CSULB BME 100 Final Exam study guide 2024 latest update already graded A+

[T/F] While important for medicine, invention of penicillin or insulin has nothing to do with biomedical engineering. False [T/F] There is no drastic change in causes of death from 1900 to 2010. False [T/F] Electrocardiogram measures the electrical activity of the heart. Therefore we expect that the units on an Electrocardiogram diagram are Voltage (Ohm) vs Time (seconds, or min). False You may recall from physics that electro-magnetic waves (light, X-rays, etc) have a frequency. Energy (E) of a radiation can be described by the following simple equation E=hν . Where h is a constant (6.63 X 10-34 J.s) and ν is the frequency of a given electro-magnetic wave. Given the above select the False statement. a. The ratio of energy to frequency is a constant b. As the frequency increases the Energy of the radiation increases c. Given that X-ray has a higher energy than the red light; X-ray must have a shorter frequency than red light. d. frequency should have the units of (1/s) or dimension of (1/time) c. Given that X-ray has a higher energy than the red light; X-ray must have a shorter frequency than red light. Which is not considered a Biomedical engineering (BME) topic according to our class slides? a. Sequencing of genomic DNA b. Prosthetic devices and artificial limbs c. Tissue engineering d. All are considered BME topics d. All are considered BME topics [T/F] Ultrasound used ionizing radiation to enable imaging of biological samples (e.g., tissues) False [T/F] CT scan uses a series of MRI images to create a 3D image. False [T/F] Endothelial cells line surfaces in the body. False There are 3 ______ bonds between G-C in the complimentary base pairs between Nucleotides in the DNA ; and 2 ______ bonds between A-T. Therefore G-C are a ______ pair than A-T bonds. a. covalent, covalent, weaker b. hydrogen, hydrogen, stronger c. hydrogen, covalent, stronger d. covalent, covalent, stronger b. hydrogen, hydrogen, stronger [T/F] The lymphatic system also removes excess lymph fluid from bodily tissues, and returns it to the digestive system. False [T/F] RNA polymerase (RNAP) turns RNA into DNA. This process is called translation. False Think back to the video, "The immune systems explained". Which statement is False: a. Macrophages are described as "guard cells", that fight bacterial infection by each "eating up to 100" bacteria b. Macrophages recruit neutrophils if additional support is required c. Dendritic cells can activate helper t-cells, and in turn t-cells can activate b-cells d. B-cells are described as factories that create and release proteins known as antibiotics. Antibiotics get attached to the surface of bacteria. e. Memory helper t-cells and Memory b-cells remain in the body to combat the future similar infections f. All statements are true d. B-cells are described as factories that create and release proteins known as antibiotics. Antibiotics get attached to the surface of bacteria. [T/F] Proteins are the molecular machinery that play various functions in the living systems. The unique folded structure (i.e., 3D structure) of proteins plays an important role in their function. True While lungs are are contained in space of approx. 4L but present a surface area of approx. 85 m^2 for gas exchange. This is achieved by the lung's -----. Highly branched structure [T/F] Cardiovascular system include systematic circulation and lymphatic circulation. False [T/F] According to the class lecture, DNA are the simplest unit of living matter. False [T/F] Even if you are unfamiliar with the topic or the scientists who authored a particular study, you can trust peer-reviewed work to meet certain standards of scientific quality. True [T/F] Pub med and Google scholar are good resources for finding research papers. True [T/F] According to the class slides, Peer-reviewed work is always correct. This is because it has met the standard of science. False [T/F] According to how to read research papers algorithm (presented in the class) we look for the main claim in the figures. False [T/F] It is acceptable and fine for researchers (for example you in this course) to use the results published in a "Predatory journal". The name only implies that the journals charge extra fees from the scientists to publish their work. False [T/F] After a scientific research passes through peer review it is never necessary to try to replicate its results. False [T/F] There exists a "connection" between the gut microbiome and the brain. For example, majority of serotonin (a key messenger molecule for nerve cells) is created in the gut by microbes True According to the week-3 material: We look for a paper's ---- in the abstract. And the main evidence in the ----. a. figures, conclusion b. abstract, figures c. conclusion, figures d. abstract, conclusion a. figures, conclusion d. abstract, conclusion Homeostasis --- is defined as any self-regulating process by which biological systems tend to maintain stability while adjusting to conditions that are optimal for survival. According to Week 4's content, which statement is FALSE? a. Drawing a black box diagram is an example of standardization b. Microscopes are an example of a bio-instrumentation c. Standardization is used to enable division of labor d. Abstraction is used as a tool for dealing with complexity a. Drawing a black box diagram is an example of standardization [T/F] Human biomechanics only apply to the skeletomuscular systems. False
