Answer:
add 2 electrons
Explanation:
Add 2 electrons to carbide atom make it neutral because there are two unpaired electrons present in the carbide atom and it has -2 charge. So the carbide required two electrons for pairing and make the carbide atom neutral. for adding two electrons its all unpaired electrons paired to other two electrons which complete its valency and make it a stable atom.
T<span>he cell requires oxygen, and eukaryotic cells are expensive to run. they require a lot of energy and nutrients, and oxygen is one such component. the oxygen is necessary for aerobic respiration, which allows the cell to do a lot, including evolve, proliferate, adopt new niches, habitats, biochemical habitats, sustain life in extreme conditions, and perhaps eventually co-operate with other cells and create multicellular life. Multicellular life is virtually impossible without aerobic respiration. </span>
White blood cells increase as they are the cells that destroy pathogens
Answer:
The correct answer will be option-B.
Explanation:
Cellular respiration is a slow process which produces energy from the oxidation of food components which could be glucose, fatty acids and proteins.
The process proceeds in four steps: glycolysis, link reaction, Krebs cycle and electron transport chain.
The energy molecules are produced when a high energy electron gets reduced and the released energy is stored in the form of energy molecules which could be ATP or energy equivalents like NADH and FADH₂.
These reducing equivalents donate its electrons during electron transport chain where the electrons flow to the last electron acceptor called oxygen.
Thus, Option-B is the correct answer.
