Answer:
Two reasons why the use of synthetic fertilizers is not the answer to decreasing soil quality are:
- They increase the nitrate levels in the soil which is a rich supplement for nitrogen needed by plants for their growth.
- They are easily available and user-friendly but should be used in regulated amounts as an excess of nutrients like nitrogen and phosphorus present in synthetic fertilizers enter the aquatic ecosystem.
<u>Explanation:
</u>
Synthetic fertilizers are made up of three main nutrients, viz, nitrogen, potassium and phosphorus. All of these are required for the proper growth of plants. Though, these fertilizers give higher yields, yet their excessive use is bad for aquatic ecosystems.
When these fertilizers are used in excessive amounts, they reduce the dissolved oxygen in the water as there’s an increase of bacteria and algae in the water. That is why such fertilizers should be used in regulated amounts.
Fruit flies produce offspring relatively fast and have specific traits, such as eye color and body color/shape. They are easy to observe and their traits are easily traced throughout the next generations.
A.) neutral
If the protein structure does not change then the function will not be affected either. The resulting effect is neutral because the shape and function was not altered.
HEMORRHAGE is the complication that can be caused by a dislodged clot from the incisional site.
Hemorrhage is a bleeding or abnormal flow of blood that might occur post-operation as a complication. This can be external or internal. The blood flow that occurs outside the body is called external hemorrhage while the blood flow that occurs inside the body is called internal hemorrhage.
