What makes up an atom?
Protons, neutrons, electrons
Name the 3 parts of the cell theory
All organisms are composed of one or more cells, Cells are the most basic unit of structure and function in organisms, All cells come from only other cells
The plasma membrane is composed of
Phospholipids and proteins
List 2 strengths of science
Publicly understandable, Antiauthoritarian, Self-correcting, Predictive
Scans, radiation therapy
Cellular respiration is best associated with what part of the cell?
Mitochondria
Location of proteins in the plasma membrane
Float inside or within the phospholipid bilayer
What is the difference between inductive and deductive reasoning?
Deductive— big ideas —> specific results
What is the difference between polar and nonpolar covalent bonds?
Polar— electrons are not shared equally, Nonpolar— electrons shared equally
In order to digest materials within a cell, the material to be digested must fuse with
A lysosome
Function of a carrier protein
Combine with a substance and help it move across the membrane
What is the control group in the stomach ulcer example?
Cohesion vs adhesion
Cohesion— cling together, adhesion— adheres to polar surfaces
The innermost membrane of the chloroplast is referred to as the
Thylakoid membrane
Definition of diffusion and osmosis
Diffusion— movement of molecules from a higher to a lower concentration gradient, Osmosis— diffusion of water through a selectively permeable membrane

Acidic vs basic solutions
Acidic— High H+ concentrations, below 7 on the pH scale, Basic— Low H+ concentrations, above 7 on the pH scale
Proteins are processed and modified in the interior of the
Rough endoplasmic reticulum
Intestinal cell ingests substances inside very small vesicles that can only be seen with an electron microscope
Pinocytosis
