Electrons are brought to the electron transport system by the oxidation of NADH and FADH2.
The electron transport chain is a group of proteins located within the inner membrane of the mitochondria which transport electrons. Electrons are passed from one member of the transport chain to another in a series of redox reactions, forming a proton gradient which is then used for ATP production.
NADH and FADH2 are reduced electron carriers which are oxidized into NAD+ and FAD near the beginning of the electron transport chain.
The correct option is this: THE ORDER OF THE CODON DIFFERS BETWEEN ORGANISMS.
Codon refers to a sequence of three DNA, which corresponds to a particular amino acid or a stop signal. The same base pair are present in all living organisms, but in each organism, the base pair are mixed in different orders, this results in variations in the living organisms that are formed.

Bacterial binary fission is similar in some ways to the mitosis that happens in humans and other eukaryotes. In both cases, chromosomes are copied and separated, and the cell divides its cytoplasm to form two new cells. However, the mechanics and sequence of the two processes are fairly different.
Answer:
Half-life, in radioactivity, the interval of time required for one-half of the atomic nuclei of a radioactive sample to decay (change spontaneously into other nuclear species by emitting particles and energy), or, equivalently, the time interval required for the number of disintegrations per second of a radioactive
Explanation:
