the answer would be C by thr ionic bonding
<span>The answer is True. Doppler Effect is defined as “the change( increase of decrease) found in wave, sounds or light as the soure and observer slowly walks away. Examples of this would be ripples formed when ducks are swimming in the lake or the sound of the sirens, going higher as they moved to another destination</span>
<span> They can be classified according to the core structural functional groups' locations as </span><span>alpha- (α-), beta- (β-), gamma- (γ-) or delta-(δ-)</span><span> amino acids; other categories relate to </span>polarity<span>, </span>pH<span> level, and side-chain group type (</span>aliphatic<span>, </span>acyclic<span>, </span>aromatic, containing hydroxyl orsulfur<span>, etc.). In the form of </span>proteins<span>, amino acids comprise the second-largest component (water is the largest) of human </span>muscles<span>, </span>cells<span> and other </span>tissues.[5]<span> Outside proteins, amino acids perform critical roles in processes such as </span>neurotransmitter<span> transport and </span>biosynthesis<span>.</span>
