Sodium has one electron in its outer energy level. According to the octet rule, _____.
Answers
A sodium atom has a single electron in its outermost electron shell, the first and second shells again being full with two and eight electrons respectively. To remove this outer electron requires only the first ionization energy, which is +495.8 kJ per mole of sodium atoms, a small amount of energy. By contrast, the second electron resides in the deeper second electron shell, and the second ionization energy required for its removal is much larger: +4562.4 kJ per mole. Thus sodium will, in most cases, form a compound in which it has lost a single electron and have a full outer shell of eight electrons, or octet.
Answer : According to the octet rule, sodium wants to lose an electron.
Explanation :
The given element is sodium with atomic number 11 that means it has 11 electrons.
The electronic configuration of sodium will be,
From the electronic configuration, we see that one electron of sodium present in its outer energy level. Sodium can be lose one electron easily for the stable electronic configuration.
According to the octet rule, sodium has the tendency to lose one electron and form positive ion with the charge (+1).
Hence, according to the octet rule, sodium wants to lose an electron.

Although uncommon, it's possible to drink too much water. When your kidneys can't excrete the excess water, the sodium content of your blood is diluted (hyponatremia) — which can be life-threatening.

Breathing in too much carbon monoxide will most likely result in the production of less ATP.
How breathing carbon monoxide can affect production of ATP?
Carbon monoxide reduces the amount of oxygen that can be transported to cells.
Cell generates ATP from the process of cellular respiration in the mitochondria.
Aerobic respiration use glucose and oxygen to form ATP.
If the amount of oxygen is reduced, then it will directly affect the cellular respiration and hence, the production of ATP.

-a scientific question is a hypothesis. which has to be testable.
Explanation;
-A scientific question is a question that may lead to a hypothesis and help us in answering (or figuring out) the reason for some observation. A hypothesis is a tentative, testable answer to a scientific question.
-A good scientific question has certain characteristics. It should have some answers (real answers), should be testable (i.e, it can be tested by another individual through an experiment or measurement), leads to a hypothesis that is falsifiable (i.e. it should generate a hypothesis that can be shown to fail), etc.

Answer:
The correct answer would be the proton gradient.
Oxidation of NADH and FADH₂ release high energy electrons which are passed through the electron transport chain.
Some of the energy of these free electrons are used to form a proton gradient across the inner membrane of mitochondria in which the enzyme ATP synthase is placed.
The protons from the inter-membrane space pass down the concentration gradient through ATP synthase.
The movement of protons (charged particles) down the concentration gradient produces energy some of which is used by ATP synthase in order to phosphorylate ADP into ATP.

Answer:
The correct answer would be hydrologic cycle (hydro means "related to water").
Hydrologic cycle or water cycle refers to the cyclic movement of water in an ecosystem.
The physical processes involved in the cycling of water throughout the ecosystem are: evaporation, condensation, sublimation, precipitation, infiltration, and runoff (surface and sub-surface).
Water evaporates from the surface of the earth into the atmosphere where they condense to form clouds. When temperature decreases, the water droplets merge with each other to form bigger droplets which are precipitated in the form of rain.
Water can also precipitate in the form of snow, fog, hail sleet et cetera.
Water fall on the earth surface either infiltrate to form ground water or runoff the surface to from lakes, rivers et cetera.
