Answer:
The correct answer would be "NADH delivers its electrons to complex I and FADH₂ deliver its electrons to complex II" in cellular respiration.
There are mainly four complexes associated with electron transport chain of cellular respiration.
Complex I or NADH: ubiquinone oxidoreductase is the complex at which NADH is oxidized to form NAD⁺. The free electrons are transported with the help of ubiquinone.
Complex II or succinate dehydrogenase is the complex associated with oxidation of FADH₂ to FAD⁺. It also transports the free electrons with the help of the ubiquinone pool.
Complex III or cytochrome bc1 complex transport free electrons from ubiquinone to the cytochrome C which is a water-soluble electron carrier.
Complex IV or cytochrome c oxidase transport the free electrons to oxygen to form water.

Answer:
A. meiosis.
Explanation:
Meiosis is one of the two major types of cell divisions in living organisms. Meiosis is the process by which four daughter cells that are genetically different from the parent cell are produced. Meiotic process is carried out solely during sexual reproduction to yield gametes or sex cells.
The gametes have their chromosomal number reduced by half during the process. However, one immense importance of meiosis is that it PROMOTES GENETIC DIVERSITY. A process called crossing over, which is the exchange of chromosomal segment between non sister chromatids, makes this possible.
Organisms that use the same resources because there may not be enough for all, so it then becomes a competition of who gets it and who doesn't.
Autotroph is to producer as Hetrotroph is to consumer
Autotrophs make their own food, which makes them producers
While Hetrotrophs cannot make their own food, and must obtain it from another source, making them consumers
