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? Choices: - ph scale - celsius - centigrade - kelvin scale A:
kelvin scale

(Answer)
boron
Ques: Answer the following question given this paragraph: Components along the same axis, say the x-axis, are vectors along the same line and, thus, can be added to one another like ordinary numbers. The same is true for components along the y-axis. (For example, a 9-block eastward walk could be taken in two legs, the first 3 blocks east and the second 6 blocks east, for a total of 9, because they are along the same direction. ) So resolving vectors into components along common axes makes it easier to add them. Now that the components of R are known, its magnitude and direction can be found. Step 3. To get the magnitude. Q: Vectors along the same line can be what to one another like ordinary numbers? Choices: - noted - taken - lost - added A:
Ans: added

angiosperm seeds
Ques:Answer the following question given this paragraph: Magnetite is a magnetic mineral found in lava. The magnetite points to the magnetic north pole when it cools. Q: What is the name of the magnetic material found in lava? Choices: - meteorite - hemoglobin - magnemite - magnetite A:

Ans:magnetite
Question: Answer the following question given this paragraph: The first species to colonize a disturbed area such as this are called pioneer species (see Figure below ). They change the environment and pave the way for other species to come into the area. Pioneer species are likely to include bacteria and lichens that can live on bare rock. Along with wind and water, they help weather the rock and form soil. Once soil begins to form, plants can move in. At first, the plants include grasses and other species that can grow in thin, poor soil. As more plants grow and die, organic matter is added to the soil. This improves the soil and helps it hold water. The improved soil allows shrubs and trees to move into the area. Q: What are species that are first to colonize a disturbed area called? Choices: - novel species - exploratory species - brave species - pioneer species A:
Answer:
pioneer species
