Document Summary

A test to seek natural causes to explain how the world works. Ca(cid:374)"t tell us (cid:449)hat is (cid:373)orall(cid:455) right or (cid:449)ro(cid:374)g.

Ionic bonds: mutual attraction between ions with opposite charges. Ion: atom with a net charge (proton- electron) Ionization: one or more electrons transferred from one neutral atom to another. A scale that measures the hydrogen ion concentration. Acidic releases hydrogen ion into water (proton donor) Contains a carboxyl end and an amino end. Covalent: strongest bond in nature held together by shared electrons to stabilize an atom. Golgi apparatus: synthesis, package and release protein and lipid. Golgi body: protein and lipid enters the cytoplasm. A cell must use energy to move molecules against a concentration gradient. Ions and molecules move down a concentration gradient without any energy input.
