What are the precursors that make up macromolecules? a. polymers b. sulfates c. carbohydrates d. monomers

First option A) Polymers

Option D is correct.

D.monomers

When small organic molecules bind together, they form larger molecules called biological macromolecules. Biological macromolecules fall into four categories: carbohydrates, proteins, lipids and nucleic acids.

Macromolecules are formed by repeating sub units called monomers.

this protocol describes a detailed procedure for intracellular flow cytometry staining.

straight probes are used primarily for measuring flow as it is approaching the test area. its geometry allows the probe to be mounted so that it is in the direct line of airflow.
