I believe that a cell must use active transport to move molecules across the membrane against a gradient. Your answer should be D.
Answer:
Denitrification process occurs when the soil bacteria use nitrate for the respiration of oxygen in the air. These nitrates are converted to nitrogen gases.
<u>Explanation:
</u>
<em>The denitrification process mostly occurs in warm nature rapidly, wet soils with sufficient of nitrate. Denitrification process only occurs when the nitrate is present.</em> <em>The denitrification is in sewage treatment and it is beneficial process, the problem considered in agriculture farmers to increase their crop yields because they are applying nitrogen fertilizers to the land. </em>
<em>Denitrification process increases from cropland and it is responsible for increases the amount of nitrous oxide in the atmosphere. The denitrification process plays an important to recycling of nitrogen for healthy soil, microbial and for plant growth, and animal’s health.</em> The impacts of global warming are due to the process of denitrification through loss of nitrous oxide.
Answer:
I don't know the first one, i thought it would be quantitative but that's not an option
second one is scientific method
last one is science
The bronchi (singular: bronchus) are the airways that lead from the trachea into the lungs, and then branch into smaller bronchioles. Structurally, the bronchi are made up of cartilage that gives them stability and prevents their collapse.
