combine with oxygen in the air forming nitrogen oxides. These oxides dissolve in the rain to form nitrates which are carried into the soil. The percentage of nitrogen fixed by this method is between 5%- 8% of all nitrogen fixed.

What are two types of evidence that suggests that evolution has occurred

sashaice [31]

There is evidence that evolution occurred, but nothing is proved for sure. I'm sure you can find the information if you search it on the internet. Sorry, this probably won't be helpful for your question, but please don't hate. I just wanted to tell you that you might want to think about the possibility that there wasn't a big bang, and everything spontaneously appeared, or that everything evolved from a single bacteria or whatever, or that the earth is billions of years old. If you look into it, lots of that evidence isn't even lined up correctly. I believe that there is a creator, who carefully designed everything with love. I know it sounds cheesy, but this creator, or designer who made all of us, is the reason we even celebrate Christmas. Anyway, thanks for reading this, God bless.

Which value is being measured in the columns labeled fraction remaining and percentage remaining

ahrayia [7]

Question:

Which value is being measured in the columns labeled "Fraction remaining” and "Percentage remaining”?

years of decay
quantity of energy
number of stable atoms
amount of material that has not decayed

Answer:

"Amount of material that has not decayed" being measured in the columns labelled "Fraction remaining” and "Percentage remaining”

Explanation:

The table shown below having explains about the half life , the amount of sample in both fraction and percentage. The first column named half life elapsed tells us the the number of half life that that is completed. Half life is the time taken for an element to reduce or decay into half of its initial amount.

The fraction remaining column gives the amount of sample that is left behind after the half life particular number of half life has completed. similarly the percentage remaining column gives the amount of sample in percentage. For example, the 5th row tells us that after 4 half life is over $\frac{1}{16} th$ of the sample remained. In percentage it is 6.25%
