In studying a particular biomolecule (a protein, nucleic acid, carbohydrate, or lipid) in the laboratory, the biochemist first needs to separate it from other biomolecules in the sample (that is, it needs to be purified). specific purification techniques are described later in the text. however, by looking at the monomeric subunits and functional groups of a biomolecule, you should have some ideas about the characteristics of the molecule that would allow you to separate it from other molecules. look for differences in ionizable groups, polarity, solubility in water, size, and shape. based on the characteristics of each type of molecule, select the way(s) in which amino sugars such as glucosamine could be separated from steroid hormones such as estradiol

any abiotic or biotic factor in an ecosystem that causes a population's size to slow or decrease is a limiting factor.

i might be wrong but i think its a. let me know if i’m right and have a good rest of your day!

enzyme active site and substrate specificity

enzymes bind with chemical reactants called substrates. there may be one or more substrates for each type of enzyme, depending on the particular chemical reaction. in some reactions, a single-reactant substrate is broken down into multiple products

phaneritic textures in which phaner means visible so phaneritic textures are standard of impertinent volcanic rocks. these rocks crystallized gradually under the surface of earth. when the magma cools deliberately then the ores have chance to develop and produce long crystals.
