Answer:
C- Protein
Explanation:
Peptide bond -
The bond between the carbonyl group and the the amine group , is referred to as peptide bond .
Peptide bond is written as -
--CONH --
From the molecules given in the question , protein molecule has peptide bond .
Since ,
protein molecules are composed of amino acid chains via some force of interactions ,
And , since , amino acid have a peptide bond .
Bleach

A base removes hydrogen ions from a solution
A base decreases the hydrogen ion concentration in a solution
on a ph scale something is basic if it's measured 8-14
The ionization of the following acids and bases can be expressed as follows :
(A ) HI + water →← H + (aq) + I -(aq)
(B) KOH + H2O →← K+(aq) + OH- (aq)
(C)HNO2(l) + H2O →← H+(aq) +NO2-(aq)
(D)H2PO4- + H2O →← H + (aq) + HPO4 ^2- (aq)
(E)CHNH2 + H2O→← CH3NH3+(aq) + OH-(aq)
(F)CH3CH2COOH +H2O→←CH3CH2COO-(aq) + H3O+(aq)
The first and the last choice is the same, aren't they?
Answer:
O D. It has an -OH group attached to the end of the molecule.
Explanation:
Some alcohols have hydroxyl group (OH) attached to the end of a molecule and some have it attached as a branch on the molecule
- R is aryl or alkyl group
- OH is hydroxyl group
