Answer:

Microorganisms and certain plant roots in the soil

Explanation:

"Plants get the nitrogen that they need from the soil, where it's already been fixed by bacteria and archaea. Bacteria and archaea in the soil and in the roots of some plants have the ability to convert molecular nitrogen from the air (N2) to ammonia (NH3)... Such organisms are called "diazotrophs". From here, various microorganisms convert ammonia to other nitrogen compounds that are easier for plants to use. In this way, plants get their nitrogen indirectly from the air via microorganisms in the soil and in certain plant roots."

I hope this helps...

Learning Task 2. Find the equation of the line . Write in slope intercept form

Damm [24]

Answer:

(1) m = -5, b= 1

$\frac{x}{a} + \frac{y}{b} = 1$

put b=1 (given)

$\frac{x}{a} + \frac{y}{1} = 1$ => y = -x/a + 1

-1/a is representing slope here which is given as -5

-1/a = -5 => a = 1/5

slope intercept form

y = mx +b

y = -5x + 1

standard form

5x +y = 1

(2). (1, -2), (3, 3)

m = 5/2

slope intercept form

y - 3 = 5/2*( x -3)

y = 5x/2 -9/2

standard form

5x -2y = 9

(3). (-2, 0) and (0,5)

m = 5/2

slope intercept form

y - 0 = 5/2 ( x+2)

y = 5x/2 + 5

standard form

5x -2y = -10

(4). a = 2, b = -7

$\frac{x}{2} + \frac{y}{-7} =1$

slope intercept form

y = 7x/2 -7

standard form

7x -2y =14

(5). m=2,(3,-1)

slope intercept form

y +1 = 2(x -3)

y = 2x -7

standard form

2x -y = 7

Pay for the right to use it.<br> 30.<br> How can Celera make a profit off of sequencing our DNA?

Shtirlitz [24]

Answer:

Charge us

Sell the info

Explanation:

They can first charge individuals to use the services. For example, similar to 23andme or Ancestry, who provide a service of telling you interesting things related to your health or ethnicity.

They could also sell that data to pharmaceutical companies or other research groups who can use the DNA information for research. The more samples of DNA we have sequenced, the more information scientists have to work with and design drugs and more.
