Superficial
Medial
Proximal

The process of homeostatic regulation operates most often through a system of:
Positive feedback
Negative feedback
Situs inversus
Respiration
A chemical compound contains at least two:
Protons
Ionic bonds
Molecules
Elements
The atomic number of an element is determined by:
The number of neurons in the nucleus
The number of electrons is contains
Its atomic weight
The number of protons in the nucleus
Ionic bonds are formed when:
One atom transfers an electron from its outer shell to another atom
Two atoms share one or more pairs of electrons
Two anions meet
Two elements are dissolved in water
Electrolytes are:
Elements tat contain an extra neutron
Compounds that dissociate in water
The building blocks of protein
Atoms joined together by covalent bonds
What is the name of the process used to break down complex compounds into simpler ones to release energy?
Catabolism
Anabolism
Metabolism
Ionization
Which is the most abundant inorganic compound in the body?
Carbohydrates
Proteins
Water
Lipids
Which type of substance releases a hydrogen ion when dissolved in water?
Base
Salt
Electrolyte
acid
What is the body's main source of energy?
The body stores glucose in the form of:
Starch
Galactose
Cellulose
Glycogen
How do cells obtain the energy they need?
They receive energy directly from the catabolism of nutrients from food
They receive energy when ATP is ingested in the diet
They receive energy when the phosphate bonds of ATP are broken
Cells don't need an outside supply of energy
The nucleus of the cell is called the control center because it:
Controls the function of all the organelles in the cells
Contains all the genetic material for the cell
Regulates the flow of substances into and out of the cell
Resides at the center of the cell
The plasma Membrane is made up of:
A rigid layer of protein
A double layer of protein and cholesterol
A double layer of phospholipids with cholesterol and proteins embedded at various spots
A rigid layer of carbohydrates and protein
What is the chief purpose of the Golgi apparatus?
Prepare and package proteins in vesicles for export to other parts of the body
Synthesize proteins
Break down protein the cell doesn't need
Participate in cell division
What is the function of the mitochondria?
To destroy bacteria
To burn ATP for energy
To store ATP
To convert organic compounds into ATP
The hair-like processes on the surface of the cell that beat in waves to help propel materials across its surface are called:
Microvilli
Flagella
Cilia
Centrioles
Which of the following correctly describe diffusion?
It is a form of transport in which water moves from an area of higher to lower concentration
It is a form of active transport in which particles moves from an area of higher to lower concentration
It is a form of passive transport in which particles moves from an area of higher to lower concentration
It is a form of passive transport in which particles pass through channels on the cell membrane to move from an area of higher to lower concentration
Osmotic pressure is the:
force that drives osmosis
Force that drives solutes through capillary walls
Pressure that aids in venous return
Water pressure that develops as a result of osmosis
If red blood cells are immersed in a hypertonic solution, the cells will:
Remain normal in size and water content
Lose fluid and shrivel
Swell and possibly burst
Diffuse through capillary walls
