How do the digestive system and the respiratory system help generate energy from food? Question 2 options:

The respiratory system breaks food into nutrients, while the digestive system provides oxygen to process the nutrients.

The digestive system breaks food into nutrients, while the respiratory system provides oxygen to process the nutrients.

The respiratory system supplies the nutrients from food to various tissues, while the digestive system helps in combustion of nutrients.

hloride, what is the mass of calcium in

explanation:

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.

that tool would be a compass
