Q: What do nearly all nonsense mutations lead to ? Read this paragraph and choose the correct option from the provided answers: Choices: - dehydration - downs syndrome - hormone release - nonfunctional proteins A:
nonfunctional proteins

Q: Since warmer molecules have more energy, they are more what? Read this paragraph and choose the correct option from the provided answers: The density of air varies from place to place. Air density depends on several factors. One is temperature. Like other materials, warm air is less dense than cool air. Since warmer molecules have more energy, they are more active. The molecules bounce off each other and spread apart. Another factor that affects the density of air is altitude. Choices: - inactive - dense - abundant - active A:
active

Q: Q: What is used to measure electric current? Read this paragraph and choose the correct option from the provided answers: Choices: - atomizer - chronometer - anemometer - galvanometer A:
A: galvanometer

Question: Q: What is usually necessary to develop cancer? Read this paragraph and choose the correct option from the provided answers: Usually mutations in multiple genes are necessary to develop cancer. Choices: - crucial genes mutations - massive genes mutations - novel genes mutations - multiple genes mutations A:
Answer: multiple genes mutations

Q: What do we call an incorrect test result that should have been positive? Read this paragraph and choose the correct option from the provided answers: Cancer Proteomics Genomes and proteomes of patients suffering from specific diseases are being studied to understand the genetic basis of the disease. The most prominent disease being studied with proteomic approaches is cancer. Proteomic approaches are being used to improve screening and early detection of cancer; this is achieved by identifying proteins whose expression is affected by the disease process. An individual protein is called a biomarker, whereas a set of proteins with altered expression levels is called a protein signature. For a biomarker or protein signature to be useful as a candidate for early screening and detection of a cancer, it must be secreted in body fluids, such as sweat, blood, or urine, such that largescale screenings can be performed in a non-invasive fashion. The current problem with using biomarkers for the early detection of cancer is the high rate of false-negative results. A false negative is an incorrect test result that should have been positive. In other words, many cases of cancer go undetected, which makes biomarkers unreliable. Some examples of protein biomarkers used in cancer detection are CA-125 for ovarian cancer and PSA for prostate cancer. Protein signatures may be more reliable than biomarkers to detect cancer cells. Proteomics is also being used to develop individualized treatment plans, which involves the prediction of whether or not an individual will respond to specific drugs and the side effects that the individual may experience. Proteomics is also being used to predict the possibility of disease recurrence. The National Cancer Institute has developed programs to improve the detection and treatment of cancer. The Clinical Proteomic Technologies for Cancer and the Early Detection Research Network are efforts to identify protein signatures specific to different types of cancers. The Biomedical Proteomics Program is designed to identify protein signatures and design effective therapies for cancer patients. Choices: - external positive - false positive - personal negative - false negative A:
**Answer**
false negative

Q: Most motions in nature follow ________ rather than straight lines? Read this paragraph and choose the correct option from the provided answers: Introduction to Two-Dimensional Kinematics The arc of a basketball, the orbit of a satellite, a bicycle rounding a curve, a swimmer diving into a pool, blood gushing out of a wound, and a puppy chasing its tail are but a few examples of motions along curved paths. In fact, most motions in nature follow curved paths rather than straight lines. Motion along a curved path on a flat surface or a plane (such as that of a ball on a pool table or a skater on an ice rink) is two-dimensional, and thus described by two-dimensional kinematics. Motion not confined to a plane, such as a car following a winding mountain road, is described by three-dimensional kinematics. Both two- and threedimensional kinematics are simple extensions of the one-dimensional kinematics developed for straight-line motion in the previous chapter. This simple extension will allow us to apply physics to many more situations, and it will also yield unexpected insights about nature. Choices: - vertical paths - sharp paths - horizontal paths - curved paths A:
(Answer)
curved paths
