The formation of a peptide bond between two amino acids is an example of: o group transfer o isomerization a condensation reaction 0 cleavage

condensation reaction

Explanation:

Condensation reaction

The type of reaction in which two or more reactants merge to form a single product , via removal of small molecules like water ammonia , is called a condensation reaction .

Hence ,

A peptide bond is formed by merging two amino acids together by the removal of water molecule to form a peptide bond , hence it is a type of condensation reaction .

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.

geosphere and hydrosphere.

this is because the geosphere has to do with geological events, while the hydrosphere controls all water on earth.
