OPTIONS:
- linear fission
- binary fusion
- budding

A: binary fission

Q: Answer the following question given this paragraph: one degree Fahrenheit. Only 100 Celsius degrees span the same range as 180 Fahrenheit degrees, thus one degree on the Celsius scale is 1.8 times larger than one degree on the Fahrenheit scale 180 / 100 = 9 / 5. The Kelvin scale is the temperature scale that is commonly used in science. It is an absolute temperature scale defined to have 0 K at the lowest possible temperature, called absolute zero. The official temperature unit on this scale is the kelvin, which is abbreviated K, and is not accompanied by a degree sign. The freezing and boiling points of water are 273.15 K and 373.15 K, respectively. Thus, the magnitude of temperature differences is the same in units of kelvins and degrees Celsius. Unlike other temperature scales, the Kelvin scale is an absolute scale. It is used extensively in scientific work because a number of physical quantities, such as the volume of an ideal gas, are directly related to absolute temperature. The kelvin is the SI unit used in scientific work. Q: Which temperature scale is commonly used in science? A:

OPTIONS:
- ph scale
- celsius
- centigrade
- kelvin scale

A: kelvin scale

Q: Answer the following question given this paragraph: Heart: Coronary Artery Disease Coronary artery disease is the leading cause of death worldwide. It occurs when the buildup of plaquea fatty material including cholesterol, connective tissue, white blood cells, and some smooth muscle cellswithin the walls of the arteries obstructs the flow of blood and decreases the flexibility or compliance of the vessels. This condition is called atherosclerosis, a hardening of the arteries that involves the accumulation of plaque. As the coronary blood vessels become occluded, the flow of blood to the tissues will be restricted, a condition called ischemia that causes the cells to receive insufficient amounts of oxygen, called hypoxia. Figure 19.16 shows the blockage of coronary arteries highlighted by the injection of dye. Some individuals with coronary artery disease report pain radiating from the chest called angina pectoris, but others remain asymptomatic. If untreated, coronary artery disease can lead to MI or a heart attack. Q: What is the leading cause of death worldwide? A:

OPTIONS:
- lung disease
- cancer
- liver failure
- coronary artery disease

A: coronary artery disease

Q: Answer the following question given this paragraph: The mechanical advantage of a simple machine such as a pulley is the factor by which the machine changes the force applied to it. The ideal mechanical advantage of a machine is its mechanical advantage in the absence of friction. All machines must overcome friction, so the ideal mechanical advantage is always somewhat greater than the actual mechanical advantage of the machine as it is used in the real world. Q: What is something that all machines must overcome? A:

OPTIONS:
- stress
- work
- temperature
- friction

A:
friction
