Answer the following question given this paragraph: The Nature of Science Biology is a science, but what exactly is science? What does the study of biology share with other scientific disciplines? Science (from the Latin scientia, meaning "knowledge") can be defined as knowledge about the natural world. Science is a very specific way of learning, or knowing, about the world. The history of the past 500 years demonstrates that science is a very powerful way of knowing about the world; it is largely responsible for the technological revolutions. Q: The word science is derived from what latin word? Choices: - scefitana - scitifica - sceria - scentia A:
scentia

Answer the following question given this paragraph: Isotopes have the same number of protons and electrons, but a different number of neutrons. Q: Isotopes have the same number of protons and electrons, but a different number of what? Choices: - reactions - impurities - atoms - neutrons A:
(Answer)
neutrons
Ques: Answer the following question given this paragraph: Hydrates Many ionic compounds occur as hydrates, compounds that contain specific ratios of loosely bound water molecules, called waters of hydration. Waters of hydration can often be removed simply by heating. For example, calcium dihydrogen phosphate can form a solid that contains one molecule of water per Ca(H2PO4)2 unit and is used as a leavening agent in the food industry to cause baked goods to rise. The empirical formula for the solid is Ca(H 2PO4)2H2O. In contrast, copper sulfate usually forms a blue solid that contains five waters of hydration per formula unit, with the empirical formula CuSO 45H2O. When heated, all five water molecules are lost, giving a white solid with the empirical formula CuSO 4 (Figure 2.9 "Loss of Water from a Hydrate with Heating"). Q: Many ionic compounds occur as hydrates, compounds that contain specific ratios of loosely bound water molecules, called waters of hydration. waters of hydration can often be removed simply by doing this? Choices: - cooling - observing - melting - heating A:
Ans: heating
(Q).
Answer the following question given this paragraph: Diffusion into intestinal cells, where they are combined with proteins to create chylomicrons. Q: Intestinal cells combine with proteins to create what? Choices: - amino acids - chondrocytes - lipoproteins - chylomicrons A:
(A).
chylomicrons
Ques:Answer the following question given this paragraph: A sand dune has a gentle slope on the side the wind blows from. The opposite side has a steep slope. This side is called the slip face. Q: What is the term for the steep sloped side of a sand dune? Choices: - front face - break face - slide face - slip face A:

Ans:slip face
Ques: Answer the following question given this paragraph: Heavily vegetated lands are less likely to experience flooding. Plants slow down water as it runs over the land, giving it time to enter the ground. If the ground is too wet to absorb more water, plants still slow the water's passage. Slower water keeps all the water from entering the stream at once. Wetlands play a key role in minimizing the impacts of floods. Wetlands act as a buffer between land and high water levels. Flooding is often more severe in areas that have been recently logged. Q: Heavily vegetated lands are less likely to experience what? Choices: - expansion - drought - rains - flooding A:
Ans:
flooding
