Which three components are common to all amino acids? a. an amino group, a carboxyl group, and an r group b. an amino group, a phosphate group, and an r group c. a five-carbon sugar, a phosphate group, and a nitrogenous base d. a five-carbon sugar, an amino group, and a nitrogenous base

The correct answer is A.  an amino group, a carboxyl group, and an R group

An amino acid is a unit or building block of a protein. There are 20 different types of amino acids present and all amino acids composed of five basic parts. These are a central carbon (C) atom, a hydrogen(H) atom, an amino group (NH₂) having one nitrogen atom and two hydrogen atoms, a carboxyl group (COOH) having one carbon atom, two oxygen atoms, and one hydrogen atom and a R-group or side chain.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
