Answer: They are proteins, They can bind with substrate, and They act as catalysts.
Explanation:
.-. from what I can see, no :/. but then again I cant see the model for the dog if there isnt. But based of this, the Skeleton structure isnt within a same group class, but the Dolphin and Dog do share a similar inside, such as similar Lungs, Immune system, both require air to breath (despite the dolphins ability to live in water)
Well one is the ways that humans use soil affect the soil quality
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.
I hope you’ll understand everything, anyway if not i’m always here to help. ♥️
