Answer:
Xe
Explanation:
Cs and Na are solids in room temperature while F and Xe are gases.
The number of electrons in the outermost shell of an atom will determine its reactivity. Out of the gases given Xe and F, F ( the most electronegative element) posses 5 valence shell electrons which makes it highly reactive while Xe which is a noble gas posses 8 valence shell electrons which makes it less reactive compared to many elements.
Mitosis and cytokinesis divide a parent cell into two IDENTICAL daughter cells
I believe that the most contaminated are is the kitchen sink. Researchers say that the sink can contain up to 100,000 times more bacteria than the toilet seat. This is because the sink is where everything is slopped in.The sink should be washed with hot water and disinfected regularly to kill the harmful bacteria.
Answer:
<h2>B</h2>
Explanation:
Glycolysis is the process of production of pyruvate from glucose by various enzymatic steps.
This pyruvate is further used in different ways; as it is differently used in the presence of oxygen or in the absence of oxygen.
In the absence of oxygen, lactate is generated form pyruvate, as given here, if this enzyme is non-functional, then lactate would not be produced.
In the presence of oxygen, pyruvate is oxidized in TCA cycle and finally through electron transport chain, energy in generated.
