Degger [83]

Answer:

D. Fatty Acids

Explanation:

When fatty acids undergo beta-oxidation to serve as a source of ATPs, ketone bodies are produced. During starvation or medical conditions such as diabetes mellitus, carbohydrate supply to liver cells is depleted.

Once the stored glycogen has been depleted from the liver cells, the fatty acids are funneled into beta-oxidation to produce ATPs. The process also forms acetone,  acetoacetate, and D-beta-hydroxybutyrate, that is the ketone bodies. The more the fatty acid molecules enter the beta oxidation, the more ketone bodies are produced.

Quiz which condition could lead to drawdown below the level of existing wells?
irinina [24]

<u>Answer:</u>

Continuous pumping of water causes drawdown. The water table lowers rapidly.

<u>Explanation:</u>

  • Water table is the level below which the ground is saturated with water.
  • During rainfall the runoff water percolates into the ground through the gap in the soil particles and the water table is recharged.
  • But when gallons of water are pumped continuously it leads to a drastic reduction in the water table because, water from the surrounding aquifers move towards the place where the vacuum is created by pumping.
  • To prevent this, the groundwater should be recharged and over drawing should be avoided.

Was I correct? <br><br> The question was “What is the best solution for maintaining biodiversity?”
hoa [83]

Answer:

Yes

Explanation:

Indeed, <u>the best solution for maintaining biodiversity is to conserve the biodiversity of every ecosystem, since all ecosystems have benefits to humans and the earth</u>.

Ecosystems might vary in the kind of services they render to the planet or humans in general. For example, the forest ecosystems supply humans with the necessary timber and wood for construction purposes and sequestrate carbon/produce oxygen from and to the environment respectively. Thus, the forest ecosystem plays a huge role in maintaining the air quality of the planet in addition to several other services.

The variation in the services the different ecosystems render to the human population and the planet necessitates that the biodiversity of every one of them be conserved. Prioritizing the conservation of one over the other will result in losing some of the services provided as a result of loss of biodiversity.
