Answer:
1. Reactions involving oxidation and reduction along with proton pumping
2. Reactions involving phosphorylation and proton pumping
Explanation:
During oxidative phosphorylation, there is a transfer of electrons from donors to acceptors, which constitutes a redox reaction.
These redox reactions liberate energy that is utilized to produce ATP. In eukaryotic cells, these reactions are performed by protein complexes found in the mitochondria, while in prokaryotic cells, the proteins are positioned in the intermembrane space of the cells. These interconnected protein complexes are referred to as electron transport chains.
Answer:
It eliminates recoil.
Explanation:
Every action has a corresponding reaction that is equal and opposite.
According to the conservation of momentum, when a single spore is released, the fern experiences a recoil that diminishes the energy and velocity of the spore. However, by ejecting the spores in pairs, the recoil is neutralized, allowing the entire energy to be imparted to the spores, which leads to increased launch speeds.
The complete removal of all hawks allows for stabilization at a new equilibrium.
Response: a) 0.04 kW = 40 W
b) 0.05
Explanation:
A)
The thermal efficiency of the power cycle is calculated as Input / Output
Input = 10 kW + 14,400 kJ/min which translates to 10 kW + 14,400 kJ/(60s) = 10 kW + 14,400/60 kW.
Output equals 10 kW
Thus, Thermal Efficiency = Output / Input = 10 kW / 250 kW = 0.04 kW = 40 W
B)
Maximum Thermal Efficiency of the power cycle is defined as 1 - T1/T2
where T1 = 285 Kelvin
and T2 = 300 Kelvin
Thus, Maximum Thermal Efficiency = 1 - T1/T2 = 1 - 285/300 = 0.05
