Biome1: ________Tropical Savannah____________
IceJOKER [234]
EcosystemTropical Savanna is found between sections of tropical rain forest and deserts.  They have 2 seasons; wet (constant humidity) and dry (long periods of dry spells and drought that may cause fires).

Both savanna buffalo and forest buffalo live close to water. The buffalo are found throughout the northern and southern savanna as well as the lowland rain forest.
<span>How might this population suddenly increase? How might this affect the ecosystem?  If there was an increase in population; grasslands during the wet season will be gone, more predators will flock for an abundance of buffalo.
</span>
<span>What might happen to the ecosystem if this population was removed?  If you remove the buffalo from the savanna ecosystem, it can cause a ripple effect such as populations of small mammal (mouse) will double, which will attract more snakes (venomous), it can cause the flea and tick population to increase, and the increase in tick/fleas can cause the risk of transmission of flea/tick borne pathogens.</span>

svp [43]

<u>Answer:</u>

<em>Ocean water is sinking at the North Atlantic Buoy Station the given things have occurred.</em>  

<u>Explanation:</u>

The way of thermohaline course starts at high scopes, where cold seawater sinks due to its generally high thickness.  

In the Northern Hemisphere, profound sinking to 2000-3000 meters happens just in the North Atlantic, not in the North Pacific on the grounds that the waters of the North Pacific are freezing and not as salty as the waters of the North Atlantic.  

In this way, Earth's profound sea bowls are loaded up with waters from the northern North Atlantic and those that sink close to Antarctica.

Answer:

The suitable option will be - B

Citric acid cycle

Explanation:

The results were -

Glucose: None

CO2: Increase

O2: None

ATP: Increase

NADH: Increase

  • We know that the Citric acid cycle is also known as the TCA cycle (tricarboxylic acid cycle) or the Krebs cycle. This cycle occurs in Mitochondria in case of eukaryotes. In this cycle acetyl-CoA is oxidized which comes from carbohydrates, proteins and fats and energy is released in the form of ATP.  
  • water is also used in this process. NAD+ gets reduced to NADPH. In this system carbon dioxide is produced as a waste byproduct. ATP is produced as the main product. ATP is also used as a source of energy.
