The answer is alpha hemolysis. The other types of hemolysis are beta and gamma hemolysis. While beta hemolysis leaves a clear zone in the area around the bacterial growth, gamma hemolysis indicates that there is a lack of hemolysis and thus the agar is unchanged in the vicinity of a bacterial colony.
Answer: Option D is the correct answer.
Explanation:
Animals are not the first to colonize land. Prokaryote are probable the first organisms to colonize land. They have been existing about 2.6 billions years ago. Fungi have been in existence long time ago. Study reveals that they have been living in aquatic habitat before coming to colonize the land.
1. it might be so hot, that rain clouds may not form to create rain, resulting in drought.
2. if it does rain, the water would just evaporate into air, or just go into the dirt.
3. it might dry up the rain on a steep hill or patch of land, and cause a land slide since the rain wouldn't make the dirt kinda moist to keep it stiff with the pressure of anything built on top of it, like cement. if the land was dry, it would crumble up, and everything around it would be destroyed.
Answer:
e. Researchers suspect that portions of the reverse cycle may have been responsible for fixing CO2
Explanation:
Carbon fixation refers to the metabolic process by which inorganic carbon, especially carbon dioxide (CO2), is converted to organic matter. Moreover, the citric acid cycle (TCA) is a metabolic pathway capable of generating energy by the oxidation of acetate (which is derived from carbohydrates, fats, and proteins) into CO2. The reverse TCA cycle is a form of carbon fixation that uses CO2 and water molecules to produce organic carbon molecules. The enzymes that are unique to the reverse TCA cycle include ATP citrate lyase (required to cleave citrate into acetyl CoA and oxalacetate); 2-oxoglutarate:ferredoxin oxidoreductase (OGOR); and pyruvate ferredoxin oxidoreductase (required for pyruvate decarboxylation/oxidation).
Answer:
using crop rotation
Explanation:
Crop rotation involves alternating the crops grown on a piece of land after every season. It helps to maintain soil fertility since different croms remove different minerals from it. Legumes should be included in the rotation as they replenish the nitrogen supply in the soil. This method of farming increases food production.
