Write down four fuctions of water learned in life sciences class​

See explanation

Explanation:

Water is a polar solvent and is also called a universal solvent because of its ability to dissolve several substances especially in the body.

The functions of water learned in the life sciences class include;

1. Water is the medium for biochemical reactions

2. Most substances in the body are transported from place to place by water.

3. Water acts a solvent for many biologically important substances in the body.

4. Water is necessary in helping animals to regulate their body temperature.

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
