They help convert nitrogen to nitrate which is usable by living beings. (Living beings can't use regular nitrogen)

Bacteria is important to the nitrogen cycle because it breaks nitrogen down that is in the soil into a more simpler form that plants can use.

If bacteria didn't, plants wouldn't be able to intake the nitrogen and do photosynthesis, so we wouldn't get oxygen.

Komok [63]

Answer:

c

Explanation:

Random distribution of the Isopods should be 50/50 in A and B.

Chi-square = \frac{(O - E)^2}{E} where O = observed frequency and E = expected frequency

Chamber         O                    E             Chi-square

  A                   18                   10             \frac{(18 - 10)^2}{10} = 6.4

  B                    2                    10             \frac{(2 - 10)^2}{10} = 6.4

<em>Total Chi-square </em>= 6.4 + 6.4 = 12.8

<em>Degree of freedom</em> = 2 - 1 = 1

<em>Tabulated Chi-square</em> (α = 0.05) = 3.8415

The calculated Chi-square exceeds the critical value, hence, it is significant and not due to random.

<em>The correct option is </em><em>c</em><em>.</em>

The ballistic method of developing flexibility is the safest form of stretching. please select the best answer from the choices
Veseljchak [2.6K]

Answer;

The above statement is false.

The ballistic method of developing flexibility is not the safest form of stretching.

Explanation;

-Ballistic stretching uses the momentum of a moving body or a limb in an attempt to force it beyond its normal range of motion. It involves stretching by bouncing into (or out of) a stretched position, using the stretched muscles as a spring which pulls you out of the stretched position. An example is the ballistic method of touching your toes would be to bounce and move toward your feet.
