Paul [167]

Answer:

It represents the first stage in the chemical oxidation of glucose by a cell.

Explanation:

Glycolysis is the first stage of oxidation of glucose by the process of cellular respiration. Glycolysis includes the breakdown of one molecule of glucose into two molecules of pyruvate. Substrate level phosphorylation forms net 2 ATP molecules and the redox reactions of glycolysis uses NAD+ as an electron acceptor resulting in the formation of 2 NADH.

Therefore, one molecule of glucose obtains 2 pyruvate molecules, 2ATP and 2 NADH by glycolysis. The fate of pyruvate depends on the availability of oxygen. Citric acid cycle and oxidative phosphorylation are the next two stages of aerobic cellular respiration.

Why is the back-work ratio much higher in the brayton cycle than in the rankine cycle?
Ivanshal [37]

The back-work ratio much higher in the brayton cycle than in the rankine cycle because a gas cycle is the Brayton cycle, while a steam cycle is the Rankine cycle. Particularly, the creation of water droplets will be a constraint on the steam turbine's efficiency. Since gas has a bigger specific volume than steam, the compressor will have to work harder while using gas.

Recall the steady flow device's shaft work expression.

W =-∫ V dP +...

As it is in the pump (liquid) compared to turbine (superheated vapor) in the Rankine cycle, the specific volume in the compressor is not significantly less than the specific volume in the turbine in the Brayton cycle.

A thermodynamic cycle that transforms heat into mechanical energy is the Rankine cycle, often known as the Rankine vapor cycle.

The operation of various heat engines that use air or another gas as their working fluid is described by the Brayton cycle, a thermodynamic cycle.

In a particular woodland community, two species of rodents coexist: mice and chipmunks. Both species compete for the same kinds
scZoUnD [109]

Answer:

First, we take the owl out, the total number of mouse increases at a higher rate and the chipmunks are also decreasing in numbers. In an ideal ecosystem, both mice (lets call it "a") and chipmunks (lets call it "b") should increase since the restraining factor has been removed. But that is the opposite of what we should see. In that case, we will take the owl to be the "limiting factor" for the rodents.

Am

The rodents will have free movement and exercise their fitness over the area, competition sets in between the two species. So we see, a flourishes while b dies out. This can be viewed most predictably that a has an overall greater fitness and would easily get resources and strive readily, which influences the survival rate for 2.
