AC-HPAT Biology Exam Questions With
Correct Answers
Pancreas and Type 1 diabetes - CORRECT ANSWER✔✔-The pancreas is the organ
| | | | | | | | | | | |
that produces insulin, and it plays a major role in regulating blood glucose levels.
| | | | | | | | | | | | | |
Type 1 diabetes occurs when the pancreas does not make enough or any insulin.
| | | | | | | | | | | | |
How does insulin work in diabetes? - CORRECT ANSWER✔✔-Insulin pumps are
| | | | | | | | | | |
small, computerized devices that mimic the way the human pancreas works by
| | | | | | | | | | | |
delivering small doses of short acting insulin continuously (basal rate). The device
| | | | | | | | | | | |
also is used to deliver variable amounts of insulin when a meal is eaten (bolus)
| | | | | | | | | | | | | |
chemotherapy - CORRECT ANSWER✔✔-Chemotherapy is a drug treatment that| | | | | | | | |
uses powerful chemicals to kill fast-growing cells in your body. Chemotherapy is
| | | | | | | | | | | |
most often used to treat cancer, since cancer cells grow and multiply much more
| | | | | | | | | | | | | |
quickly than most cells in the body. It targets cells that grow and divide quickly, as
| | | | | | | | | | | | | | |
cancer cells do. Unlike radiation or surgery, which target specific areas, chemo
| | | | | | | | | | | | |
can work throughout your body. But it can also affect some fast-growing healthy
| | | | | | | | | | | | |
cells, like those of the skin, hair, intestines, and bone marrow.
| | | | | | | | | |
How can stem cells be used in the treatment of leukemia? And how effective is it?
| | | | | | | | | | | | | | |
- CORRECT ANSWER✔✔-Stem cell transplant replaces the leukemia cells in your
| | | | | | | | | | | |
bone marrow with new ones that make blood. Your doctor can get the new stem
| | | | | | | | | | | | | | |
cells from your own body or from a donor. Stem cell transplantation is effective
| | | | | | | | | | | | | |
against leukemia. In many cases, however, the transferred immune cells of the
| | | | | | | | | | | |
donor also attack the recipients' healthy tissue—often with fatal consequences. ...
| | | | | | | | | |
,Stem cell therapy offers people suffering from leukemia or bone-marrow cancer
| | | | | | | | | | | |
the chance of full recovery.
| | | |
Why is laser technology more effective than conventional surgery in removing
| | | | | | | | | | |
cancerous tumours? - CORRECT ANSWER✔✔-Lasers are more precise than
| | | | | | | | |
standard surgical tools (scalpels), so they do less damage to normal tissues. As a
| | | | | | | | | | | | | |
result, patients usually have less pain, bleeding, swelling, and scarring. With laser
| | | | | | | | | | | |
therapy, operations are usually shorter.
| | | |
Urinary system - CORRECT ANSWER✔✔-· The urinary system, also known as the
| | | | | | | | | | | |
renal system or urinary tract, consists of the kidneys, ureters, bladder, and the
| | | | | | | | | | | | |
urethra. The purpose of the urinary system is to eliminate waste from the body,
| | | | | | | | | | | | | |
regulate blood volume and blood pressure, control levels of electrolytes and
| | | | | | | | | | |
metabolites, and regulate blood pH | | | |
Nanotechnology - CORRECT ANSWER✔✔-Nanotechnology can provide rapid and | | | | | | | |
sensitive detection of cancer-related molecules, enabling scientists to detect
| | | | | | | | |
molecular changes even when they occur only in a small percentage of cells.
| | | | | | | | | | | |
Mercury poisoning - CORRECT ANSWER✔✔-The most common cause of mercury
| | | | | | | | | |
poisoning is from consuming too much methyl mercury or organic mercury, which
| | | | | | | | | | |
|is linked to eating seafood. Small amounts of mercury are present in everyday
| | | | | | | | | | | | |
foods and products, which may not affect your health. Too much mercury,
| | | | | | | | | | | |
however, can be poisonous. Mercury salts affect primarily the gastrointestinal
| | | | | | | | | |
tract and the kidneys, and can cause severe kidney damage; however, as they
| | | | | | | | | | | | |
cannot cross the blood-brain barrier easily, these salts inflict little neurological
| | | | | | | | | | |
damage without continuous or heavy exposure.
| | | | |
, How can ultraviolet light from the sun affect the cells of the human eye? -
| | | | | | | | | | | | | | |
CORRECT ANSWER✔✔-UV rays may lead to macular degeneration, a leading
| | | | | | | | | |
cause of vision loss for older Americans. UV rays, especially UV-B rays, may also
| | | | | | | | | | | | | |
cause some kinds of cataracts. A cataract is a clouding of the eye's natural lens,
| | | | | | | | | | | | | | |
the part of the eye that focuses the light we see.
| | | | | | | | | |
Macromolecules - CORRECT ANSWER✔✔-Macromolecules are large molecules | | | | | | |
composed of thousands of covalently connected atoms. Carbohydrates, lipids,
| | | | | | | | |
proteins, and nucleic acids are all macromolecules. Macromolecules are formed
| | | | | | | | | |
by many monomers linking together, forming a polymer.
| | | | | | |
passive transport - CORRECT ANSWER✔✔-Passive transport is a movement of
| | | | | | | | | |
ions and other atomic or molecular substances across cell membranes without
| | | | | | | | | | |
need of energy input. Unlike active transport, it does not require an input of
| | | | | | | | | | | | | |
cellular energy because it is instead driven by the tendency of the system to grow
| | | | | | | | | | | | | |
|in entropy.
|
active transport - CORRECT ANSWER✔✔-active transport is the movement of
| | | | | | | | | |
molecules across a membrane from a region of lower concentration to a region of
| | | | | | | | | | | | |
higher concentration—against the concentration gradient. Active transport
| | | | | | | |
requires cellular energy to achieve this movement.
| | | | | |
catalyst - CORRECT ANSWER✔✔-Catalyst: a substance that increases the rate of a
| | | | | | | | | | | |
chemical reaction without itself undergoing any permanent chemical change.
| | | | | | | |
fluid mosaic model - CORRECT ANSWER✔✔-describes the structure of the plasma
| | | | | | | | | |
|membrane as a mosaic of components —including phospholipids, cholesterol,
| | | | | | | | |
proteins, and carbohydrates—that gives the membrane a fluid character. The
