lina2011 [118]

<u>Answer:</u>

<em>Farmers definitely use the information above to plan out their crops from one year to next.</em>

<u>Explanation:</u>

Nitrogen is an essential nutrient required for healthy plant growth. Corn is an important food crop and after its cultivation the soil is depleted of its nitrogen. <em>Cultivation of any crop on soils that lack nitrogen will not yield good result.</em>  

Thus the nitrogen in the soil has to be replenished. Soybean is a crop that has symbiotic bacteria living on its roots. <em>This bacteria help in fixing atmospheric nitrogen.</em> Thus the nitrogen level will get replenished.  

Thus cultivating soybean on the land in the period between <em>harvest and sowing of corn would be a healthy practice that increases yield and maintains soil health.  </em>

brilliants [131]

Answer:

Explanation:

Why does your heart have to pump your blood to your lungs BEFORE it can pump it to the rest of the body?

The right side of your heart receives oxygen-poor blood from your veins and pumps it to your lungs, where it picks up oxygen and gets rid of carbon dioxide. The left side of your heart receives oxygen-rich blood from your lungs and pumps it through your arteries to the rest of your body.


what is responsible for pumping blood to the lungs?

The oxygen-poor blood fills the right atrium and then flows to the right ventricle, where it is pumped to the lungs through the pulmonary arteries. The lungs refresh the blood with a new supply of oxygen, which comes from the air that you breathe in.
