Answer: Oxidative Phosphorylation
-------
Oxidative phosphorylation is the last step of aerobic cellular respiration and is when most of the ATP is created. The electrons from NADH and FADH2 power the proton pumps, which transfer H+ into the matrix that power ATP synthase to make ATP.
Ecosystem
Explanation:
The relationship between the living and non-living things forms an ecosystem.
The non- living things like water, air, soil and other are required by the living organisms for leading their life cycle.
The living things forms the integral part of the natural cycling process of water, air and soil.
Thus this can be said that both living and non-living things are interdependent on each other and forms an ecosystem.
For example, if plants do not get water they will not be able to produce food also the transpiration will not occur which is an important part of the water cycle.
Sexual reproduction. Like most mammals, giraffes produce sexually, meaning that both parents contribute to the DNA of the offspring.
Whereas, female offsprings inherit X chromosome ( from each parent). As per the question, family has Y linked disease that affects father. Thus, there will be 100% chances of inheriting this disease by the male offspring.
