Answer the following question given this paragraph: The system is isolated from other masses. This allows us to neglect any small effects due to outside masses. The conditions are satisfied, to good approximation, by Earth's satellites (including the Moon), by objects orbiting the Sun, and by the satellites of other planets. Historically, planets were studied first, and there is a classical set of three laws, called Kepler's laws of planetary motion, that describe the orbits of all bodies satisfying the two previous conditions (not just planets in our solar system). These descriptive laws are named for the German astronomer Johannes Kepler (15711630), who devised them after careful study (over some 20 years) of a large amount of meticulously recorded observations of planetary motion done by Tycho Brahe (15461601). Such careful collection and detailed recording of methods and data are hallmarks of good science. Data constitute the evidence from which new interpretations and meanings can be constructed. Q: Kepler's laws relate to the motion of what? Choices: - continents - oceans - the sun - planets A:
(Answer)
planets
Ques: Answer the following question given this paragraph: Discussions of colors can sometimes become confusing because of the difference between light emitters and light absorbers. Light absorbers, such as dyes and pigments, absorb frequencies from those that you see, while light emitters add frequencies to what you see. If I were to shine red light, green light, and blue light into your eye all at the same time, you would likely see some variation of white. If I were to mix red paint, green paint, and blue paint together, you would likely see black or some very dark color. Q: What do light emitters do to what you see? Choices: - divide frequencies - subtract frequencies - block frequencies - add frequencies A:
Ans: add frequencies

Answer the following question given this paragraph: Multicellular Photosynthetic Autotrophs hyphae are densely packed so it is difficult to see the individual structures when a mushroom is eaten. However, a mushroom is only a specialised reproductive part of the whole fungus. The main part of the fungi is underground in a whole web of hyphae, called a mycelium. In the mycelium, each fungal cell is separated from each other by a septum. Each fungal cell may have one or more nuclei and remains connected to the mycelium because the septa are porous, allowing cytoplasm to flow through the hyphae and fungal cell walls, made of a hard material called chitin. Some fungi do not have septa, and they appear to be large, branching, multinucleate cells. Q: A mushroom is only a specialised reproductive part of the whole fungus. the main part of the fungi is underground in a whole web of hyphae, called this? Choices: - detritus - hypothalamus - bacterium - mycelium A:
(A).
mycelium
Ques:Answer the following question given this paragraph: Polyprotic Acids and Bases As you learned in Chapter 4 "Reactions in Aqueous Solution", polyprotic acids such as H2SO4, H3PO4, and H2CO3 contain more than one ionizable proton, and the protons are lost in a stepwise manner. The fully protonated species is always the strongest acid because it is easier to remove a proton from a neutral molecule than from a negatively charged ion. Thus acid strength decreases with the loss of subsequent protons, and, correspondingly, the pKa increases. Consider H2SO4, for example: Figure 16.5. Q: What decreases with the loss of subsequent protons? Choices: - example strength - Movement strength - seawater strength - acid strength A:

Ans:acid strength
Ques: Answer the following question given this paragraph: The final product of the Calvin cycle is glucose. Q: What is the final product of the calvin cycle? Choices: - chloride - sucrose - insulin - glucose A:
Ans:
glucose
