The true answer of your question is :
OH : HYDROXYL GROUP
NH2 : AMINO GROUP
CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )
COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

A chemical formula is obtained from the number of atoms in a compound.
Chemical compounds are composed of atoms. The number atoms of each element in a compound determines the correct formula of the compound. Before I can write the chemical formula of any compound, I must first determine the number of each atom in the compound.
For instance, phosphorus trichloride contains one atom of phosphorus and three atoms of chlorine hence I would place a 1 in the box for P and 3 in the box for Cl.

Answer:
218.75 grams of protein.
Explanation:
If 2500 protein is consumed and its 35% energy is provided by protein then:
2500÷35×100 =875 kcal would be provided by protein.
As one gram of protein provide 4 kcal of energy:
875÷4 = 218.75 grams of potein would be consumed.
<em>Remeber the calories and kcal for food is same.</em>

Perhaps the answer is "physical characteristics". I am simply making an educated guess, however I do know early philosophers classified organisms into two groups, Plants and Animals, and identified them based on physical characteristics.
