AC-HPAT BIOLOGY 2024 QUESTIONS WITH COMPLETE SOLUTIONS GRADED A+ 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 ski n, 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 o wn 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 AC-HPAT BIOLOGY 2024 QUESTIONS WITH COMPLETE SOLUTIONS GRADED A+ 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 AC-HPAT BIOLOGY 2024 QUESTIONS WITH COMPLETE SOLUTIONS GRADED A+ 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 tog ether, 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.
