Answer:
2 is correct if I'm not mistaken
The answer would be: <span>A viral load of 1,200 copies/mL
</span>
Viral load determines the number of HIV virus that can be found in every mililiters of blood. More virus means more risk of <span>transmission</span>. A vaginal delivery will cause much more blood than cesarean delivery. The contact of the blood and the baby cause vaginal delivery is more dangerous than cesarean.
Nitrogen Cycle steps:
N molecules breaking apart via nitrogen-fixing bacteria.
Animals ingest nitrogen in nitrate-containing food after plants use nitrogen-containing compounds.
The organic matter decays via decomposers
N2 is formed via denitrifying bacteria.
Explanation:
The nitrogen-fixing bacteria removes atmospheric nitrogen by fixing nitrogen through nitrification. The atmospheric nitrogen cannot be absorbed by plants and hence has to be converted into nitrates. This conversion takes place by nitrifying bacteria present in leguminous plants.
Animals (herbivores) consume the plants that have absorbed nitrogen/
When these animals die, decomposing bacteria acts on the dead organic matter, decomposition takes place through ammonification, converting the organic nitrates into ammonia
The nitrates are converted back again to nitrogen by the action of denitrifying bacteria.
The nitrogen thus formed is released to the atmosphere
Answer:
Industrial Revolution
Explanation:
In the 18th century, the industrial revolution took place. People started having more jobs than before and also getting paid for their labor. As the workers and employees were getting paid and jobs were available because of the industrial revolution, people started buying goods for their families. As a result, the standard of living also went up. Also, there was enough food for families to grow. As a result, the total population increased. In the 18th century, for the first time, the total population reached 1 billion landmarks.
