Which quantity is most relevant when determining the damage caused to a human body by an...
Electric current passing through a human body can be dangerous, even fatal, depending on the amount of current, the duration of the current, and the region of the body through which the current passes. However, currents less than about 0.5 mA are typically imperceptible. A current caused by a low potential difference typically travels through the outer layer of the skin. The resistance of the skin therefore determines how much current flows for a given potential difference. The resistance can...
Which of the following units quantifies the amount of biological damage caused by the absorption of radiation? (Please explain) A. rem B. seaborg C. rad D. faraday E. ohm
The most significant change in the human condition was caused by? O A. a. the discovery of fire B. b. the agricultural revolution O C. c. the invention of the potter's wheel O D. d. domesticating animals
In the Quantity Discount EOQ inventory model, which of the following items is NOT considered relevant in determining the lowest cost order quantity? A. The cost of placing an order. B. The individual purchase price of an item of inventory. C. The cost of carrying an item in inventory. D. The variability of demand during lead time. E. The annual demand for the product.
Which of the following is true about demand and quantity demanded? Select one: a. A change in demand is caused by a change in current price while a change in quantity demanded is caused by a change in some other factor. b. Both a change in quantity demanded and a change in demand are caused by a change in a factor other than the current price. c. A change in quantity demanded is caused by a change in current price...
Which of the following is not relevant in determining whether an activity is profit seeking or a hobby? a. Whether the activity is enjoyed by the taxpayer. b. The expertise of the taxpayers or their advisers. c. The time and effort expended. d. The relationship of profits earned and losses incurred. e. All of these are relevant factors.
5. The molecular composition of the human body is 80% which explains why formation of hydroxyl radicals are so important to producing radiation effects in the body 6. X-rays that are most useful for enhancing differential absorption in breast tissue and for maximizing radiographic contrast are in the range of_ _and_ keV. 7. For cells that undergo mitosis, the period of the cell cycle between mitotic events is termed 8. cells are more sensitive to radiation than mature cells.. 9....
Price Price Quantity Which graph illustrates an increase in quantity supplied caused by an increase in price? A) A B) B C) C D D
1. Autoimmunity is most likely to occur when A. An antigen impinges upon the immune system that crossreacts with a peripheral self-antigen. b. complement is activated c. toxins are produced by bacteria, causing tissue damage. d. an infection occurs that is prolonged. 2. What is (are) common to both MHC class 1 molecules and MHC class 2 molecules? choose the most correct answer a. both show limited variability from one individual to another. b. both bind peptides generated within the...
The human body can exhibit a wide range of resistances to current depending on the path of the current, contact area, and sweatiness of the skin. Suppose the resistance across the chest from hand to the right hand is 1.55 x 106 Ω. (a) How much voltage is required to cause possible heart fibrillation in a man, which corresponds to 490 mA of direct current? (b) Why should rubber-soled shoes and rubber gloves be worn when working around electricity? This...
