What is a tumor said to be when it shows signs of spreading?
What four major factors together account for as many as 98% of all cancer deaths?
hereditary defects, nutrition, smoking of drug abuse, and viruses
At present, what is one of the most important factors in treating cancer?
Treat the cancer early, before it has spread.
What are some preventions for cancer?
Avoid smoking, eat a healthy and balanced diet with plenty of vegetables, and exercise regularly.
What diseases are those in which the invading microbe can be transferred from person to person?
What diseases are caused by microorganisms that are not transferred from one person to another?
What microscopic unicellular creatures are some of the most widespread organisms i all of God's creations?
What cells have a membrane-bound nucleus and other membrane-enclosed cell parts?
In what cells does the nucleus lack a membrane, and instead the nuclear material is clumped in a dense region of the cell called the nucleoid?
What are bacteria considered when they are capable of motion?
What spherical-shaped bacteria usually grows in clusters or chains?
What are rod-shaped bacteria?
What are spiral-shaped bacteria?
In what asexual process are bacteria able to reproduce rabidly?
What small bacteria are identical to other bacteria in structure, but reproduce only inside other living cells?
What bacteria which live where air is present and obtain their oxygen from the heir are called aerobic bacteria?
What bacteria live in the absence of of oxygen?
What famous french scientist observed that bacteria sometimes spoiled wine by turning into vinegar?
Who developed the techniques scientists needed in order to study bacteria safely?
Who do we call the first great bacteriologist?
What is Koch's procedure known as?
What is the simplest way bacteria harm the cells of the infected individual?
stealing the cell's nutrients
What is another way to harm cells of the infected individual?
producing harmful substances
What is a third way that bacteria can cause harm to the cell?
By turning issues into a battleground.
What is a virus?
A virus is a molecule of genetic material (DNA or RNA) enclosed in a geometric protein structure called capsid
How are viruses manufactured?
Viruses are manufactured and assembled by infected cells.
What is a scientist who studies viruses?
What viruses are RNA viruses that use their RNA to to replicate viral DNA that is then inserted into the host cell's own chromosomes?
What single celled animals are responsible for several well-known diseases common in tropical regions?
What disease, for example, is caused by protozoa of the genus plasmodium?
What is one infection which is carried by water droplets, such as those discarded during a sneeze or a cough?

What are STD's?
sexually transmitted disease
What is one of the simplest ways to stop the spread of many diseases?
frequent hand washing
What is another method of disease prevention mentioned in the Scriptures?
avoiding unnecessary contact
What can also be used to prevent the spread of disease?
What special cells are programmed to search out and destroy any organism or substance that they do not recognize as a part of the body?
white blood cells
What complex network of fluid-filled vessel and chambers helps transport white blood cells throughout the body and aids the white blood cells in cleansing internal body fluids of pathogens?
What cells, also referred to as leukocytes, do the work of protecting your body against invaders?
white blood cells
God has designed the immune system with several types of white blood cells, each of which is designed to carry out a specific function.
What chemical messenger is produced by some white blood cells and mast cells when invading microorganisms or foreign substances are detected in the body?
What are an accumulation of lymph nodes in the throat to protect that port of entry to the body?
tonsils and adenoids
What occurs when your tonsils become infected?
What are lymph node groups located in the intestinal wall of the lower part of the small intestine?
What lymph organ is about the size of your fist and is located beneath the diaphragm just behind the stomach?
What lymphatic organ is located between the lugs above the heart?
What is a condition of resistance to a particular pathogen?
What are blood extracts that contain antibodies against a particular pathogen?
What type of immunity occurs because any pathogens infect only particular types of organisms?
